Description
Displays the 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
Load gear
denominator).
In case motor feedback or estimated feedback is used, it is
inversely scaled by
90.61 Gear numerator
denominator
(ie.
90.62
divided by 90.61).
An offset can be defined by
This parameter is read-only.
Load position.
Displays the scaled load position in decimal format. The
position is relative to the initial position set by parameters
90.65
and 90.66.
The number of decimal places is defined by parameter

Note: This is a floating point parameter, and the accuracy is
compromised near the ends of the range. Consider using
