No.
- / uint32Displays the raw measurement data of encoder 2 position
(within one revolution) as a 24-bit unsigned integer received
from the encoder interface.
Note: This parameter is read-only.

- / -Raw encoder 2 position within one revolution.0...16777215
- / uint32Displays the revolutions of (multiturn) encoder 2 within its
value range (see parameter 93.14 Revolution data width)
as a raw measurement.
Note: This parameter is read-only.

- / -Raw encoder 2 revolution count.0...16777215
- / int32Displays the motor revolution count extension.
The counter is incremented when the position selected by
90.41 Motor feedback selection wraps around in the
positive direction, and decremented in the negative
direction.
Note: This parameter is read-only.

- / int32Displays the load revolution count extension.
The counter is incremented when the position selected by
90.51 Load feedback selection wraps around in the positive
direction, and decremented in the negative direction.
Note: This parameter is read-only.

1 = Encoder feedback intermittent or lost. (If the drive is
running, estimated position is used whenever encoder
feedback is unavailable. If the drive is in stopped state,
position counting will continue based on encoder data after
the connection is restored.)
