Methods to Clear Driver Alarms
When a drive experiences faults such as overvoltage or overcurrent, it automatically stops working, and the motor comes to a halt. The drive's red light may flash or remain steady. To clear the drive alarm state, the following methods can be employed (excluding troubleshooting):
1. T-Series Open/Closed-Loop Drives, RS-Series Open/Closed-Loop Drives, AI-Series Open-Loop Drives, etc.
For these drives, except for the "position error (red light flashing 7 times)" fault, which can be cleared by disabling the drive (ENA), all other alarm faults can only be resolved by power cycling the drive.
2. Y-Series Open/Closed-Loop Drives
Different types of faults in this series of drives can be cleared using different methods. Please refer to the table below for specific instructions:
Failure Code | Fault Information | Alarm | Reset |
|---|---|---|---|
Err1: 0x01 | Overcurrent or phase-to-phase short circuit | Blinking once continuously | Release/Power off reset |
Err2: 0x02 | High power supply voltage | Blinking twice continuously | Lock machine/Voltage returns to normal and can automatically recover |
Err3: 0x03 | Low power supply voltage | Blinking three times continuously | Release/Voltage returns to normal and can automatically recover |
Err5: 0x05 | Deviation exceeds limit | Blinking five times continuously | Release/Power off reset or clear the deviation alarm |
Err4: 0x04 | Brake abnormality | Blinking four times continuously |

3. DBLS/BLD Series Brushless Drives
When a brushless drive alarms, the alarm can only be cleared by resetting the enable terminal (i.e., disconnecting EN from GND) or by disconnecting the power supply.
