Description

Introduction

Compared with other TB6600H analog chip driver, the DM542 digital stepper motor driver can drive the stepper motor with much lower noise, less heating and smooth movement. It is suitable for 4-wire, 6-wire or 8-wire two-phase stepper motor Nema 17 and Nema 23 with less than 4.2 A phase current. The drive voltage is from 20VDC to 50VDC.

The driver is intended for use in a non-industrial environment. Recommended for use in an industrial environment Leadshine DM542.

Key Features:

  • Protection against overvoltage and overcurrent
  • DC power supply 20-50 VDC (36 VDC recommended)
  • Maximum drive current 4.2 A
  • You can set the standby current to half
  • 15 selectable micro step resolutions from 400 to 25600
  • Input pulse frequency up to 200 KHz, TTL compatible and optically isolated input
  • Logic signal current: 7 ~ 16mA (typically 10mA)

DM542 digital stepper motor driver n signal interface details:

The controller's control signals can be active at high or low electrical levels. When the high electrical level is active (common cathode connection), all control negative signals are connected to GND. When the low electrical level is active (common anode connection), all positive control signals are connected to a positive voltage. See the images below for details:

  • Common cathode connection

  • Common anode connection

You can use a 5 – 24 V controller signal, but make sure the appropriate resistor is used:

Amplitude of the signal External limiting resistor R
5V Without R.
12V 1kΩ
24V 2kΩ

Since the DM542 driver operates on a 5V signal, it is ideal for controlling with an Arduino or other 5V controller. If you need help connecting, you can always contact us contact us. We will be happy to help you.

Motor and power supply interface details:

Motor terminals A+ 4 motor wires must be connected. In most cases, these wires are color coded. The color associated with the winding depends on the motor. See engine documentation for details.

Summary

Shown below are all connections to the DM542 stepper motor driver required for proper system operation (this is an example of a common anode connection ("EN" and resistors (R) not connected)). The stepper motor driver acts as a central unit that allows current to flow through the motor windings based on signal pulses from the microcontroller unit (MCU):
