counter (page 51), and the diagram on page 585.
90.01 Motor speed for
control
Displays the estimated or measured motor speed that is used
for speed control, ie. final motor speed feedback selected by
parameter 90.41 Motor feedback selection and filtered by
90.42 Motor speed filter time.
In case measured feedback is selected, it is also scaled by the
motor gear function (90.43 Motor gear numerator and 90.44
Motor gear denominator).
This parameter is read-only.

-32768.00 …
32767.00 rpm
Motor speed used for control. See par.
46.01
90.02 Motor position Displays the motor position (within one revolution) received
from the source selected by parameter 90.41 Motor feedback
selection.
In case measured feedback is selected, it is also scaled by the
motor gear function (90.43 Motor gear numerator and 90.44
Motor gear denominator).
This parameter is read-only.

90.03 Load speed Displays the estimated or measured load speed that is used
for motor control, ie. final load speed feedback selected by
parameter 90.51 Load feedback selection and filtered by
parameter 90.52 Load speed filter time.
In case measured feedback is selected, it is also scaled by the
load gear function (90.53 Load gear numerator and 90.54
Load gear denominator).
In case motor feedback or estimated feedback is used, it is
inversely scaled by 90.61 Gear numerator and 90.62 Gear
denominator (ie. 90.62 divided by 90.61).
This parameter is read-only.

90.04 Load position Displays the load position received from the source selected
by parameter 90.51 Load feedback selection
. The value is
multiplied as specified by parameter 90.57 Load position
resolution.
In case measured feedback is selected, it is also scaled by the
load gear function (90.53 Load gear numerator and 90.54
Load gear denominator).
In case motor feedback or estimated feedback is used, it is
inversely scaled by 90.61 Gear numerator and 90.62 Gear
denominator (ie. 90.62 divided by 90.61).
An offset can be defined by 90.56 Load position offset.
This parameter is read-only.
