Error description
Fault Cause
Solution
E401 (0x) Drive board hardware
protection
1. The motor is broken or the motor
wire is damaged and short circuit-
ed
2. The motor is stuck
3. The driver board is damaged
4. The parameters are incorrect
1. Check and replace the motor
2. Check the machinery
3. Replace the Y servo board
4. Reset or redirect parameters
Parameters for which (0x) is displayed
01: Main shaft motor
02: Hook motor
03: Upper rotating motor
04: Lower rotating motor
The same applies to the following
error items.
E402 (0x) Driver board HOC
Spare alarm
E403 (0x) Driver module AD mod-
ule initial calibration failure
Spare alarm
E404 (0x) Drive board parameter
storage error
1. Abnormal memory
2. Not enough memory
1. Maintenance memory
2. Expand memory or clear data
E405 (0x) Driver board system
parameters are abnormal
There is a problem with the drive
Update drive
E406 (0x) Driver board AD sam-
pling module is faulty
Refer to
Error Handling Method
E407 (0x) The driver board en-
coder is disconnected
1. The encoder of the driver board is
poorly connected or disconnected
2. The motor is damaged
3. The motherboard is damaged
1. Check the encoder cable of the driver
board
2. Replace the motor
3. Replace the motherboard
E408 (0x) Driver board encoder
AB interference
1. The driver program is an old ver-
sion
2. Poor contact or broken wire of the
servo encoder
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

(0x) Driver board encoder Z
interference
Refer to
Error Handling Method
E410 (0x) Driver board bus un-
dervoltage
1. Voltage drop
2. The bus load is too heavy
3. Transformer failure
1. Increase the voltage
2. Reduced load operation
3. Repair or replace the transformer
E411 (0x) Driver board bus over-
voltage
Spare alarm

overcurrent
Refer to
Error Handling Method
E413 (0x) Drive board motor
overload
Refer to
Error Handling Method
E414 (0x) Drive board drive over-
load
1. Excessive friction increases the
operating load
2. Insufficient power or improper
adjustment of internal parameters
1. Lubrication
2. Adjust the gain or adjust the parameters
E415 (0x) Driver board motor
overheating
Spare alarm
E416 (0x) Driver board driver
overheating
Refer to E029 Error Handling Method
