M545D

Stepper Motor Driver Specification

Overview

   The M545D is a new generation microstep stepper motor driver. Due to the adoption of the advanced bipolar constant-current chopper driver technology, it shows stable operation, provides excellent high torque. Moreover, it significantly reduces the noises and vibration of the operating motor. The M545D has the feature of low-noise, low-vibration and low-heating. The M545D is DC24-50V power supply. It applies to 2-phase hybrid stepper motor under 4.5A current The M545D has 14l kinds of microsteps. The maximum step number is 51200 steps/rev (microstep is 1/256). The peak operating current ranges from 1.5A to 4.5A., and the output current has 8 stalls. The M545D has automatic semi-flow, motor misconnected,over-voltage, under-voltage, and over-current protection functions.

Applications

It can be applied in a variety of small scale automation equipment and instruments, such as labeling machine, cutting machine, packing machine, drawing machine, engraving machine, CNC machine and so on. It always performs well when it is used in equipment which requires for low-vibration, low-noise, high-precision and high-velocity.

Signal interface details:

The internal interface circuits of the driver are isolated by the opt coupler signals, R in the figure is an external current limiting resistor. The connection is differential. And it has a good anti-jamming performance.
