The adjusted values may be in any order. The frequency will not be affected at normal
acceleration or deceleration but will be avoided at continuous output frequency.
.
The avoided frequency range is:
(Avoidance freq. midpoint ‘n’ - freq. band ‘n’/2) < range < (avoidance freq. midpoint ‘n’ + freq. band ‘n’/2)
where n = 1, 2, or 3.
H.010, H.012, H.014 Avoidance Frequency Midpoint 1, 2, and 3
This parameter
specifies the midpoint
of each avoidance
frequency band
selected in H.011,
H.013, and H.015. Parameter Range: 0.0 to 200.0 Hz
Default Setting: 0.0
Parameter Type: Tunable
