Product Features:

● Single power supply input, voltage range: AC110V～220V
● Drive current 1.2A/phase to 6.5A/phase, 16 adjustable levels
● 16 levels of equal-angle constant torque subdivision, higher resolution up to 60000 steps/revolution, other subdivisions can be customized
● Maximum response frequency up to 150Kpps
● When the stepping pulse stops for more than 100ms, the coil current is automatically reduced to half of the set current, effectively reducing motor heating.
● Optocoupler isolation for interface signals, signal level 5V～24V compatible
● Internal strong and weak current optocoupler isolation
● Operating temperature: -40℃～85℃
● Applicable motors: Three-phase 86, 110, 130 series high-voltage motors
● Phase memory function (Note: After the input stops for more than 3 seconds, the driver automatically memorizes the current motor phase. When power is reapplied or the MF signal changes from low to high level, the driver automatically restores the motor phase).
● With motor inductance adjustment function, allowing the motor to perform at its best.

Precautions

1. The input voltage is 220V. If the voltage exceeds 260V or is unstable, please use an isolation transformer or voltage regulator.

2. The input pulse signal is active on the falling edge. If a rising edge active signal is required, please inform us in advance, and our company can make the corresponding modification.

3. When the temperature exceeds 75 degrees Celsius, the driver will stop working and the fault indicator (ALM) will light up. The driver requires a power cycle to resume operation only after the temperature drops to 50 degrees Celsius. If overheating protection is triggered, please install a heatsink.

4. If the overcurrent (load short circuit) fault indicator (ALM) lights up, please check the motor wiring and other potential short circuits. After resolving the issue, a power cycle is required to restore operation.

5. If the no-motor fault indicator (ALM) lights up, please check the motor wiring. After resolving the issue, a power cycle is required to restore operation.
