(for details on the operation of the output modes, refer to input/ output mode settings on page page 22.) one-shot output time ( otim ) set the one-shot output time (0.01 to 99.99 s) for control output. one-shot output can be used only when c, r, k-1, p, q, a, or k-2 is selected as the output mode. output times other than 0.5 s or 0.05 s cannot be set with the dip switch and so use the operation keys if other settings are required. one-shot output 2 time ( otm2 ) set the one-shot output time (0.01 to 99.99 s) for control output (out2). one-shot output can be used only when c, r, k-1, p, q, a, or k-2 is selected as the output mode. output times other than 0.5 s or 0.05 s cannot be set with the dip switch and so use the operation keys if other settings are required. one-shot output 1 time ( otm1 ) set the one-shot output time (0.01 to 99.99 s) for control output (out1). one-shot output can be used only when d, l, or h is selected as the output mode. if the output time is set to 0.00, hold is displayed, and outputs are held. counting speed ( cnts ) set the maximum counting speed (30 hz/5 khz) for cp1 and cp2 inputs together. if contacts are used for input signal s, set the counting speed to 30 hz. processing to eliminate chatteri ng is performed for this setting. reset input signal width ( iflt ) set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total reset/reset 2 inputs together. if contacts are used for the input si gnal, set the input signal width to 20 ms. processing to eliminate cha ttering is performed for this setting. decimal point position ( dp ) decide the decimal point position for the present value, cp1/cp2 present values, set value (sv1, sv2), total count value, and dual count set value. prescale value ( pscl ) pulses input to the counter are c onverted according to the specified prescale value. (setting range: 0.001 to 99.999 for 6-digit models and 0.001 to 9.999 for 4-digit models.) example: to display the feed distance for systems that output 25 pulses for a feed length of 0.5 m in the form @@ . @@ m: 1. set the decimal point pos ition to 2 decimal places. 2. set the prescale value to 0.02 (0.5 25). observe the following points when setting a prescale value. set the set value to a value less than {maximum countable value ? prescale value}. example: if the prescale value is 1.25 and the counting range is 0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 ? 1.25). if the set value is set to a value great er than this, output will not turn on. output will turn on, however, if a present value overflow occurs (ffffff or ffff). npn/pnp input mode ( imod ) select either npn input (no-voltage input) or pnp input (voltage input) as the input format. when usi ng a two-wire sensor, select npn input. the same setting is used for all external inputs. for details on input connections, refer to input connections on page page 9. display color ( colr ) (displayed for terminal block models (except h7cx-a11 @ ) only.) set the color used for the present value. * output 2 for 2-stage models. with the twin counter, output 1 and output 2 will both turn off when the output status is off. either output 1 or output 2 will turn on when the output status is on. output off* output on* red red (fixed) grn green (fixed) org orange (fixed) r-g red green g-r green red r-o red orange o-r orange red g-o green orange o-g orange green 25 pulses encoder 0.5 m note: if the prescale value setting is incorrect, a counting error will occur. check that the settings are correct before using this function.
h7cx-a @ -n 19 counter absolute value setting/forecast value setting ( setm ) for the 2 count output mode, an absolute value setting ( abs ) or forecast value setting ( ofst ) can be set for set value 1. when a forecast value is set, specify the forecast value set value (i.e., the deviation for the set value). the forecast output (output 1) turns on when the present value reaches the forecast value. if the forecast set value is greater than or equal to the set value, the forecast output (output 1) will turn on as soon as counting starts. if the forecast value setting is used, specify the set value 2 minus the forecast value setting for set value 1. set value upper limit ( sl-h ) set the upper limit for the set value when it is set in run mode. the setting can be made from 1 to 9999 for 4-digit models and from 1 to 999999 for 6-digit models. forecast set upper limit ( pl-h ) set the upper limit for the forecast set value. the setting can be made from 1 to 9999 for 4-digit models and from 1 to 999999 for 6-digit models. batch count upper limit ( bl-h ) set the upper limit for the batch count value. the setting can be made from 1 to 9999 for 4-digit model s and from 1 to 999999 for 6-digit models. output allocation ( otst ) when using an h7cx-au @ -n model as a 2-stage counter, the output can be flexibly allocated to either stage 1 or 2. the transistor output can be allocated to sv1 and the contact output to sv2 or vice verse, as in the following tables. h7cx-au-n/-aud1-n h7cx-ausd1-n key protect level ( kypt ) set the key protect level. refer to key protect level on page page 36. output on count alarm set value ( on-a ) set the alarm value for the output on count. the limit can be set to between 0 1000 (0 times) and 9999 1000 (9,999,000 times). only the underlined values are set. the alarm will be disabled if 0 is set. if the total on count of the output exceeds the alarm set value, e3 will be displayed on the timer to i ndicate that the