ASDA-B2
AL048:
Excessive encoder output error
Causes
Encoder error causes
abnormal encoder
output.
The output pulse
exceeds hardware
tolerance.
AL067:
Encoder temperature warning
Causes
Encoder temperature
is over 100°C.
AL083:
Servo Drive Outputs Excessive Current
Causes
UVW cable is short-
circuited
Wrong motor wiring
Analog signal (GND)
from servo drive is
interfered
Revision May, 2018
Checking Method
Exam error recording (P4-00 ~
P4-05) to check if encoder error also
occurs. (AL011, AL024, AL025,
AL026)
Check if following conditions occur:
P1-76 < Motor speed or
Motor speed
 P  
1 46 4
60
Checking Method
Check if the operating temperature is
excessive or the motor temperature
is over 85°C.
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 other signal.
Please refer to the corrective
actions of AL011, AL024,
AL025, and AL026.
Correctly set P1-76 and
P1-46:

Try to reduce operating
temperature.
Replace by new UVW cable
and avoid the metal
conductor being exposed so
as to eliminate 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.
