Output current programmable, from 1A to 4.2A.
Pulse input frequency up to 200 KHz.
Suitable for 2-phase and 4-phase motors.
Automatic idle-current reduction.
Over-voltage, over-current protection.
TTL compatible and optically isolated input.
Support PUL/DIR and CW/CCW modes.
Anti-Resonance, provides optimum torque and nulls mid-range instability.
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.
