Velocity Feedback Testpoint Data HI
(32 bit)
[Vel Fdbk TP Hi]
This parameter contains the LOW part of
the 32 bit value of the internal location
selected by the Vel Fdbk
TP Sel Parameter, P145.
This parameter contains the HIGH part of
the 32 bit value of the internal location
selected by the Vel Fdbk TP Sel Parame-
ter, P145.
Velocity Feedback Testpoint Select
[Vel Fdbk TP Sel] Parameter Number 145
Parameter Type Sink
Display Units x
Drive Units None
Factory Default 0
Minimum Value 0
Maximum Value 16
Enums:
This parameter selects which internal loca-
tion of the velocity reference will become
the testpoint value shown in P143 & P144.
The value based upon the select will be
stored in the Vel Fdbk TP Low & Vel Fdbk
TP Hi parameter.

Velocity Feedback
[Vel Feedback] Parameter Number 146
Parameter Type Source
Display Units +/– x.x rpm
Drive Units 4096 @ Base Motor Speed
Factory Default +0.0 rpm
Minimum Value – 8 x Base Motor Speed
Maximum Value + 8 x Base Motor Speed
This parameter indicates the latest
measured motor velocity information from
a feedback device (Tach, encoder etc.)
The value is taken at the output of the
selectable feedback filters.
Scaled Velocity Feedback
[Scaled Vel Fdbk] Parameter Number 147
Parameter Type Source
Display Units +/– x
Drive Units None
Factory Default 0
Minimum Value –32767
Maximum Value +32767
This parameter is a rescaled version of ve-
locity feedback from parameter 146. The
inverse of either Velocity Scale Factor 1 or
2 is used.
