- / int32Displays the revolution count extension for encoder 2.
With a single-turn encoder, the counter is incremented
when encoder position (parameter 90.21) wraps around
in the positive direction, and decremented in the
negative direction.
With a multiturn encoder, the counter is incremented
when the revolutions count (parameter 90.22) exceeds
the value range in the positive direction, and
decremented in the negative direction.
Note: This parameter is read-only.

- / 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.

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.

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.
