Fault Cause
1. The parameters are incorrect.
2. The motor is stuck
3. The motor is broken or the motor
wire is broken and short circuited
4. Power board is broken
1. Poor encoder wiring
2. The encoder is damaged
1. The load is too heavy
2. The spindle is mechanically stuck
The spindle load is too large
1. The motor is broken or the motor
wire is broken and short circuited
2. The motor is stuck
3. Y servo board is broken
4. The parameters are incorrect
Abnormal memory chip
Parameter configuration error
1. Y servo encoder has poor contact
or disconnection
2. Y servo motor is broken
3. Y servo board is broken
1. The Y servo board program is the
old version
2. Poor contact or broken wire of the
servo encoder
Motor overload

Solution
1. Reset or redirect parameters
2. Check the machinery
3. Check and replace the motor
4. Replace the power board
1. Check the motor encoder wiring
2. Replace the spindle motor
1. Lighten the load
2. Check the machine
Check the spindle mechanical structure for
problems
1. Check and replace the motor
2. Check the machinery
3. Replace Y servo board
4. Reset or redirect parameters
Spare alarm

Refer to Error Handling Method
Replace the chip
Check parameter configuration
E028
Refer to Error Handling Method
1. Check the Y servo encoder line
2. Replace Y servo motor
3. Replace Y servo board
1. Look at the screen "Internal Drive" - "Y
"Version Number", 1 means the old ver-
sion needs to be returned to the factory
to update the program
2. Check the encoder cable
