Digital Stepper Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 Motor

The DM860T 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, DM860T can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM860T an ideal choice for high requirement applications.
