the function of protection.
AL031：Incorrect wiring of the motor power line U, V, W
Causes Checking Method Corrective Actions
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.)
Check if U, V, W of the motor is
incorrect connected or the
connection is breakdown.
Follow the user manual to correctly
wire U, V, and W and make sure it
is grounded.
AL034：Internal communication of the encoder is in error
Causes Checking Method Corrective Actions
Internal communication of
the encoder is in error
1. Internal communication error of
the absolute encoder
2. Internal error of other type of
encoder
Conduct the wiring of the battery
again and re-power on after that.
AL035：Encoder temperature exceeds the protective range
Causes Checking Method Corrective Actions
Encoder temperature
exceeds the protective
range, above 105℃
Check the setting: Set the value of
P0-02 to 120 to display the
temperature.
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.
AL040：Excessive deviation of full closed-loop position control
Causes Checking Method Corrective Actions
Excessive deviation of
full closed-loop position
control
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.
1. Increase the value of P1-73.
2. Check if the connection is
well connected.
AL041：Communication of linear scale is breakdown
Causes Checking Method Corrective Actions
The communication of
linear scale is breakdown
Check the communication of linear
scale.
Check the communication of linear
scale again.
