3-Phase Stepper Motor Driver 3MA860 for NEMA 23 34 Stepper DC18-80V AC18-60V Input 2.0-8.3A Output for CNC

Description:
3MA860 Subdivision hybrid stepping motor driver, with 18-80V DC or 18~60V AC power input supply, suitable for drive voltage 24V~80V, current less than 7.2A, NEMA 23~NEMA34 (frame 57 ~86 mm diameter) three-phase hybrid stepping motor. With technology of AC servo drive current loop subdivision control, the torque of drove motor is stable, smooth running under low sped, small vibration and noise. The torque under high speed and positioning is also significantly higher than two-phase stepping motor.

Features:
- Average current control, two-phase sinusoidal output current drive
- 18-80V DC or 18~60V AC power input supply
- Opto-isolated input /output
- Overvoltage, under-voltage, over-current, short circuit protection phase
- 16 Subdivision and automatic half current function
- 8 options of output phase current setting
- With offline command input
- High speed start
- High-speed torque

Application:
Widely used in engraving machines, CNC machine tools, packaging machinery, transmission equipment and other devices that require a higher resolution.

The control signal definitions:
- PLS+: Positive of pulse signal input
- PLS-: Negative of pulse signal input
- DIR+: Positive terminal of  step directions input signal
- DIR-:  Negative terminal of  step directions input signal
- ENA+: Positive terminal of enabling offline input signal
- ENA-: Negative terminal of enabling offline input signal   

Offline enable signal is active once driving failure, and prevent any effective pulse, at the same time, the output power of the drive components is closed, and motor no maintain torque.

Package included:
- 1 x 3-Phase Stepper Motor Driver
