ASDA-A2
AL07D：Servo drive power is cycled before AL07C is cleared
Causes
AL07C occurs and is not
cleared before the power
is cycled on the servo
drive, then the motor
stops operating.
AL07E：Encoder clearing procedure error
Causes
The attempts to clear the
encoder exceed the limit.
AL083：Servo drive outputs excessive current
Causes
UVW cable is short-
circuited.
Wrong motor wiring
Analog signal (GND)
from servo drive is
interfered.

Checking Method
Check if the encoder parameter is
written.
Checking Method
If the issue persists, check the
communication quality with the
encoder.
Checking Method
Check the configuration of motor
power cable and connector cable.
See if the metal wire is exposed or
AWG is worn and causes short
circuit of UVW cable.
1. If applying non-standard power
cable recommended by Delta,
please check if the wiring
sequence of UVW cable is
correct.
2. Check if there is any problem of
lack phase when connecting
UVW from servo to motor
(unconnected or wrong
connection).
Check if the GND of analog signal is
misconnected to another ground
signal.

Corrective Actions
Use DI.ARST to clear the alarm.
Once this alarm is cleared, AL07C
occurs.
Corrective Actions
Use DI.ARST to clear the alarm.
Corrective Actions
Replace by new UVW cable and
avoid the metal conductor being
exposed so as to eliminate the
short circuit.
Please refer to the description of
wiring in Chapter 3 and conduct the
wiring again.
Please refer to Chapter 3 and
conduct the wiring again. GND of
analog signal cannot be grounded
with other signals.
