Fault Cause
1. Abnormal memory
2. Not enough memory
There is a problem with the drive
1. The encoder of the driver board is
poorly connected or disconnected
2. The motor is damaged
3. The motherboard is damaged
1. The driver program is an old ver-
sion
2. Poor contact or broken wire of the
servo encoder
1. Voltage drop
2. The bus load is too heavy
3. Transformer failure
1. Excessive friction increases the
operating load
2. Insufficient power or improper
adjustment of internal parameters
1. Wiring error
2. The acceleration is too high
3. The grid voltage is too low
4. The driver power is low
5. The driver is shorted to ground

Solution
Spare alarm
Spare alarm
1. Maintenance memory
2. Expand memory or clear data
Update drive
Refer to E028 Error Handling Method
1. Check the encoder cable of the driver
board
2. Replace the motor
3. Replace the motherboard
1. Look at the screen "Internal Drive" - "Y
Servo" - "Version Number", 1 means the
old version needs to be returned to the
factory to update the program
2. Check the encoder cable
Refer to E408 Error Handling Method
1. Increase the voltage
2. Reduced load operation
3. Repair or replace the transformer
Spare alarm
Refer to E023 Error Handling Method
E026
Refer to Error Handling Method
1. Lubrication
2. Adjust the gain or adjust the parameters
Spare alarm
Refer to E029 Error Handling Method
Spare alarm
1. Check the line
2. Reduce acceleration
3. Check the input power
4. Choose the driver with large power level
5. Check whether the drive is short circuit-
ed to ground
