Digital Stepper Motor Driver DM542 1.0-4.2A 18-50VDC for Nema 17, 23 Stepper Motor

The DM542 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 optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM542 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542 an ideal choice for high requirement applications. It is highly recommended to work as nema 17 driver and nema 23 driver.

Key Features:

• Support PUL/DIR mode
• Automatic idle-current reduction
• Over-voltage and over-current protections
