Chapter 10 Troubleshooting
AL031：Incorrect wiring of the motor power line U, V, W
Causes
The wiring of U, V, W of
the motor is incorrect
connected or the
connection is breakdown.
(Function of connection
detection can be enabled
or disabled via P2-65 Bit
9. Its default setting is to
disable the function.)
AL034：Internal communication of the encoder is in error
Causes
Internal communication of
the encoder is in error
AL035：Encoder temperature exceeds the protective range
Causes
Encoder temperature
exceeds the protective
range, above 105℃
AL040：Excessive deviation of full closed-loop position control
Causes
Excessive deviation of
full closed-loop position
control
AL041：Communication of linear scale is breakdown
Causes
The communication of
linear scale is breakdown
Revision February, 2017
Checking Method
Check if U, V, W of the motor is
incorrect connected or the
connection is breakdown.
Checking Method
1. Internal communication error of
the absolute encoder
2. Internal error of other type of
encoder
Checking Method
Check the setting: Set the value of
P0-02 to 120 to display the
temperature.
Checking Method
1. Check if P1-73 is set too small.
2. Check if the connector is loose
or there is any connection
problem of other mechanism.
Checking Method
Check the communication of linear
scale.
the function of protection.
Corrective Actions
Follow the user manual to correctly
wire U, V, and W and make sure it
is grounded.
Corrective Actions
Conduct the wiring of the battery
again and re-power on after that.
Corrective Actions
1. Improve heat dissipation or
reduce the loading of operation.
The temperature should be
lower than 100℃.
2. If the encoder's temperature is
higher than the motor's (more
than 30 degree). Please send
the motor back to the
distributors.
Corrective Actions
1. Increase the value of P1-73.
2. Check if the connection is
well connected.
Corrective Actions
Check the communication of linear
scale again.
