SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: If the output current (r0068) exceeds the maximum current (r0067), the frequency inverter is dynamically controlled
by reducing the output voltage. This parameter sets the proportional gain of this controller.
Note: See parameter P1340 for further information.
The Factory setting depends on inverter power.
Description: Integral time constant of the I_max voltage controller.
• P1341 = 0 : I_max controller disabled
• P1345 = 0 and P1346 > 0 : I_max voltage controller enhanced integral
• P1345 > 0 and P1346 > 0 : I_max voltage controller normal PI control
Note: See parameter P1340 for further information.
The Factory setting depends on inverter power.
Description: Sets whether voltage is built up smoothly during magnetization time (ON) or whether it simply jumps to boost volt-
age (OFF).
Values: 0: OFF
1: ON
Note: The settings for this parameter bring benefits and drawbacks:
• P1350 = 0: OFF (jump to boost voltage)
Benefit: flux is built up quickly
Drawback: motor may move
• P1350 = 1: ON (smooth voltage build-up)
Benefit: motor less likely to move
Drawback: flux build-up takes longer
