NOTE
The absolute Pulsecoder of the αi/αis/βis (β0.4is to
β22is) 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. If battery
replacement takes 10 minutes or more, the power
must remain turned on.
CAUTION
1 When replacing the battery, be careful not to touch
bare metal parts in the panel. In particular, be
careful not to touch any high-voltage circuits due to
the electric shock hazard.
2 Before replacing the battery, make sure the DC link
charge LED is off. Otherwise, an electric shock may
be received.
3 Be sure to use the specified battery. If another type
of battery is used, it may overheat, blow out, or
catch fire.
4 Install the battery with correct polarity. If the battery
is installed with incorrect polarity, it may overheat,
blow out, or catch fire. Or, absolute position
information in absolute Pulsecoders may be lost.
5 During attachment of the battery, insert the
factory-attached protection socket into the CX5X or
CX5Y connector, whichever is not used. If the +6 V
pin and 0 V pin are short-circuited, the battery may
overheat, blow out, or catch fire. Or, absolute
position information in absolute Pulsecoders may
be lost.
