Attention: Please read this manual carefully before using the driver.
1 Introductions & Features
The Y series Open‐loop drivers are divided according to the driving power, which are DM420Y, DM542Y,
DM556Y, DM860Y. The Y series open loop drivers are digital stepper drivers with simple design and
easy setup. By implementing the advanced stepper control technology, this stepper drive is able to
power 2‐phase and 4 phase stepper motors smoothly with optimal torque and low motor heating &
noise. All the micro step and output current are done via DIP switches. Therefore, the Y series open
loop drivers are ideal choices for applications requiring simple step & direction control of NEMA 8, 11,
14, 16, 17, 23, 24 and 34 stepper motors. And features are showing below:
Anti‐Resonance for optimal torque, extra smooth motion, low motor heating and noise
Motor auto‐identification and parameter auto‐configuration for optimal torque from wide‐range
motors
Step & direction (PUL/DIR) control
Multi‐Stepping for smooth motor movement
TTL compatible and optically isolated inputs
Input voltage DC18~36V, DC20~50V, DC36~110V(AC18~80V)
Micro‐step resolutions: 200~6400, 200~40000, 400~40000
Output current settings: 0.3~2.2A, 1~4.2A, 1.7~5.6A, 2.4~7.2A
Soft‐start with no “jump” when powered on
Automatic idle‐current reduction
Protections for over‐voltage and over‐current
