2phase NEMA34 hybrid stepper motor driver DSP AC18V-80V 7.2A MC860H

Function

Operation instructions

Operating current setting

The output current of thedriver is set by the three dial switches of SW1-SW3, and the output currenthas 8 levels. For specific output current settings, refer to the drive panelinstructions.

Automatichalf current function

Setthe auto semi current function of the drive through the SW4. The OFFindicates that the quiescent current is set at half of the dynamic current,and the ON represents the same static current as the dynamic current. Forgeneral use, the SW4 shall be set to OFF to reduce heating and improvereliability of the motor and actuator. After the pulse string stops, about 0.4secondsor so, the current automatically reduces by 50% (actual value 65%), thecalorific value theoretically reduces 35%.

Microstep subdividesetting

By the SW5-SW8 four dialswitch set microstep subdivide, the total of 14 stalls microstep. When theuser sets the subdivision, the drive should be stopped. The micro set, pleasecheck the drive panel.

Indicator light

The drive has red andgreen lights. The green light is the power indicator lamp. When the drive ispowered on, the green light is always on; the red light is the faultindicating lamp, and when the overvoltage and overcurrent faults occur, thetrouble lamp is always on. After the fault is clear, the red light goes out.When the drive fails, only the power on and re enable to clear the fault.

Signal interface

PUL+ and PUL- are thepositive and negative ends of the control pulse signals; the DIR+ and DIR-are the positive and negative ends of the directional signal; ENA+ and ENA-are the positive and negative ends of the enabling signals.

Motor Interface

The A+ and A- areconnected with the positive and negative ends of the A phase winding of thestepping motor; B+ and B- are connected with the positive and negative endsof the B phase winding of the stepping motor. When the A and B two phasewindings are switched, the motor direction is reversed.

Powerinterface

DCpower supply, the input voltage range: 18~80VAC, power supply is greater than300W. Recommend AC36V to AC70V

Installation instructions

Drive dimensions are: 151* 97 * 48mm, the mounting hole distance is 143mm. It can be installedhorizontally or vertically (vertical installation is recommended). Wheninstalled, it should be attached to the metal cabinet to facilitate heatdissipation.
