Current limit minimum torque-generating current / Isq_min
Access level: 4
Calculated: -
Data type: FloatingPoint32
Can be changed: -
Scaling: p2002
Dynamic index: -
Unit group: 6_2
Unit selection: p0505
Function diagram: 6640, 6710
Min:
- [Arms]
Max:
- [Arms]
Factory setting:
- [Arms]
Description:
Displays the minimum limit for the torque-generating current component.
Index 0 indicates the signal limited by the Vdc controller.
Index:
[0] = Limited
[1] = Unlimited
r1538
CO: Upper effective torque limit / M_max upper eff
Access level: 2
Calculated: -
Data type: FloatingPoint32
Can be changed: -
Scaling: p2003
Dynamic index: -
Unit group: 7_1
Unit selection: p0505
Function diagram: 6020, 6640
Min:
- [Nm]
Max:
- [Nm]
Factory setting:
- [Nm]
Description:
Display and connector output for the actual effective upper torque limit.
Note
The effective upper torque limit is reduced with respect to the selected upper torque limit p1520, if the current limit
p0640 is reduced or the rated magnetizing current of the induction motor p0320 is increased.
This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
r1539
CO: Lower effective torque limit / M_max lower eff
Access level: 2
Calculated: -
Data type: FloatingPoint32
Can be changed: -
Scaling: p2003
Dynamic index: -
Unit group: 7_1
Unit selection: p0505
Function diagram: 6020, 6640
Min:
- [Nm]
Max:
- [Nm]
Factory setting:
- [Nm]
Description:
Display and connector output for the actual effective lower torque limit.
Note
The effective lower torque limit is reduced with respect to the selected lower torque limit p1521, if the current limit p0640
is reduced or the rated magnetizing current of the induction motor p0320 is increased.
This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
