Siemens SINAMICS G120X - CO: Lower Effective Torque Limit; M_Max Lower Eff; CO: Torque Limit for Speed Controller Output; M_Max Outp N_Ctrl; CO: Upper Effective Torque Limit; M_Max Upper Eff; Current Limit Minimum Torque-Generating Current; Isq_Min

r1537[0...1] 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.
r1547[0...1] CO: Torque limit for speed controller output / M_max outp n_ctrl
Access level: 3 Calculated: - Data type: FloatingPoint32

Max:
- [Nm]
Factory setting:
- [Nm]
Description: Displays the torque limit to limit the speed controller output.
Index: [0] = Upper limit
[1] = Lower limit
