The CR640 Series microstep stepper motor drives take the advantages of advanced microstep control ASIC MSC7601B which fully intergraded all control functions needed for bipolar step motor microsteping control, achieve very good driving stability, high reliability at a low cost.

The CR640s cover the driving current range covers from 0. 7 to 7. 2A, and accept up to a 75V supply voltage. With the CR640s, the eight step resolutions, from 2 to 64 can be selected by the onboard dip switches. The drives also provide powerful protection ability including over current, low voltage and over temperature, and the ALARM OUT can be used to inform the system of a problem.
