9.2 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 servo again and perform home positioning
according to the section 4.1.1.
Replace the battery (MR-J3BAT) while the control circuit power supply is on. If the
battery is replaced while the control circuit power supply is off, the absolute position
erase (25) will occur. Battery replacement using the cable for connecting battery
(MR-J3BTCBL03M) cannot be performed for the MR-J3-
B-RJ080W servo
amplifier.
Absolute position erase (25) will occur if the encoder cable is disconnected.
The MR-BTAS01 absolute position storage unit is required to configure the absolute position detection system
with the direct drive servo.
