Digital Stepper Motor Driver 2.4-7.2A 20-80VDC DM860I for Nema 34 Stepper CNC

Description

Overview
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
Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors
Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement, works well as Cnc drive as well.
16 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 51200, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 40000
Soft-start with no "jump" when powered on
Input voltage 20-80VDC
8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A
