14.8.2 Absolute position storage unit MR-BTAS01
POINT
Replacing the MR-BTAS01 absolute position storage unit will erase the absolute
position. Start up the direct drive motor again and perform home positioning
according to section 14.4.1.
Replacing battery unit (MR-BTCASE MR-BAT 8) should be during control circuit
power supply on.
Replacing the unit during control circuit power supply off will cause Absolute
position erased (25.1).
Absolute position erased (25.1) will occur if the encoder cable is disconnected.
To configure the absolute position detection system by using the direct drive motor, the battery unit (MR-
BTCASE MR-BAT 8) and the absolute position storage unit MR-BTAS01 are required.
