Description
Load feedbacks are updated based on the speed and
position values read from encoder 1.
The values are scaled by the load gear function
gear numerator and 90.54 Load gear
The encoder is set up by the parameters in group
1 configuration.
Load feedbacks are updated based on the speed and
position values read from encoder 2.
The values are scaled by the load gear function
gear numerator and 90.54 Load gear
The encoder is set up by the parameters in group
2 configuration.
Calculated speed and position estimates are used. The
values are scaled from the motor side to the load side using
the inverted ratio between
Gear denominator (ie. 90.62
The source selected by parameter
selection for motor feedback is also used for load feedback.
Any difference between the motor and load speeds (and
positions) can be compensated by using the inverted ratio
between 90.61 Gear numerator
(ie. 90.62 divided by 90.61).

Parameters 90.53 and 90.54
the load (ie. driven equipment) speed and the encoder
feedback selected by parameter
selection. The gear can be used to correct a difference
between the load and encoder speeds for example if the
encoder is not mounted directly on the rotated machinery.
