PERIODIC MAINTENANCE OF BATTERY FOR THE
ABSOLUTE PULSECODER
New Jan.28.2005
This technical report updates the item of the battery of a
maintenance manual (B-65285JA/03) for the new battery.
Since the battery of the old specification became the object
which must be treated as a dangerous object by the U.N.
advice at the time of transportation, the battery was changed
into the new battery out of a dangerous object.

2. Changed part
(1) Change of specification
(a). Battery : A06B-6073-K001 → A06B-6114-K504
(b). Battery Case : A06B-6114-K500 → A06B-6114-K505
(c). Battery Case : A06B-6114-K501 → A06B-6114-K506
Above-mentioned (c) is a battery case for SVM1-360i, SVM1-180HVi, SVM1-360HVi, and (b) is a
battery case for the other SVM.
(2) Change of a life span standard
In case of α series Servo Motor : One year / 3axses -> Half a year / 3axses
In case of αis/αi series Servo Motor : Two years / 3axses -> One year / 3axses

PERIODIC MAINTENANCE OF BATTERY FOR THE ABSOLUTE PULSECODER
1. BATTERY FOR THE ABSOLUTE PULSECODER
The battery unit for the absolute Pulsecoder can be connected using [Connection scheme 1] and
[Connection scheme 2] explained below. Refer to Subsection 9.3.2.6, "Battery" in "FANUC
SERVO AMPLIFIER αi series Descriptions (B-63282EN)" for details.

Pulsecoder) alarm, replace the battery.
If a battery voltage of 0 V is indicated, you need to make a zero point return.
- The absolute Pulsecoder of the αis/αi series servo motor is incorporated with a backup
capacitor as standard. This backup capacitor enables an absolute position detection to be
continued for about 10 minutes. Therefore, no zero point return need be performed if the
time during which servo amplifier power is kept off for battery replacement is within 10
minutes.
On the contrary, the absolute Pulsecoder of the standard α series servo motor is not
incorporated with a backup capacitor. Be careful when replacing the battery for this
Pulsecoder. See [Caution No. 1 for battery replacement] at the end of this section for
details.
- The service life of the batteries is about two years if they are used in a six-axis
configuration with αis/αi series servo motors and one year if they are used in a six-axis
configuration with α 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.
WARNING
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 catch fire.
