Description
Displays 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.
Displays 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.
Displays the revolutions of (multiturn) encoder 2 within
its value range (see parameter
width) as a raw measurement.
Note: This parameter is read-only.
Raw encoder 2 revolution count.
Displays the motor revolution count extension.
The counter is incremented when the position selected
by 90.41 Motor feedback selection
positive direction, and decremented in the negative
direction.
Note: This parameter is read-only.
Motor revolution count extension.
Displays the load revolution count extension.
The counter is incremented when the position selected
by 90.51 Load feedback selection
positive direction, and decremented in the negative
direction.
Note: This parameter is read-only.
Load revolution count extension.
