Checking methods
and corrective
actions
Check if the motor power cable (U, V, W, GND) is firmly connected. Please
connect wiring and ground properly by following the instructions in this user
manual.
How to clear the
alarm?
Cycle power on the servo drive.
AL034 Encoder internal communication error
Trigger condition
and causes
Condition:
1. Internal communication error for the absolute type encoder.
2. Internal error for the other type of encoder.
Cause: encoder internal communication error.
Checking methods
and corrective
actions
1. Check the battery wiring. Then wire it again and cycle power on the
system.
2. Internal communication error for the absolute type encoder occurs.
Please replace the motor.
How to clear the
alarm?
Cycle power on the servo drive.
AL035 Encoder temperature exceeds the protective range
Trigger condition
and causes
Condition: encoder temperature is over the maximum of 100
℃
.
Cause: encoder temperature is over 100
℃
.
Checking methods
and corrective
actions
Set P0.002 to 120d in order to read the temperature and check if it is below
100
℃
. If the encoder temperature is higher than 100
℃
, please improve the
heat dissipation or reduce the operating load. If the temperature difference
between the motor and the displayed temperature value is over 30
℃
,
please send the motor back to the distributor.
How to clear the
alarm?
After the temperature detector shows a temperature below 100
℃
, please
cycle power on the servo drive.
AL040 Excessive deviation of full closed-loop position control
Trigger condition
and causes
Excessive deviation of full closed-loop position control
Checking methods
and corrective
actions
1. Check the value for P1.073. If the value is too low, please set a higher
value.
2. Make sure the connector is firmly connected and there is no problem in
connecting the mechanism.