output on count alarm value was exceeded. refer to self-diagnostic function on page page 36 for information on the e3 display. on count alarm set values for outputs 1 and 2 (out1 and out2) ( on1a and on2a ) set the on count alarm values for the outputs 1 and 2. the limit can be set to between 0 1000 (0 times) and 9999 1000 (9,999,000 times). only the underlined values are set. the alarm will be disabled if 0 is set. if the total on count of instantaneous output 1 or 2 exceeds the alarm set value, e3 will be displayed on the timer to indicate that the output on count alarm value was exceeded. refer to self-diagnostic function on page page 36 for information on the e3 display. output on count monitor value ( on-c ) the monitor value is only displayed. it cannot be set. the output on count will be 1,000 times the displayed value. on count monitor va lues for outputs 1 and 2 (out1 and out2) ( on1c and on2c ) the monitor value for output 1 or 2 is only displayed. it cannot be set. the output on count will be 1,000 times the displayed value. output 1 output 2 off transistor (12-13) contact (3, 4, 5) on contact (3, 4, 5) transistor (12-13) output 1 output 2 off transistor (12-13) transistor with diode (3, 4, 5) on transistor with diode (3, 4, 5) transistor (12-13) set value 2 set value 1 0 control output 1 (out1) control output 2 (out2) count value example: f mode set value forecast value forecast set value 0 forecast output (out1) control output (out 2) count value example: f mode

30 h7cx-a @ -n tachometer explanation of functions tachometer operation items marked with stars can be set using the dip switch. tachometer input mode ( tinm ) set the count input mode to one of the following: 1 input ( f1 ), 2 inputs ( f2 ), error ( f3 ), absolute ratio ( f4 ), or error ratio ( f5 ). tachometer output mode ( totm ) set the output method for control output based on the comparison value. upper and lower limit (hi-lo), area (area), upper limit (hi-hi), and lower limit (lo-lo) can be set. (for details on the output modes, refer to output mode settings and operation on page page 34.) counting speed ( cnts ) set the maximum counting speed (30 hz/10 khz) for cp1 input. if contacts are used for input signal s, set the counting speed to 30 hz. processing to eliminate chatteri ng is performed for this setting. decimal point position ( dp ) decide the decimal point position for the measurement value, out1 set value, and out2 set value. prescale value ( pscl ) it is possible to display the rate of rotation or the speed of a device or machine to which the h7cx is mount ed by converting input pulses to a desired unit. if this prescaling function is not us ed, the input frequency (hz) will be displayed. it is also possible to specify time (seconds) as the display value. refer to display unit on page page 31 for details. the relationship between display and input is determined by the following equation. set the prescale value according to the unit to be displayed. displayed value = f f: input pulse frequency (number of pulses in 1 second) : prescale value (1) displaying rotation rate n: number of pulses per revolution example: to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@ . @ rpm: 1. set the decimal point position to 1 decimal places. 2. using the formula, set the prescale value ( ) to 1/n 60 = 60/5 = 12. (2) displaying speed n: number of pulses per revolution d: diameter of rotating body (m) d: circumference (m) observe the following points when setting a prescale value. set the set value to a value less than {maximum countable value ? prescale value}. example: if the prescale value is 1.25 and the counting range is 0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 ? 1.25). if the set value is set to a value great er than this, output will not turn on. * output will turn on, however, if a present value overflow occurs (ffffff or ffff}. averaging method ( avgt ) (only for tachometer operation) a simple average or moving average can be selected for the averaging. with the moving average method, the average of the measurement values is displayed eac h sampling cycle, in contrast to a simple average, with which the the average of the set number of samples is displayed. number of averaging times ( avgn ) flickering display and output chattering can be prevented using average processing. average proces sing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 time s, 8 times, or 16 times. the measurement cycle will be equal to the sampling cycle multiplied by the average processing setting (i.e., the number of times). average processing enables stable disp lays even for fluctuating input signals. set the optimum number of times for the application. auto-zero time ( auto0 ) the display can be force-set to 0 if there is no pulse for a certain period of time. this time is called the auto-zero time. set the auto-zero time to a time slightly longer than the estimated interval between input pulses. accurate measurement is not possible if the auto-zero time is set to a time shorter than the input pulse cycle. setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turni ng on. the auto-zero time is not applied to pulse width measurements. startup time ( stmr ) to prevent undesired outputs resulting from unstable inputs immediately after the power supply is turned on, it is possible to prohibit measurement for a set per iod of time, the startup time. it can also be used to stop meas urements and disable outputs until the rotating body reaches the normal ra te of rotation, after the power supply to the h7cx and rotating body are turned on at the same time. input mode input internal processing application 1 input count 1 none operation with only one input. 