Description
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.

estimated feedbacks.
Defines a load-side position offset. The resolution is
determined by parameter
Load-side position offset.
Defines how many bits are used for load position count within
one revolution. For example, with the setting of 16, the
position value is multiplied by 65536 for display in parameter
90.04 Load position.
Load position resolution.
Defines an initial position (or distance) for the position counter

Selects the source of the initial position integer value. When
the source selected by 90.67 Pos counter init cmd source
activates, the value selected in this parameter is assumed to
be the position of the load.
