SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the proportional gain for the I_max voltage controller.
Dependency: Refer to: p1340
Note: The controller settings are also used in the current controller of the DC braking (refer to p1232).
Description: Sets the integral time for the I_max voltage controller.
Dependency: Refer to: p1340
Note: p1346 = 0: Integral time of the I_max voltage controller de-activated.
The controller settings are also used in the current controller of the DC braking (refer to p1232).
Description: Displays the economic factor determined for optimizing motor consumption.
Dependency: Refer to: p1335
Note: The value is only determined for operating modes with Economic (p1300 = 4, 7).
Description: Sets the maximum output frequency for resonance damping for U/f control.
Resonance damping is inactive above this output frequency.
Dependency: Refer to: p1338, p1339
Note: For p1349 = 0, the changeover limit is automatically set to 95 % of the rated motor frequency - however, to a max.
of 45 Hz.
