Characteristic:

Featuring 16 levels of equal angle constant moment subdivision, with a maximum resolution of 60000 steps per revolution

The maximum response frequency can reach 200Kpps

When the step pulse stops for more than 1.5 seconds, the coil current automatically decreases to half of the set current

Optoelectronic isolation signal input/output

The driving current is adjustable from 1.3A/phase to 7.0A/phase in 16 levels

Single power input, voltage range: AC80V~290V

Phase memory function (note: after the input stops for more than 3 seconds, the driver automatically remembers the current motor phase, and when it is powered on again or the MF signal changes from low level to high level, the driver automatically restores the motor phase).

Current setting

The operating current of the driver is set by terminals D1-D4, and the operating current is the normal output current setting switch (see the table below for details)

Subdivision settings

The subdivision of the driver is set by terminals D5-D8, with a total of 16 levels. D9 and D10 are functional settings. Attached Table: Subtraction (Pulse/Revolution)

Note: Customization of fine scores can be made according to customer requirements!

Wiring precautions:

1. When the input voltage is lower than AC80V and higher than AC290V, the driver will automatically protect

2. The input control signal level is 5V. When it is higher than 5V, a current limiting resistor needs to be connected, and the driver comes with a 24V signal interface

3. The falling edge of the input pulse signal is effective

4. The cooling fan of the drive only starts working when the temperature of the drive exceeds 48 degrees Celsius

5. When the temperature of the drive exceeds 80 degrees Celsius, the drive stops working and the fault indicator light ALM lights up. Until the temperature of the drive drops to 50 degrees Celsius, the drive needs to be powered on again to resume operation. If overheating protection occurs, please install a radiator

6. The overcurrent (load short circuit) fault indicator light ALM is on. Please check the motor wiring and other short circuit faults. After troubleshooting, it is necessary to power on again to restore

7. No motor fault indicator light ALM is on. Please check the motor wiring. After troubleshooting, power on again to restore

Corresponding fault symptoms (excluding power light and POW light)

1. Module overcurrent: single red light (ALM light) always on

2. Drive overheating: The red light (ALM light) and two green lights (PU light and DR light) alternate on

3. Undervoltage: The red light (ALM light) and DR light are both on

4. Overvoltage: Red light (ALM light) flashing fast