2 inputs counts 1 and 2 none operation with two independent inputs. error counts 1 and 2 count 1 input ? count 2 input measuring the difference between two inputs (error in number of revolutions). absolute ratio counts 1 and 2 count 1 input count 2 input measuring the ratio of two inputs (ratio of number of revolutions). error ratio counts 1 and 2 (count 1 input ? count 2 input) count 2 input measuring the ratio of error for two inputs (measuring the error ratio of number of revolutions). display unit prescale value ( ) rpm 1/n 60 rps 1/n display unit prescale value ( ) m/min d 1/n 60 m/s d 1 /n d: diameter of rotating body (m) note: if the prescale value setting is incorrect, a counting error will occur. check that the settings are correct before using this function. startup time display time comparison value (lower limit) output (lower limit) power supply

h7cx-r @ -n 45 explanation of functions basic functions input mode the mode can be switched between tachometer mode and amd- compatible mode. tachometer mode use this mode to measure the pulse frequency (hz). amd-compatible mode use this mode to measure the pulse cycle (s). counting speed set the maximum counting speed (30 hz /10 khz) for input. if contacts are used for input signals, se t the counting speed to 30 hz. processing to eliminate chattering is performed for this setting. output mode set the output method for control output based on the comparison value. upper and lower limit (hi-lo), area (area), upper limit (hi), and lower limit (lo) can be set. for the h7cx-rw @ , the upper limit (hi- hi) and lower limit (lo-lo) can be set. (for details on the operation of the output modes, refer to output mode settings on page page 49.) averaging method ( avgt ) simple averaging or a moving average can be selected for the averaging method. with a moving average, the average measurement value is displayed every sampling cycle or pulse cycle, in contrast to simple averaging, for which the average value is displayed for the set number of samples. number of averaging times flickering display and output c hattering can be prevented using average processing. average proces sing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, or 8 times. for a measurement frequency of 5 hz or higher using a tachometer, the average will be equal to the samp ling cycle (200 ms) multiplied by the averaging setting (i.e., the number of times). for less than 5 hz, the frequency will be measured when the input pulse comes. average processing pr oduces a stable display even for fluctuating input signals. set the optimum number of times for the application. if amd-compatible mode is used, the measurement cycle will be measured when the input pulse is received. the output will change, however, when the comparison val ue is exceeded even if averaging is enabled. npn/pnp input mode select either npn input (no-vo ltage input) or pnp input (voltage input) as the input format. when usi ng a two-wire sensor, select npn input. the same setting is used for all external inputs. for details on input connections, refer to input connections on page page 40. advanced functions decimal point position ( dp ) decide the decimal point positi on for the measurement value and comparison value. prescale value ( psc l) it is possible to display the rate of rotation or the speed of a device or machine to which the h7cx is mount ed by converting input pulses to a desired unit. if the default prescaling value (1 ,000) is used, the input frequency (hz) will be displayed. the relationship between display and input is determined by the following equation. set the prescale value according to the unit to be displayed. displayed value = f f: input pulse frequency (number of pulses in 1 second) : prescale value (1) displaying rotation rate n: number of pulses per revolution example: in order to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@ . @ rpm: 1. set the decimal point position to 1 decimal places. 2. using the formula, set the prescale value ( ) to 1/n 60 = 60/5 = 12. (2) displaying speed n: number of pulses per revolution d: diameter of rotating body (m) d: circumference (m) observe the following points when setting a prescale value. set the set value to a value less than {maximum countable value ? prescale value}. example: if the prescale value is 1.25 and the counting range is 0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 ? 1.25). if the set value is set to a value gr eater than this, output will not turn on. auto-zero time ( auto0 ) it is possible to make the settings so that the frequency will be force- set to 0 if there is no pulse for a s pecified period of time. this time is called the auto-zero time. cycle (s) display unit prescale value ( ) rpm 1/n 60 rps 1/n display unit prescale value ( ) m/min d 1/n 60 m/s d 1/n d: diameter of rotating body (m) note: if the prescale value setting is incorrect, a counting error will occur. check that the settings are correct before using this function. note: set the auto-zero time to a time slightly longer than the estimated interval between input pulses. it will not be possible to make accurate measurements if the auto-zero time is set to a time shorte r than the input pulse cycle. setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turning on.
