In order to build Custom V/Hz Patterns, (Fn_05) must be set at 18.
Fn_42: Starting Frequency = 0.1 - 10 Hz
The T-verter can start at 5 Hz and still have an operational control range of 0.1 ~ 60 Hz. To
accomplish this (Fn_07) will need to be set at 0 Hz, and (Fn_42) at 5 Hz.

Note:
An IGBT type T-verter can provide a lower audible motor noise using a higher carrier frequency.
However, a drive with to high of a carrier frequency may lead to interference in other electronic
equipment. It’s recommended that a carrier frequency of not more than 10 or 12 kHz be used for
protection of the motor and surrounding equipment that may be sensitive to high carriers.
