Additional Information
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
without the use of a battery cable for the absolute encoder.