46 h7cx-r @ -n startup time ( stmr ) in order to prevent undesired output resulting from unstable input immediately after the power supply is turned on, measurement can be prohibited for a set time at startup. it can also be used to stop measurement and disable output until the rotating body reaches the normal rate of rotation, after the power supply to the h7cx and rotating body are turned on at the same time. peak/bottom hold enabled ( dhld ) this function records the peak and bottom (i.e., minimum) values after counting starts (after turnin g on the power supply or changing the configuration selecti on mode or function setting). the peak value is also held when the power supply is interrupted. output hysteresis ( hys ) this setting can be used to prevent output chattering if the measurement value fluctuates slightly near the set value. in thachometer mode, the measurem ent value after prescaling is set. output off delay ( offd ) this function delays the timing for turning off comparative output by a certain time. the on time can be held for the set time if the comparative result changes in a short time. operation will continue and outputs will not change while holding the value. set value upper limit ( sl-h ) set the upper limit for the set value when it is set in run mode. key protect level ( ypt ) set the key protect level. refer to key protect level on page page 48. output on count alarm set value ( on-a ) set the alarm value for the output on count. the limit can be set to between 0 1000 (0 times) and 9999 1000 (9,999,000 times). only the underlined values are set. the alarm will be disabled if 0 is set. if the total on count of the output exceeds the alarm set value, e3 will be displayed on the timer to indicate that the output on count alarm value was exceeded. refer to self-diagnostic function on page page 48 for information on the e3 display. on count alarm set values for outputs 1 and 2 (out1 and out2) ( on1a and on2a ) set the on count alarm values for the outputs 1 and 2. the limit can be set to between 0 1000 (0 times) and 9999 1000 (9,999,000 times). only the underlined values are set. the alarm will be disabled if 0 is set. if the total on count of instantaneous output 1 or 2 exceeds the alarm set value, e3 will be displayed on the timer to indicate that the output on count alarm value was exceeded. refer to self-diagnostic function on page page 48 for information on the e3 display. output on count monitor value ( on-c ) the monitor value is only displayed. it cannot be set. the output on count will be 1,000 times the displayed value. on count monitor values for outputs 1 and 2 (out1 and out2) ( on1c and on2c ) the monitor value for output 1 or 2 is only displayed. it cannot be set. the output on count will be 1,000 times the displayed value. startup time display time comparison value (lower limit) output (lower limit) power supply outx1 outy2 display value comparison value 2 hysteresis hysteresis comparison value 1 set the hysteresis for when the output turns off.

h7cx- @ -n 52 safety precautions for all h7cx series (common) do not allow pieces of metal, wire clippings, or fine metallic shavings or fillings from installation to enter the product. doing so may occasionally result in electric shock, fire, or malfunction. minor injury due to explosion may occasionally occur. do not use the counter where subject to flammable or explosive gas. fire may occasionally occur. tighten the terminal screws to the rated torque. h7cx terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 nm) p2cf socket terminals: 4.4 lb-in (0.5 nm) minor injury due to electric shock may occasionally occur. do not touch any of the terminals while power is being supplied. be sure to mount the terminal cover after wiring. the life expectancy of the output relay varies considerably according to its usage. use the output relay within its rated load and electrical life expectancy. if the output relay is used beyond its life expectancy, its contacts may become fused or there may be a risk of fire. also, be sure that the load current does not exceed the rated load current and when using a heater, be sure to use a thermal switch in the load circuit. minor electric shock, fire, or malfunction may occasionally occur. do not disassemble, modify, or repair the counter or touch internal components. the panel surface of the h7cx-a/- r is water-resistant (conforming to nema4, ip66, ul type 4x (i ndoor use only). to protect the internal circuits from water penetration through the space between the h7cx and operating panel, wate rproof packing is included. attach the y92f-30 adapter with sufficient pressure with the reinforcing screws so that water does not penetrate the panel. when mounting the counter to a panel, tighten the two mounting screws alternately, a little at a ti me, so as to keep them at an equal tightness. if the panel screws are tightened unequally, water may enter the panel. store the counter at the specified temperature. if the counter has been stored at a temperature of less than ? 10 c, allow the counter to stand at room temperature for at least 3 hours before use. mounting the counter side-by -side may reduce the life expectancies of internal components. use the counter within the specified ranges for the ambient operating temperature and humidity. do not use in the following locations: locations subject to sudden or extreme changes in temperature. locations where high humidity may result in condensation. do not use the counter outside of the rated ranges for vibration, shock, water exposure, and oil exposure. do not use this counter in dusty environments, in locations where corrosive gasses are present, or in locations subject to direct sunlight. install the counter well away from any sources of static electricity, such as pipes transporting moldi ng materials, powders, or liquids. internal elements may be destroyed if a voltage outside the rated voltage range is applied. be sure that polarity is co rrect when