Parameter 20 – Velocity Feedback (Vel Feedback) *
The unfiltered motor velocity is displayed through this parameter.
Parameter Type:
View only, all levels
Minimum Value:
–8000 rpm
Maximum Value:
+8000 rpm
Parameter 21 – Filtered Velocity Feedback (Filtrd Vel Fb) *
The filtered velocity feedback which is output by the lead/lag filter is
supplied by this parameter. The bandwidth of the filter is specified by
parameter 186 and the filter gain is specified by parameter 185.
Parameter Type:
View only in Maintenance level
Minimum Value:
–8000 rpm
Maximum Value:
+8000 rpm
Parameter 22 – Average Motor Velocity (Average Mtr Vel) *
This parameter supplies the average velocity feedback which is output by
the single pole low pass filter. The bandwidth of the filter is specified by
parameter 184.
Parameter Type:
View only in Maintenance level
Minimum Value:
–8000 rpm
Maximum Value:
+8000 rpm
Parameter 23 – Resolver Turns *
The number of resolver electrical turns is supplied by this parameter. When
these values reach maximum, the value drops to zero and begins to again
count up and down.
Parameter Type:
View only in Maintenance level
Minimum Value:
–32768
Maximum Value:
+32767
Parameter 24 – Resolver Position Feedback (Resolver Posn) *
This parameter supplies the position feedback count. 65,535 represents the
counts per 1/2 motor revolution.
Parameter Type:
View only in Maintenance level
Minimum Value:
0
Maximum Value:

View only in Maintenance level
Minimum Value:
–8000 rpm
Maximum Value:
+8000 rpm
Parameter 33 – Proportional Velocity Error (Prop Vel Error) *
This is the error between the Final Velocity Command (parameter 19) and
the Filtered Velocity Command (parameter 21).
Parameter Type:
View only in Maintenance level
Minimum Value:
–8000 rpm
Maximum Value:
