Notice
1. Do not reverse the power supply, and the input voltage should not exceed DC36V. 2 Phase Stepper Driver The green indicator PWR is on when the QM Series driver is powered on.
2. When the fault indicator light of 2 Phase Stepper Driver QM Series Driver is on, please check the motor wiring and control signal line. If it is a motor wiring or other short-circuit fault, you need to power on again after troubleshooting.
3. 2 Phase Stepper Driver QM Series Driver's DIP switches SW1~SW6 need to be re-powered to take effect each time they are dialed.
