How can the switching frequency for the ATV58 be changed?

Before the Switching Frequency setting can be adjusted it is necessary to verify that the drive is not running and in the programming mode.
The switch on back of the keypad must be in the total unlock position.
First go to the SFT(Switching Frequency Type) parameter in menu 3 - Drive Menu and adjust this to the desired range of switching frequency.
Then adjust SFr (Switching Frequency) to the desired value.
Make sure that derating of drive controller rating is considered when adjusting the switching frequency level.