wiring the terminals. separate the counter from sources of noise, such as devices with input signals from power lines carrying noise, and wiring for i/o signals. do not connect more than two crimp terminals to the same terminal. up to two wires of the same size and type can be inserted into a single terminals. use the specified wires for wiring. applicable wires: awg 18 to awg 22, solid or twisted, copper install a switch or circuit brea ker that allows the operator to immediately turn off the power, and label it to clearly indicate its function. when the counter is operated with no-voltage input (npn input), approximately 14 v is output from th e input terminals. use a sensor that contains a diode. use a switch, relay, or other cont act so that the rated power supply voltage will be reached within 0.1 seconds. if the power supply voltage is not reached quickly enough, the counter may malfunction or outputs may be unstable. use a switch, relay, or other contact to turn the power supply off instantaneously. outputs may malfunction and memory errors may occur if the power supply voltage is decreased gradually. when changing the set value during operation, because the h7cx uses a constant read-in system, out put will turn on if the set value is equal to the present value. when changing the comparison value during operation, because the h7cx uses a constant read-in system, the output status will change if the comparison value is changed to a value on the other side of the present value. if the set value and present value are both 0, the output will turn on for the default setting. the output will turn off during a reset operation. when the power is turned on using the factory settings, the output will turn on after 999.9 s if no pulses are received as count input. do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. they will damage the external finish. confirm that indications are wo rking normally, including the backlight led, and lcd. the indi cator leds, lcd, and resin parts may deteriorate more quickly depending on the application environment, preventing normal i ndications. periodic inspection and replacement are required. the waterproof packing may deteriorate, shrink, or harden depending on the application envir onment. periodic inspection and replacement are required. caution precautions for safe use 0.5 to 1 mm it is recommended that the space between the screw head and the adapter be 0.5 to 1 mm. input 0 v sensor diode
h7cx- @ -n 53 h7cx models with a 12 to 24-vdc power supply use a transformer-free power supply method in which the power supply terminals are not isolated from t he signal input terminals. if a non- isolating dc power supply is used, unwanted current paths may occasionally burn or destroy internal components depending on the wiring. always check the wiring sufficiently before use. an inrush current of approx. 10 a will flow for a short time when the power supply is turned on. if the capacity of the power supply is not sufficient, the counter may not start. be sure to use a power supply with sufficient capacity. maintain voltage fluctuations in the power supply within the specified operating voltage range. when turning the power on and off, input signal reception is possible, unstable, or impossible as shown in the diagram below. inrush current generated by turni ng on or off the power supply may deteriorate contacts on the pow er supply circuit. turn on or off to a device with the rated current of more than 10 a. the capacity of the external pow er supply is 100 ma at 12 v. when using a 24 vac/12 to 24 vdc power supply, reduce the load with the power supply voltage, as show n in the following diagram (dc power supplies only). if the prescale value setting is in correct, a counting error will occur. check that the settings are corre ct before using this function. make sure that all settings are appropriate for the application. unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate. do not leave the counter for long periods at a high temperature with output current in the on state. doing so may result in the premature deterioration of inter nal components (e.g., electrolytic capacitors). eeprom is used as backup memory when the power is interrupted. the write life of the eeprom is 100,000 writes. the eeprom is written at the following times: when the power supply is turned off when switching from configuration selection mode or function setting mode to run mode dispose of the product according to local ordinances as they apply. attach the front panel when using the counter. the tabs in the middle of each of four sides secu re the front panel to the main body. to remove the panel, widen the four tabs and pull the panel toward you. to mount the panel, fit all four tabs correctly into the grooves on the main body. when conforming to emc standards, refer to the information provided in this datasheet for c able selection and other conditions. this is a class a product. in resi dential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference. h7cx-a @ -n: basic insulation is provided between power supply and input terminals, between power supply and output terminals, and between input and output terminals. (however, no insulation is provided between the power suppl y and input terminals for the h7cx-a @ d-n.) h7cx-r @ -n: basic insulation is provided between power supply and input terminals and between input and output terminals. when double insulation or reinforced insulation is required, apply double insulation or reinforced insulation as defined in iec 60664 that is suitable for the maximu m operating voltage with clearances or solid insulation. connect the input and output termi nals to devices that do not have any exposed charged parts. precautions for correct use input impossible 200 ms 5 ms 0 to 90 ms 0 to 1 s possible unstable unstable impossible power supply on off power supply voltage (vdc) 10.8 15 100 20 load current (ma) conformance to en/iec standards ta b s grooves
