MC542P Analog Stepper Driver

Product Overview

The MC542P is a 57 digital stepper driver developed based on a high-performance, low-power ARM chip. Its driver features a built-in intelligent regulator with PID parameter self-tuning functionality, which automatically generates the most suitable parameters for different motors without manual adjustment, optimizing motor performance. This driver operates the motor with very low noise.

Features

Voltage input range: DC 20V to 50V Maximum peak current: 4.2A Speed range: 60 to 1200 ppr Analog input voltage range: 0~5V (customizable to 0~10V input) Insulation resistance: 500M Features overcurrent, overvoltage, and other protection functions

Driver Function Description

Driver Functions	Operating Instructions
Operating Current Setting	By SW1-SW3 three DIP switches to set the driver output current, with a total of 8 levels. For specific output current settings, please refer to the driver panel instructions.
Automatic Half-Current Function	Users can set the driver's automatic half-current function through SW4 . OFF means the static current is set to half of the dynamic current, ON means the static current is the same as the dynamic current. Generally, it is recommended to set SW4 to OFF during operation to reduce heating of the motor and driver and improve reliability. After the pulse train stops, the current automatically reduces after about 0.3 seconds. 50% (Actual value 55% ), theoretically reducing heat generation by 65%。
Speed Range Setting	By SW5-SW8 Four DIP switches are used to set the number of speed ranges of the driver, with a total of 15 speed range levels. When setting the speed, the driver should be stopped first. For specific speed range settings, please refer to the driver panel instructions.
Indicator Lights	The driver has two indicator lights: red and green. The green light is the power indicator and stays on when the driver is powered; the red light is the fault indicator and stays on when overvoltage or overcurrent faults occur. The red light turns off after the fault is cleared. To clear faults, power cycling and re-enabling the driver are required.
Signal Interface	+5V and AGND are 5V the positive and negative terminals of the power output; AI is the analog voltage input terminal; DIR+ and DIR- are the positive and negative terminals of the direction signal; ENA+ and ENA- are the positive and negative terminals of the enable signal.
Motor Interface	A+ and A- connects to the stepper motor A phase winding positive and negative terminals; B+ and B- connects to the stepper motor B phase winding positive and negative terminals. Swapping the two phase windings reverses the motor direction. A 、 B 两相绕组调换时，可使电机方向反向。
Power Interface	Powered by DC power supply, operating input voltage range: 20~50VDC , recommended operating voltage 36VDC , power supply greater than 100W.
Installation Instructions	Driver dimensions are: 117 × 78 × 34mm with mounting hole spacing of 111mm . It can be installed horizontally or vertically (vertical installation is recommended). During installation, it should be mounted tightly against a metal cabinet to facilitate heat dissipation.
