| 10A8DD Series SERIES 10A-DD PWM BRUSH TYPE SERVO AMPLIFIERS Model: 10A8DD FEATURES: * * * * * Surface-mount technology Small size, low cost, ease of use Adjustable current limit Four quadrant regenerative operation Agency Approvals: ADVANCED MOTION CONTROLS 3805 Calle Tecate, Camarillo, CA 93012 Tel: (805) 389-1935, Fax: (805) 389-1165 B-9 10A8DD Series DESCRIPTION: The 10A8DD PWM servo amplifier is designed to drive brush type DC motors. The PWM frequency is determined by the PWM input signal. The 10A8DD is fully protected against over-voltage, over-current, over-heating and short circuits across motor, ground and power leads. This model interfaces with digital controllers that have a digital PWM output. It can also be used as a stand-alone system . The 10A8DD amplifier requires only a single unregulated DC power supply as all logic and control voltages are generated internally. PWM input determines the output duty cycle. "Direction In" determines which side of the "H bridge" output is switching. The current limit can be reduced by an external resistor. The voltage at the current monitor pin P1-11 is proportional to the actual motor current.

I Can be used to reduce the factory preset maximum current limit. This signal is proportional to the actual current in the motor leads. Scaling is 1V = 2A. Turns off all mosfets of the "H" bridge drive when high.
