(3) Absolute position system errors (1200 to 1299)
These errors are detected at the absolute position system.
The error codes, causes, processing and corrective actions are shown in Table
1.10.

• A sum check error occurred
with the backup data in the
controller at the turning on
servo amplifier power
supply.
• Home position return was
not performed.
• CPU module battery error.
• Home position return started
but did not complete
normally.

• A communication error
between the servo amplifier
and encoder occurred at the

• Check the motor and encoder
cables and execute a home
position return again.
1203
• The amount of change in
encoder current value is
excessive during operation.
A continual check is
performed (both of servo
ON and OFF states) after
the servo amplifier power
has been turned ON.

A continual check is
performed (both of servo
ON and OFF states) after
the servo amplifier power
has been turned on.
