How to program the Frequency Converter
Function:
Select the inverter switching frequency. Changing the switching fre-
quency can help to reduce acoustic noise from the motor.
NOTE: The output frequency value of the frequency converter must nev-
er exceed 1/10 of the switching frequency. When the motor is running,
adjust the switching frequency in par. 14-01
the motor is as noiseless as possible. See also par. 14-00
tern and the section Derating
Function:
Selects no over-modulation of the output voltage in order to avoid torque
ripple on the motor shaft.
The over-modulation function generates an extra voltage of up-to 8% of
U output voltage without over-modulation, which results in an extra
max
torque of 10-12% in the middle of the over-syncronous range (from 0%
at nominal speed rising to approximately 12% at double nominal speed).
Function:
Up to three different feedback signals can be used to provide the feed-
back signal for the frequency converter's PID Controller.
This parameter defines which input will be used as the source of the first
feedback signal.
Analog input X30/11 and Analog input X30/12 refer to inputs on the op-
tional General Purpose I/O board.
