Table 6-56 Speed Loop Menu (3200) Parameters
Parameter ID Unit Default Min Max Description
Speed reg prop gain 3210 0.02 0.0 1.0 Speed PI regulator proportional gain term.*
Speed reg integral
gain
3220 0.046 0.0 1200.0 Speed PI regulator integral gain term.*
Speed reg Kf gain 3230 0.6 0.1 1.0 Allows a smooth variation of the speed regulator
from a simple PI (Kf = 1.0) to a double speed loop
(Kf = 0.5).
Speed 󹪝lter time
const
3240 0.0488 0.0 10.0 Time constant of the low pass 󹪝lter used on the
speed error.*
Droop in % @ FL cur‐
rent
3245 % 0.0 0.0 10.0 Desired speed droop in percent of rated speed at
full load current. Enter 0 to disable.
* Values are automatically calculated after Stage 2 auto-tuning.

3272 25.0 0.0 6000.0 Current PI regulator second integral gain term.
Prop gain during
brake
3280 0.16 0.0 5.0 Current PI regulator proportional during dual fre‐
quency braking.*
Integ gain during
brake
3290 9.6 0.0 6000.0 Current PI regulator integral gain term during dual

Secondary current loop gains that can switch quickly without interrupting the running
process based on the SOP 󹪞ag EnableSecondCurrentGains_O.
When EnableSecondGains_O = False --> gain set 3260 and 3270 is used (normal).
When EnableSecondGains_O = True --> gain set 3272 and 3273 is used instead.
