392 Parameters
90.25 Encoder 2
revolutions raw Displays the revolutions of (multiturn) encoder 2 within its
value range (see parameter
93.14 Revolution data width ) as a
raw measurement.
This parameter is read-only.
-
0…16777215 Raw encoder 2 revolution count. -
90.26 Motor revolution
extension Displays 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.
This parameter is read-only.

90.27 Load revolution
extension Displays 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.
This parameter is read-only.

90.35 Pos counter status Status information related to the position counter function.
See section
Position counter (page 51 ).
This parameter is read-only.

No. Name/Value Description Def / FbEq16
Bit Name Value
0 Encoder 1
feedback 1 = Encoder 1 selected as load feedback source
1 Encoder 2
feedback 1 = Encoder 2 selected as load feedback source
2 Internal position
feedback 1 = Internal load position estimate selected as load feedback source
3 Motor feedback 1 = Motor feedback selected as load feedback source
4 Pos counter init
ready 0 = Position counter not initialized, or encoder feedback was lost.
Fresh counter initialization recommended.
1 = Position counter successfully initialized
5 Position counter re-
init disabled 1 = Position counter initialization is being prevented by par. 90.68
6 Position data
inaccurate 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.)
