... Hoists • Actuator Systems DESCRIPTION The OMC507 is a three phase brushless DC Motor Controller Driver. The OMC507 quadrant controller and provides control of motor current (torque) in proportion to the input current command. The versatility of the OMC507 allows the user to either provide an analog or a TTL PWM current command signal externally set an analog current command onboard ...

... PIN DESCRIPTIONS / FUNCTIONALITY VCC (Pin 1) -- The Vcc Supply input provides bias voltage to all of the internal control electronics within the OMC507, and should be connected to a nominal +15Vdc power source. GROUND (Pin 2) -- The voltages that control the OMC507 are referenced with respect to this pin. ...

... J1-14). Besides the implementation of the cycle-by-cycle peak current limit/overcurrent limit protection feature of the OMC507, the output of the current sense amplifier is fed into the error amplifier which is configured as a differential amplifier. An error signal representing the difference between the current command input and the value of the amplified current sense signal is produced ...
