List of parameters
p1326[0...n] U/f control characteristic frequency / Uf char f4
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
0.00 [Hz]
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.
p1327[0...n] U/f control characteristic voltage / Uf char U4
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
0.0 [Vrms]
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.
p1338[0...n] U/f mode resonance damping gain / Uf Res_damp gain
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
0.00
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.
p1339[0...n] U/f mode resonance damping filter time constant / Uf Res_damp T
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
1.00 [ms]
Description: Sets the filter time constant for resonance damping for U/f control.
