Chapter 10 Troubleshooting
AL030：Motor Crash Error
Causes
Motor Crash Error
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 100°C
(212°F).
Checking Method
1. Check if P1-57 is enabled.
2. Check if P1-57 is set too small
and the time of P1-58 is set too
short.
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
3. Incorrect wiring of the battery
cable.
4. Check the wiring.
5. Check the voltage.
Checking Method
Check the setting: set the value of
P0-02 to 120 to display the
temperature.
Corrective Actions
1. If it is enabled by mistake, please
set P1-57 to zero.
2. According to the actual torque
setting, if the value is set too
small, the alarm will be triggered
by mistake. However, if the value
is set too big, it will lose 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 then cycle power on the
system.
Corrective Actions
1. Improve heat dissipation or
reduce the loading of operation.
The temperature should be
lower than 100°C (212°F).
2. If the encoder's temperature is
higher than the motor's (more
than 30°C (86°F)). Please send
the motor back to the
distributors.
