Absolute pulse coder battery replacement
Only those personnel who have received approved safety and maintenance training may perform
this work.
When replacing the batteries, be careful not to touch the high–voltage circuits (marked
and
fitted with an insulating cover).
Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock
hazard.
NOTE
The absolute pulse coder uses batteries to preserve its absolute position.
If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator’s panel
or screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
absolute position data held by the pulse coder will be lost.
Refer to the FANUC Servo Amplifier α series Maintenance Manual or FANUC Servo Motor β series
Maintenance Manual for details of the battery replacement procedure.
