Features:

● Can drive 4-wire, 8-wire two-phase stepper motor
● Signal input: PUL+ and PUL- are the positive 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.
● Power-on parameter auto-tuning function
● Precision current control greatly reduces motor heating
● The current is automatically halved at rest
● Built-in micro-segment
● Optically isolated signal input, strong anti-interference ability
● With overvoltage, overcurrent and other protection functions

The user manual for you to know more:

Specifications:

– Drive dimensions are: 117 * 78 * 34mm

– The mounting hole distance is 111mm.

– Maximum current: 7.2A, resolution: 0.1A
– Subdivision range: 400~25600ppr
– Impulse response frequency: 200KHz
– DC power supply 
– The input voltage range: 24~80VDC or AC both OK;
– Power supply is greater than 200W. Recommend 48VDC or 48V AC
– Operating Temperature: -10℃~45℃ 

Installation instructions:
 
① Can be installed horizontally or vertically (vertical installation is recommended). When installed, it should be attached to the metal cabinet to facilitate heat dissipation.
Motor Interface
The A+ and A- are connected with the positive and negative ends of the A phase winding of the stepping motor; B+ and B- are connected with the positive and negative ends of the B phase winding of the stepping motor. When the A and B two phase windings are switched, the motor direction is reversed.
Operating current setting
The output current of the driver is set by the three dial switches of SW1-SW3, and the output current has 8 levels. 
④ Indicator light
The drive has red and green lights. The green light is the power indicator lamp. When the drive is powered on, the green light is always on; the red light is the fault indicating lamp, and when the overvoltage and overcurrent faults occur, the trouble 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.
Automatic half current function:
Set the auto semi-current function of the drive through the SW4. The OFF indicates that the quiescent current is set at half of the dynamic current, and the ON represents the same static current as the dynamic current. For general use, the SW4 shall be set to OFF to reduce heating and improve the reliability of the motor and actuator. After the pulse string stops, about 0.4seconds or so, the current automatically reduce by 50% (actual value 65%), the calorific value theoretically reduces 35%.
Microstep subdivide setting:
By the SW5-SW8 four dial switch set micro step to subdivide, the total of 15 stalls microstep. When the user sets the subdivision, the drive should be stopped. The micro set, please check the drive panel.
