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
9 = 20.22 TorqGenMax (20.22) regenerating limit is active
10 = 20.24 IndepTorqMaxSPC (20.24) independent speed controller limit is active
11 = 20.25 IndepTorqMinSPC (20.25) independent speed controller limit is active
12 = 2.08 TorqRef1 (2.08) limits TorqRef2 (2.09), see also TorqSel (26.01)

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
