Product Introduction

• High performance, low price

• Equipped with 16-level constant microstepping with equal angle, higher resolution up to 40,000 pulses/rev

• Higher response frequency up to 500K pps

• When the stepping pulse stops for more than 100ms, the coil current is automatically reduced to half of the set current

• Optically isolated signal input/output

• Drive current adjustable from 1.2A/phase to 7.0A/phase in 16 steps

• Single power supply input, voltage range: AC 110-220V

• Power-off phase memory function (the system automatically memorizes the phase in case of accidental or manual power-off/shutdown)

• I/O signals, all input signals are optically isolated, compatible with signal levels from 5V to 24V

• Pulse smoothing function, enabling smoother low-speed motor operation, smoothing level adjustable

• Adjustable motor inductance to maximize stepper motor performance
  
  Electrical parameters
  

1. The input voltage must not exceed AC 270V;

2. The input pulse signal is effective on the falling edge; control via the rising edge requires setting the internal parameters of the driver;

3. When the driver temperature exceeds 75°C, the driver stops working and the fault indicator ALM lights up. The driver can resume operation only after the temperature drops to 50°C and the power is re-applied. If overheating protection is triggered, please install a heat sink;

4. Overcurrent (load short circuit) fault indicator ALM lights up. Please check the motor wiring and other short-circuit faults. After troubleshooting, reapply power to restore operation;

5. No motor fault indicator ALM lights up. Please check the motor wiring. After troubleshooting, reapply power to restore operation.
   

Self-test

Note: 1. When D6 is ON, the self-test switch is OFF.
2. When D6 is OFF, the self-test switch is ON.
