Note: Multi-rotation Data Backup
• The multi-rotation data will be lost if the battery cable connector is disconnected at the
motor when connecting the battery cable for the absolute encoder and battery.
• The multi-rotation data will be lost if CN2 is disconnected when connecting the battery
to CN1.
