5.4 MR-J3W series Battery
5.4.1 MR-BTCASE battery case and MR-BAT battery
POINT
Refer to "Servo Amplifier Instruction Manual" for battery transportation and the
new EU Battery Directive.
Always install eight MR-BAT batteries to an MR-BTCASE battery case.
These are used to configure an absolute position detection system.
An MR-BTCASE battery case is a case
that stores eight MR-BAT batteries by connector connections. An MR-BTCASE battery case can be used by
four MR-J3W-B servo amplifiers (eight axes) at maximum. To connect an MR-BTCASE battery case to a
servo amplifier, the MR-J3BT1CBL_M battery cable is required. To connect multiple servo amplifiers to an
MR-BTCASE battery case, use the MR-J3BT2CBL_M junction battery cable. When using an MR-J3W-B
servo amplifier in the incremental system, MR-BTCASE and MR-BAT are not required.
Battery backup time (battery life without charging) is 30,000 hours for one servo amplifier (two axes) and
10,000 hours for four servo amplifiers (eight axes).
Refer to servo amplifier instruction manual for the usage.
