OutputFrequency

Fout x (11-32) x K
K is a coefficient; the value of K is based on the following based on the maximum carrier frequency:
K=1: when 11-30 < 5 KHz
K=2: when 10 KHz > 11-
30 ≥ 5 KHz
K=3: when 11-
30 ≥ 10KHz
Notes:
- In V/F and V/F + PG control mode if the speed and torque are constant, the variable carrier frequency mode
(11-01=0) can be selected to reduce the carrier frequency based on output frequency.
- If the carrier frequency proportional gain (11-32) > 6 and 11-30 < 11-31, error message "SE01" out of range will
appear on the keypad.
- If the minimum limit (11-31) is set higher than the maximum limit (11-30), the minimum limit will be ignored and
the carrier frequency will be set at the highest limit (11-30).
- In fixed carrier frequency mode (11-01 = 2-16) parameters 11-30, 11-31 and 11-32 are not used.
- In SLV and SV control mode, the maximum limit of the carrier frequency is fixed at 11-30.
