Part 9: Review on Replacement of Optional Peripheral Equipment

POINT
Three types of batteries are used to construct the absolute position detection
system: MR-BAT6V1SET battery, MR-BAT6V1BJ battery for junction battery
cable, and MR-BT6VCASE battery case. The use of the MR-BAT6V1BJ battery
for junction battery cable has the following characteristics distinctive from other
batteries.
• The encoder cable can be removed from the servo amplifier.
• A battery can be replaced with the control circuit power supply turned off.
If the encoder lost the absolute position data, always perform home position
setting before operation. The encoder will lose the absolute position data in the
following cases. In addition, the absolute position data may be erased if the
battery is used outside of the specification.
When using the MR-BAT6V1SET battery and the MR-BT6VCASE battery case
• Encoder cable is removed.
• A battery is replaced with the control circuit power supply turned off.
When using the MR-BAT6V1BJ battery for junction battery cable
• The connector and the cable are removed between the servo motor and the
battery.
• A battery is replaced in a procedure different from the procedure described in
the Instruction Manual.
A single MR-BT6VCASE battery case can retain the absolute position data of up
to eight axes of servo motors.
