MAINTENANCE1. METHOD OF REPLACING BATTERY
– The service life of the batteries is about two years if they are used in
a six–axis configuration with ai series servo motors and one year if
they are used in a six–axis configuration with a series servo motors.
FANUC recommends that you replace the batteries periodically
according to the battery service life.
– The battery unit consists of four R20 alkaline batteries. Commercial
batteries can be used in the battery unit. The optional battery offered
by FANUC is A06B–6050–K061.
1 Do not connect more than one battery to the same BATL
(B3) line. If the output voltage is different between the
batteries, they may be short–circuited, resulting in the
batteries becoming very hot.
2 Install the battery with correct polarity. If the battery is
installed with incorrect polarity, it may overheat, blow out, or
– If a low battery voltage or a battery voltage of 0 V is indicated by an APC
(absolute pulse coder) alarm, replace the battery(A06B–6073–K001).
If a battery voltage of 0 V is indicated, you need to make a zero point
