16. INDEXER POSITIONING OPERATION
16.10.2 Battery replacement procedure
WARNING
Before replacing a battery, turn off the main circuit power and wait for 15 minutes
or longer until the charge lamp turns off. Then, confirm that the voltage between
P( ) and N( ) is safe with a voltage tester and others. Otherwise, an electric
shock may occur. In addition, always confirm from the front of the servo amplifier
whether the charge lamp is off or not.
POINT
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical
parts, directly by hand.
(1) When replacing battery with the control circuit power on
POINT
Replacing battery with the control circuit power off will erase the absolute
position data.
Replacing battery with the control circuit power on will not erase the absolute position data. Refer to section
16.10.3 for mounting procedure of battery to the servo amplifier.
To replace battery with the control circuit power off, refer to (2) of this section.
(2) When replacing battery with the control circuit power off
Replacing battery with the control circuit power off will erase the absolute position data, but battery can be
replaced without erasing the absolute position data in the following procedure.
In this procedure, MR-J3BTCBL03M battery connection cable is required.
MR-J3BTCBL03M cannot be added after home position is set. Make sure to connect MR-J3BTCBL03M
between the servo amplifier and the encoder cable when connecting the encoder cable.
Refer to section 16.10.4 for the replacement procedure of the battery.
