AL048:
Excessive encoder output error
Causes
Checking Method
Corrective Actions
Encoder error causes
abnormal encoder
output.
Exam error recording (P4-00 ~
P4-05) to check if encoder error also
occurs. (AL011, AL024, AL025,
AL026)
Please refer to the corrective
actions of AL011, AL024,
AL025, and AL026.
The output pulse
exceeds hardware
tolerance.
Check if following conditions occur:

AL067:
Encoder temperature warning
Causes
Checking Method
Corrective Actions
Encoder temperature
is over 100°C.
Check if the operating temperature is
excessive or the motor temperature
is over 85°C.
Try to reduce operating
temperature.
AL083:
Servo Drive Outputs Excessive Current
Causes
Checking Method
Corrective Actions
UVW cable is short-
circuited
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.
Replace by new UVW cable
and avoid the metal
conductor being exposed so
as to eliminate short-circuit.
Wrong motor wiring
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)
Please refer to the
description of wiring in
Chapter 3 and conduct the
wiring again.
Analog signal (GND)
from servo drive is
interfered
Check if the GND of analog signal is
misconnected to other signal.
Please refer to Chapter 3 and
conduct the wiring again.
GND of analog signal cannot
be grounded with other
signals.
