Gear Drive (Conveyor Motor) Speed Controller (CMSC)

The CMSC converts single-phase line voltage to a three-phase output. The speed of the gear drive is controlled by the frequency output of the CMSC. The CMSC receives an input voltage (0-10 VDC) from the control board and adjusts the frequency output to the gear drive.
