78 Spd Ref TP RPM
Displays the value selected in Par 77 [Spd Ref TP Sel] in RPM. This display should only be
used if the selected value is floating point data.

79 Spd Ref TP Data
Displays the value selected in Par 77 [Spd Ref TP Sel]. This display should only be used if the
selected value is integer data.
Default:
Min/Max: 0

81 Spd Reg P Gain
Sets the proportional gain of the speed regulator. This value is automatically calculated
based on the bandwidth setting in
Par 90 [Spd Reg BW]. Proportional gain may be manually
adjusted by setting Par 90 [Spd Reg BW] to a value of zero. Units are (per unit torque) / (per
unit speed).
The maximum value for Par 81 [Spd Reg P Gain] = Par 90 [Spd Reg BW] *
Par 9 [Total Inertia]
Note: The Max. value was increased from 600.0000 for firmware version 3.01.
Default:
Min/Max: 20.0000

82 Spd Reg I Gain
Sets the integral gain of the speed regulator. This value is automatically calculated based on
the bandwidth setting in
Par 90 [Spd Reg BW]. Integral gain may be manually adjusted by
setting Par 90 [Spd Reg BW] to a value of zero. Units are (per unit torque/sec) / (per unit
speed).

84 SpdReg AntiBckup
By setting this parameter to 0.3, the drive will not over shoot to a step response. This
parameter has no affect on the drive's response to load changes. The recommended setting is
0.1000 to 0.5000.
Note: This parameter was changed to non-linkable for firmware version 3.01.
Default:
Min/Max: 0.0000
