DM542, DM556 or DM860H stepper motor driver




2-phase Digital Stepper Motor Driver

It is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with other analog or TB6600H chips driver, it can drive a stepper motor at much lower noise, lower heating, and smoother movement.

Key Features:
* Anti-Resonance provides optimal torque and nulls mid-range instability
* Motor auto-identification and parameter auto-configuration when power on, offer optimal 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 from 400 to 25600
* Soft-start with no “jump” when powered on
* Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
* Automatic idle-current reduction
* Suitable for 2-phase and 4-phase motors
* Support PUL/DIR mode
* Over-voltage and over-current protections

Driver input signal interface function
Signal interface
Signal pretext
PLS+ and PLS- control the positive and negative end of the pulse signal. DIR+ and DIR- are the positive and negative ends of the direction signal. 24V needs 2K resistors
A+ and A- connect the positive and negative ends of stepper motor A phase winding, B+ and B- connect the positive and negative ends of stepper motor's B phase winding. When the A.B two phase winding is switched, the direction of the motor can be reversed
Motor Interface
Using the DC power supply, the working voltage range is suggested to be 20-50VDC, the power supply’s power is more than 100W. According to the actual use, the input is suitable for less than DC 40V
Indicator light
The driver has two indicators:red and green. The green light is the power indicator. When the drive is in charge, the green light is always on. The red light is the fault indicator. When overvoltage and overcurrent occurs, the red light is on. After the fault is cleared, the red light goes out. When the driver fails, recharging and reusing is needed to remove the fault.
