Feature

• High performance, low price;
• Provides 32 kinds of microstep selection;
• Once the pulse stops for 100ms, phase current automatically reduce to 20%-80%.(It’s decided by STOP/Im,see the form below.);
• Bipolar constant current chopper control;
• Photocoupler isolated input/output;
• Adjustable drive current range from 0.5A/phase ~ 8A/phase
• Single power input, voltage range from AC60V~130V
•  The upmost pulse response frequence amounts to 200Kpps
• Protection of overvoltage、overheat and overcurrent
• Dimension:80*200*156m; Net Weight:2.0Kgs.

Caution

1. Do not reverse the power input,input voltage should not exceed AC130V.
2. Input logic should be 5V，otherwise it should connect a resistor.
3. O.H is malfunction indicator. Once the driver temperature exceeds 70°C,the current will be cut off automatically and the driver will resume working till the temperature drops to 50°C. If this happens,please install ventilation equipment.
4. Once over current (short circuit)/under voltage occur, LED O.C lights, please shut off power and check the electricity circuit to solve the problem, then restore power supply.
5. PWR is power indicator，it lights when power on.
6. Passing the origin or there is pulse output, TM LED lights.
