p1338[0...n] U/f mode resonance damping gain / Uf Res_damp gain
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6300, 6310,
6853
Min:
0.00 Max:
100.00 Factory setting:
0.00
Description: Sets the gain for resonance damping for U/f control.
Dependency: See also: p1300, p1349
Note
The resonance damping function dampens active current oscillations that frequency occur under no-load conditions.
The resonance damping is active in a range from approximately 6 % of the rated motor frequency (p0310). The shutoff
frequency is determined by p1349.
For the open-loop control modes p1300 = 5 and 6 (textile sectors), the resonance damping is internally disabled in order
that the output frequency can be precisely set.
p1340[0...n] I_max frequency controller proportional gain / I_max_ctrl Kp
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6300
Min:
0.000 Max:
0.500 Factory setting:
0.000
Description: Sets the proportional gain of the I_max frequency controller.
The I_max controller reduces the drive converter output current if the maximum current (r0067) is exceeded.
In the U/f operating modes (p1300) for the I_max control, one controller is used that acts on the output frequency and
one controller that acts on the output voltage. The frequency controller reduces the current by decreasing the
converter output frequency. The frequency is reduced down to a minimum value (equaling twice rated slip). If the
overcurrent condition cannot be successfully resolved using this measure, then the drive converter output voltage is
reduced using the I_max voltage controller. Once the overcurrent condition has been resolved, the drive is accelerated
along the ramp set in p1120 (ramp-up time).
Dependency: In the U/f modes (p1300) for textile applications and for external voltage setpoints, only the I_max voltage controller
is used.
