Description
Displays the revolutions of (multiturn) encoder 2 within its
value range (see parameter
raw measurement.
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
direction, and decremented in the negative direction.
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
direction, and decremented in the negative direction.
This parameter is read-only.
Load revolution count extension.
Status information related to the position counter function.
See section Position counter
This parameter is read-only.
Value
1 = Encoder 1 selected as load feedback source
1 = Encoder 2 selected as load feedback source
1 = Internal load position estimate selected as load feedback source
1 = Motor feedback selected as load feedback source
0 = Position counter not initialized, or encoder feedback was lost.
Fresh counter initialization recommended.
1 = Position counter successfully initialized
1 = Position counter initialization is being prevented by par.
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.)
