25 h7cr h7cr applications of operating modes n single operating modes single operating modes are basic modes, among which, mode n is the most basic (input the reset signal to restart). mode n the displayed count-up value is on hold. example: cutting objects to specified size the object is advanced for a specified distance measured by encoder pulses to determine correct length for cutting. n repetitive operating modes modes r and c are typical of repetitive operating modes (the counter internally resets itself after each counting operation and then restarts). the counter begins the next counting operation after the present output is processed. mode r the displayed count-up value is on hold. example: portion control of material or ingredients the valve is closed when the supplied quantity of cookie batter or blended ingredient has reached a specified amount. mode a select mode a for a one-shot output of the count-up signal used in mode n. the displayed count-up value is on hold. mode a can be used for a start signal for sequence control equipment. mode f go to mode f to monitor the number of overrun objects. the process value is displayed normally. it is possible to monitor the number of overrun objects upon interruption of the operation after a specified number of objects are counted. mode k select mode k for the one-shot output of the count-up signal used in mode f. mode k can be used as a start signal for sequence control equipment. rotary encoder counter programmable controller wood mode q choose mode q to view the process value continuously. there is no difference in operation between mode r and mode q. mode c the counting operation restarts upon counting up. the process value is displayed continuously. example: marking material at regular intervals a roll of film being advanced is marked at regular intervals based on encoder input. cookie batter valve opening/ closing counter rotary encoder mode p choose mode p to put the count-up value on hold (display is on hold while the one-shot output is on). there is no difference in operation between mode c and mode p. rotary encoder counter ink cutter control
