P2-14
n-decMulti1
Frequency / speed, at which the deceleration ramp changes
from t-dec2 to t-dec1.
This can be set to any value between 0 and “f-max” (P1-01).
Nominal motor speed (P1-10) = 0: Displayed in Hz
Nominal motor speed (P1-10) > 0: Displayed in rpm
Frequency / Speed > P2-14 = t-dec2
Frequency / Speed < P2-14 = t-dec1

P2-15
f-Skip1
Center point of the frequency band defined by f-Skip-Band1
in which the drive doesn't work in steady-state.

P1-01
0
P2-16
f-SkipBand1
Skip frequency band width
Defines the frequency range around f-Skip1 in which the
drive doesn't work in steady-state to avoid mechanical reso-
nances in the application.
Lower limit = P2-15 - P2-16/2
Upper limit = P2-15 + P2-16/2
The definition applies for both senses of rotation.

drive doesn't work in steady-state to avoid mechanical reso-
nances in the application.

P2-20
f-MidV/f
Frequency to shape V/f curve
When operating in V/f mode (P6-01 = 6) this parameter is
used in conjunction with P2-21 and sets a frequency point at
which the voltage set in P2-21 is applied to the motor.
Care must be taken to avoid overheating and damaging the
motor when using this function.

P2-22
Switching frequency
Power stage switching frequency
Higher frequency reduces the audible ’ringing’ noise from the
motor, and improves the output current waveform,
Disadvantage: Higher loss in the device.
0: 4 kHz
1: 8 kHz
2: 12 kHz
3: 16 kHz
4: 24 kHz
5: 32 kHz
Attention:
In case a sine wave filter is used, the switching frequency
has to be in the range which is permissible for the filter. In
this case P2-22 has to be set to twice the switching
frequency mentioned on the filter.
