1.4.3 Replacing the Batteries in a Separate Battery Case
Use the following procedure to replace the batteries in the battery case.
<1> Loosen the screws on the battery case and detach the cover.
<2> Replace the batteries in the case (pay attention to the polarity).
<3> Attach the cover to the battery case.
Battery case (with a cover)
Four A06B-6050-K061 batteries or
D-size alkaline dry cells
Four D-size alkaline dry cells (LR20) that are commercially available can be used as batteries. A set of four
A06B-6050-K061 batteries is optionally available from FANUC.
Replace all the four batteries with new ones. If old and new batteries are mixed, the absolute position
information in the absolute Pulsecoders may be lost.
1.4.4 Replacing the Battery Built into the Servo Amplifier
Use the following procedure to replace the special lithium battery.
<1> Detach the battery cover.
<2> Replace the special lithium battery.
<3> Attach the battery cover.
Purchase the battery from FANUC because it is not commercially available. It is therefore recommended that
you have a backup battery.
When the built-in battery is used, do not connect BATL (B3) of connector CXA2A/CXA2B. Also, do not
connect two or more batteries to the same BATL (B3) line. These connections are dangerous because
battery output voltages may be short-circuited, causing the batteries to overheat.
Install the battery in the servo amplifier in a direction that allows slack in the cable. If the battery cable is
under tension, a bad connection may occur.
If the +6 V pin and 0 V pin are short-circuited, the battery may overheat, blow out, or catch fire, or the
absolute position information in the absolute Pulsecoders may be lost.
When inserting the connector, align it to the connector pins.
[Connecting the battery]
The battery for the βiSV4 and βiSV20 series amplifiers is mounted in the battery case on the underside of each of the amplifiers.
The battery for the other βi series amplifiers and the αi series amplifiers is mounted at the front of each of the amplifiers.
