AL030 Motor crash error
Trigger condition
and causes
Condition: when the motor hits the device, the torque reaches the value of
P1.057 and lasts for the time set by P1.058.
Causes:
1. Check if the function of motor crash protection (P1.057) is enabled. If
so, please set P1.057 to 0.
2. Check if the value of P1.057 is set too low and the time set by P1.058 is
too short. Please set P1.057 according to the actual torque. Incorrect
values might inadvertently trigger the signal or lose the protection
function.
Checking methods
and corrective
actions
Cycle power on the servo drive to operate the motor and check if the alarm
occurs again. If the issue persists, please replace the encoder.
