Leadshine DMA860H Stepper Motor Driver 18-80VAC 24-110VDC 7.2A

Original Datasheet

Description:
The DMA860H 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. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DMA860H can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DMA860H an ideal choice for high requirement applications.

• 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

• 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 18-80VAC or 26-113VDC

• 8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A

• Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input

• Automatic idle-current reduction

• Suitable for 2-phase and 4-phase motors

• Support PUL/DIR and CW/CCW modes

• Over-voltage, over-current protections

Specifications:

Features:
1. The MA860H is a high-performance micro-stepping drive based on pure-sinusoidal current control technology.
2. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters)
according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement
and have better performances at a higher speed than most of the drives on the markets.
3. 32-Bit DSP digital controller method, support PUL/DIR and CW/CCW modes.
4. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
5. It is suitable for all kinds of large and medium scale automation equipment, such as engraving machine, cutting machine, packaging machine, CNC machine tools, automatic assembly equipment, etc..
