81 Spd Reg P Gain
Sets the proportional gain of the speed regulator. It's value is
automatically calculated based on the bandwidth setting in
parameter 90 [Spd Reg BW]. Proportional gain may be
manually adjusted by setting parameter 90 to a value of zero.
Units are (per unit torque) / (per unit speed). Default:

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

Regulator
84 SpdReg AntiBckup
This term modifies the drive's response to the speed reference.
With the value minimized, the drive will follow the reference
very closely, minimizing error, which is desirable for most
process applications. However, it will exhibit some over-shoot
and under-shoot. Increasing the value of this term decreases
the over-shoot and under-shoot, which is desirable where
back-up can not be tolerated. However, this tends to increase
the following error. This parameter has no affect on the drive's
response to load changes. Default:
