Co: U/F Control Eco Factor Actual Value / U/F Eco Fac Act V; U/F Mode Resonance Damping Maximum Frequency / Uf Res_Damp F_Max; U/F Control Soft Start / U/F Soft Start - Siemens SINAMICS G150 Manual

Note: The controller settings are also used in the current controller of the DC braking (refer to p1232).
For p1346 = 0, the following applies:
The integral time of the I_max voltage controller is de-activated.

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).
p1349[0...n]

U/f mode resonance damping maximum frequency / Uf res_damp f_max

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: U/f open-loop control
Not for motor type: -
Min
0.00 [Hz]
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.
p1350[0...n]

U/f control soft start / U/f soft start

VECTOR_G Can be changed: U, T
Data type: Integer16
P-Group: U/f open-loop control
Not for motor type: -
Min
0
Description: Sets whether the voltage is continuously increased during the magnetizing phase (p1350 = 1, On) or whether it jumps
directly to the voltage boost (p1350 = 0, Off).
Value: 0:
1:
Dependency: The function is not effective for p1300 = 15.
Note: The settings for this parameter have the following advantages and disadvantages:
0 = off (jump directly to voltage boost)
Advantage: Flux is established quickly -> torque is quickly available
Disadvantage: The motor can move while it is being magnetized
1 = on (voltage is continually established)
Advantage: The motor is unlikely to rotate
Disadvantage: The flux is established slower -> torque is available later
