DM542T Digital Stepper Driver 1.0-4.2A 20-50VDC for Nema 17, Nema23, Nema 24 Stepper Motor
DM542T Digital Stepper Driver 1.0-4.2A 20-50VDC for Nema 17, Nema23, Nema 24 Stepper Motor
The DM542T is a fully digital stepper driver developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing proper torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to suitable modes with different motors. Compared with traditional analog drives, DM542T can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542T suitable for high requirement applications.
Key Features:
Input voltage 20-50VDC
Anti-Resonance provides suitable torque and nulls mid-range instability
Motor auto-identification and parameter auto-configuration when power on, offer quick responses with different motors
Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
15 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000
Soft-start with no “jump” when powered on
8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A

I saw that this product had a high rating on the website, so I bought it to try, and the effect did not disappoint me.

I was lucky to get this driver for me. I don't need high power output for any of my applications, but the microstepping is very smooth. This driver is easy to connect, install, and use if you are familiar with stepper and direction control.

Excellent stepper driver better than the mini pololu MCs, if you want better results for 3d prints or accuracy for a cnc machine, this driver is a good choice for your project.

Amazing difference. Purchased this to replace an old TB6560. I read good things about this driver and I decided to give it a try.
My home built CNC router was loosing steps occasionally and it was loud. There was a lot of resonance in the stepper and ball-screw system.
This new drive set to the same microstepping (1/8) and the same current setting made a huge difference. I can barely hear the motors when homing at low step rate and very quiet at higher speeds. The anti-resonance and wave shaping circuit must really work as advertised to make such a difference.
Big thumbs up.

Easy to use. Runs cool. Read the manual, set the switches, wired them up and have not had to do anything else. 60+ running hours on 3 drivers.
