Fn_37: Maximum Frequency 0.01 Hz = 50 to 400 Hz
Fn_38: Maximum Voltage Ratio 0.1 % = 0 to 100 %
Fn_39: Middle Frequency 0.01 Hz = 0.11 to 400 Hz
Fn_40: Middle Voltage 0.1 % = 0 to 100 %
Fn_41: Minimum Voltage Ratio 0.1 % = 0 to 100 %
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.
Fn_43: Carrier frequency = 1 –12 kHz
Fn_43 Carrier freq. Fn_43 Carrier freq. Fn_43 Carrier freq. Fn_43 Carrier freq.
0 1 kHz 4 2.4 kHz 8 4.8 kHz 12 8 kHz
1 1.2 kHz 5 3 kHz 9 5 kHz 13 9 kHz
2 1.8 kHz 6 3.6 kHz 10 6 kHz 14 10 kHz
3 2 kHz 7 4 kHz 11 7.2 kHz 15 12 kHz
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.
