Description: The linear characteristic for the U/f control is defined by 0 Hz / p1319 and p1326 / p1327.
This parameter specifies the frequency of the fourth point along the characteristic.
Dependency: The U/f control is activated via p1317 = 1.
Refer to: p1317, p1319, p1327
Note: Linear interpolation is carried out between the points 0 Hz/p1319 and p1326/p1327.
Description: The linear characteristic for the U/f control is defined by 0 Hz / p1319 and p1326 / p1327.
This parameter specifies the voltage of the fourth point along the characteristic.
Dependency: The U/f control is activated via p1317 = 1.
Refer to: p1317, p1319, p1326
Note: Linear interpolation is carried out between the points 0 Hz/p1319 and p1326/p1327.
Description: Sets the gain for resonance damping for U/f control.
In U/f mode, the resonance damping function dampens oscillations that are frequently experienced by induction
motors in certain speed ranges and by synchronous motors above even low speeds.
Dependency: Refer to: p1317, p1339, p1349
Note: Resonance damping is active in the following ranges:
- Active: 3.1 Hz ... p1349
- Build-up (linear): 3.1 ... 4.77 Hz
- Reduction (linear): 0.95 * p1349 ... p1349
Where the value = 1 and at the oscillation amplitude of the rated current, the rated slip frequency is switched in for
induction motors, while a frequency of 10 Hz is switched in for synchronous motors.
Description: Sets the filter time constant for resonance damping for U/f control.
