AL.29
Encoder error 5
Alarm cause Checking method Corrective action
The move distance of the
absolute position revolution
number is out of range. Check if the absolute motor
operating revolution number
is within the range between -
32768 and +32767. Re-execute homing
and initialize absolute
coordinate according
to chapter 14
description.
AL.2A Absolute encoder error 1
Alarm cause Checking method Corrective action
Encoder backup battery
voltage is too low. Check whether the
battery voltage is
lower than 2. 45V
(TYP). Replace the battery, and then
re-execute homing and
initialize absolute coordinate
according to the description
of chapter 14 or PA29.
Poor contact or disconnection
of battery power supply circuit.
1.
Check the encoder
wiring.
2.
Check the
connection
between the
battery external
box and drive.
Connect or fix the connection
to make sure the encoder
power supply is normal, and
re-execute homing, and then
initialize absolute coordinate
according to the description
of chapter 14
AL.2B Absolute encoder error 2
Alarm cause Checking method Corrective action
The revolution count value of
absolute encoder is in error. Restart the motor and
check whether the alarm
recurs. If the issue persists,
send it back to the
distributor or
