cause for the alarm. If the issue persists, please send your servo drive
back to the distributor or contact Delta.
(A) Make sure the servo motor is properly grounded and connect the
UVW connector (color green) to the servo drive heat sink.
(B) Make sure the encoder cable is separated from the power supply or
any high-current cables to avoid interference.
(C) Use shielded cable for the encoder. If issue persists, please send
your servo drive back to the distributor or contact Delta.
How to clear the

Cycle power on the servo drive.
AL029 Gray code error
Trigger condition
and causes
Absolute position error.
Checking methods
and corrective
actions

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.
