SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Displays the currently 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.
Description: Displays the torque limit to limit the speed controller output.
Index: [0] = Upper limit
[1] = Lower limit
Description: Displays the limit for the torque-generating current component using the stall calculation, the current limit of the
power unit as well as the parameterization in p0640.
Index: [0] = Upper limit
[1] = Lower limit
Description: Sets the signal source for the scaling of the upper torque limiting to limit the speed controller output without taking
into account the current and power limits.
Description: Sets the signal source for the scaling of the lower torque limiting to limit the speed controller output without taking
into account the current and power limits.
