20.08 TorqMinSPC (minimum torque speed controller)
Minimum torque limit - in percent of MotNomTorque (4.23) - at the output of the speed controller.
−
TorqRef2 (2.09)
Notes:
−
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
current limits, field weakening). The limit with the largest value is valid.
−
Do not change the default setting of TorqMinSPC (20.08) for 2-Q drives, because M1CurLimBrdg2 (20.13)
is internally set to 0 % if QuadrantType (4.15) = BlockBridge2 (2-Q drive).
Int. Scaling: 100 == 1 % Type: SI Volatile: N

20.09 TorqMaxTref (maximum torque of torque reference A/B)
Maximum torque limit - in percent of MotNomTorque (4.23) - for external references:
−
TorqRefA (25.01)
−
TorqRefB (25.04)
Note:
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
current limits, field weakening). The limit with the smallest value is valid.

20.10 TorqMinTref (minimum torque of torque reference A/B)
Minimum torque limit - in percent of MotNomTorque (4.23) - for external references:
−
TorqRefA (25.01)
−
TorqRefB (25.04)
Note:
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,

20.12 M1CurLimBrdg1 (current limit of bridge 1)
Current limit bridge 1 in percent of M1NomCur (99.03).
Notes:
−
Setting M1CurLimBrdg1 (20.12) to 0 % disables bridge 1.
−
The used current limit depends also on the converter's actual limitation situation (e.g. torque limits, other
current limits, field weakening). The limit with the smallest value is valid.

20.13 M1CurLimBrdg2 (current limit of bridge 2)
Current limit bridge 2 in percent of M1NomCur (99.03).
Notes:
−
Setting M1CurLimBrdg2 (20.13) to 0 % disables bridge 2.
−
The used current limit depends also on the converter's actual limitation situation (e.g. torque limits, other
current limits, field weakening). The limit with the largest value is valid.
−
M1CurLimBrdg2 (20.13) is internally set to 0 % if QuadrantType (4.15) = BlockBridge2 (2-Q drive). Thus,
do not change the default setting for 2-Q drives.
