2.26 TorqLimAct (actual used torque limit)
Shows parameter number of the actual active torque limit:
0 =
0 no limitation active
1 =
2.19 TorqMaxAll (2.19) is active, includes current limits and field weakening
2 =
2.20 TorqMinAll (2.20) is active, includes current limits and field weakening
3 =
2.22 TorqUsedMax (2.22) selected torque limit is active
4 =
2.23 TorqUsedMin (2.23) selected torque limit is active
5 =
20.07 TorqMaxSPC (20.07) speed controller limit is active
6
= 20.08 TorqMinSPC (20.08) speed controller limit is active
7 =
20.09 TorqMaxTref (20.09) external reference limit is active
8 =
20.10 TorqMinTref (20.10) external reference limit is active

2.29 SpeedScaleAct (actual used speed scaling)
The value of
SpeedScaleAct (2.29) equals 20,000 internal speed units. Thus follows 20,000 speed units ==
M1SpeedScale (50.01
), in case M1SpeedScale (50.01) ≥ 10 or 20,000 speed units == maximum absolute
value of
M1SpeedMin (20.01) and M1SpeedMax (20.02), in case M1SpeedScale (50.01) < 10.
Mathematically speaking:
If
(50.01) ≥ 10 then 20,000 == (50.01) in rpm
If
(50.01) < 10 then 20,000 == Max [|(20.01)|, |(20.02)|] in rpm
