Stepmotor driver SMD-9.0

SMD-9.0 is a stepper driver for high torque applications. This unit control stepmotors with current per phase up to 9.0A, provides bipolar connection. Microstepping and current reduction functions are provided.

The speed-torque performance largely doesn't depend on a microstepping mode. Please, refer to the speed-torque curves (at the right side of this page).

SMD-9.0 control speed, direction and position of step motor. For control pulse signal STEP and level signal DIR are used. Additional ENABLE input is intended for sudden motion stop.
