Product Description

The MMP742038-24 is part of a family of smart motor control boards for servo motor applications. This design is capable of delivering 38W continuous power and is designed to fit NEMA 17 format 42mm motors.

Board features:

- Embedded angular sensor

- FOC control

- Selectable position, speed, and torque loop mode

- RS485 and PULSE/DIR input interface.

The user can choose from three options: speed control mode, position control mode, or speed/position control mode.

Easy-to-use GUI software provides flexibility as it allows users to optimize the design online through the RS485 control interface. The parameters are saved in the control board’s non-volatile memory.

Users can also order a complete motor (MSM942038-24). A datasheet for the MSM942038-24 is available for download at
