Fault Cause
1. Rotary motor alarm due to me-
chanical overload, etc.
2. The motor wire of the rotating mo-
tor is disconnected, the interface
is loose, and the connection line
between the motor and the driver
is faulty.
3.Rotary shaft driver is broken
4.The rotating motor is broken
Abnormal circuit of main board
1. The motor is broken or the motor
wire is damaged and short cir-
cuited
2. The motor is stuck
3. The driver board is damaged
4. The parameters are incorrect
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 discon-
nected
2. The motor is damaged
3. The motherboard is damaged
1. The driver program is an 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
– 58 –
Solution
1. Check if the machine is stuck
2.Chec k the corresponding wiring
3.Replace the flashing drive
4.Replace the motor
Overhaul the motherboard circuit
1. Check and replace the motor
2. Check the machinery
3. Replace the Y servo board
4. Reset or redirect parameters
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
