Description
Motor and load feedback configuration.
See also section Encoder support
counter (page 92),and the diagram on page 647.
Displays estimated or measured motor speed that is used
for motor control, i.e. final motor speed feedback selected by
parameter 90.41 Motor feedback selection
90.42 Motor speed filter
In case measured feedback is selected, it is also scaled by
the motor gear function
90.44 Motor gear denominator).
This parameter is read-only.
Motor speed used for control.
Displays motor position (within one revolution) received from
the source selected by parameter
selection.
In case measured feedback is selected, it is also scaled by
the motor gear function
90.44 Motor gear denominator).
This parameter is read-only.
Motor position.
Displays estimated or measured load speed that is used for
motor control, i.e. final load speed feedback selected by
parameter 90.51 Load feedback selection
parameter 90.52 Load speed filter
In case measured feedback is selected, it is also scaled by
the load gear function (90.53 Load gear numerator
90.54 Load gear denominator).
In case motor feedback or estimated feedback is used, it is
inversely scaled by 90.61 Gear numerator
denominator (that is 90.62
This parameter is read-only.
Load speed.
Displays load position received from the source selected by
parameter 90.51 Load feedback
multiplied as specified by parameter
resolution.
In case measured feedback is selected, it is also scaled by
the load gear function (90.53 Load gear numerator
90.54 Load gear denominator).
In case motor feedback or estimated feedback is used, it is
inversely scaled by 90.61 Gear numerator
denominator (i.e. 90.62
