多Multi-turn data range
YAK/YBK absolute encoder motor single-turn resolution 8388608 (23bit), multi-turn number 65536,
the actual position value after the positive multi-turn data overflow changes from 2147418112 to -
2147418112, the negative multi-turn data overflow after the actual position value Changed from -
2147483648 to 2147483648, the motor rotation direction remains unchanged after overflow.

Multi-turn prohibition
Set encoder multi-turn disable (0x23400E) to 1, absolute encoder can be used as incremental
encoder without connecting battery. However, it should be noted that when the multi-turn
prohibition is turned on, the position of the encoder cannot be saved after the power is turned off.

How to use the battery
To install the battery box to the bottom of the drive, optional cables ENCDG-(4)-GU-BT5 and battery
box BAT-FD5 are required. You can also choose to purchase the integrated battery cable ENCDG-(4)-
GU-BT, and you can choose one of the two battery options.

Attention
⚫
After the communication encoder data is reset, the drive alarm will not be cleared directly. It is
necessary to clear the drive alarm through the control word or restart the drive.
⚫
After clearing the multi-turn fault, if the connection between the encoder wire and the motor end
is disconnected, the drive will have fault 000.4 again, and the encoder state needs to be reset.
⚫
After clearing the multi-turn data through the communication encoder data reset, the actual
position single-turn data will not be cleared at this time.
To reset the actual position, you need
to use the 35 homing mode to return to the origin.
