Siemens SINAMICS G120XA - CO: I_Max Controller Frequency Output; I_Max_Ctrl F_Outp; I_Max Controller Voltage Output; I_Max_Ctrl U_Outp; I_Max Frequency Controller Integral Time; I_Max_Ctrl Tn; I_Max Voltage Controller Proportional Gain; I_Max_U_Ctrl Kp

NOTICE
When deactivating the I_max controller, the following must be carefully observed:
When the maximum current (r0067) is exceeded, the output current is no longer reduced. The drive is switched off
when the overcurrent limits are exceeded.
Note
The I_max limiting controller becomes ineffective if the ramp-function generator is deactivated with p1122 = 1.
p1341 = 0:
I_max frequency controller deactivated and I_max voltage controller activated over the complete speed range.
p1341[0...n] I_max frequency controller integral time / I_max_ctrl Tn
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6300, 6850
Min:
0.000 [s]
Max:
50.000 [s]
Factory setting:
0.300 [s]
Description: Sets the integral time for the I_max frequency controller.
Dependency: See also: p1340
Note
When p1341 = 0, the current limiting controller influencing the frequency is deactivated and only the current limiting
controller influencing the output voltage remains active (p1345, p1346).
In the case of power units with regenerative feedback (PM250, PM260), current limitation control for a regenerative
load is always implemented by influencing the frequency. This current limiting function is deactivated with p1340 =
p1341 = 0.
