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 CodeFault InformationAlarmReset
Err1: 0x01Overcurrent or phase-to-phase short circuitBlinking once continuouslyRelease/Power off reset
Err2: 0x02High power supply voltageBlinking twice continuouslyLock machine/Voltage returns to normal and can automatically recover
Err3: 0x03Low power supply voltageBlinking three times continuouslyRelease/Voltage returns to normal and can automatically recover
Err5: 0x05Deviation exceeds limitBlinking five times continuouslyRelease/Power off reset or clear the deviation alarm
Err4: 0x04Brake abnormalityBlinking four times continuously1. Check the brake line. 2. Check if the load weight is overloaded. 3. Power off and power on again.

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.
