Fault Cause
1. The load is too heavy
2. The main shaft is mechanically
stuck
The main shaft 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
1. Abnormal startup
2. The motherboard is damaged
Abnormal memory chip
Parameter configuration error
1. Abnormal startup
2. The motherboard is damaged
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
1. The Y servo board program is the
old version
2. Poor contact or broken wire of the
servo encoder
1. Voltage drop
2. The bus load is too heavy
3. Transformer failure
1. The parameters are incorrect
2. The motor is stuck
3. The motor is broken or the motor
wire is damaged and short circuit-
ed
4. The power board is damaged
The Y axis is overloaded
Motor overload

Solution
1. Lighten the load
2. Check the machine
Check the main shaft 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
1. Restart
2. Replace the motherboard
Replace the chip
Check parameter configuration
1. Restart
2. Replace the motherboard
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
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
1. Increase the voltage
2. Reduced load operation
3. Repair or replace the transformer
Spare alarm
1. Reset or redirect parameters
2. Check the machinery
3. Check and replace the motor
4. Replace the power board
