Digital Stepper Driver 2.4-7.2A 20-80VDC for Nema 34 Stepper Motor CNC Drive

The DM860I is a fully digital stepper drive 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 that is suitable for Cnc drive . Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM860I can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM860I an ideal choice for high requirement applications, Cnc drive, etc.

Key Features

• Anti-Resonance provides optimal torque and nulls mid-range instability
