Avoidance Frequency Enable

Parameter Range: OFF
ON
Initial Setting: OFF
Type: Tuneable (at rest or during operation)
Refer to : P.003 Minimum Speed
H.010 to H.015 Avoidance Frequency Midpoint and Band 1, 2, and 3
Description: This parameter enables the avoidance
frequency bands selected in H.011, H.013,
and H.015.
Operating
particular frequency may cause vibrational
resonance within some machines. Three
independent
configured for avoidance frequency and
frequency band. to prevent motor vibration
by preventing the drive output frequency
from operating within the selected band(s).
The actual avoidance frequency selection is
limited by Minimum Speed (P.003) and
Maximum Speed (P.004). Normal accele-
ration and deceleration is not affected by this
function. The avoidance frequency function
is effective at any operation Control Source
selection (P.000).
H.010,H.012,H.014 Avoidance Frequency Midpoint No.1, 2, and 3
Parameter Range: 0.0 Hz - 200.0 Hz
Initial Setting: 0.0 Hz
Type: Tuneable (at rest or during operation)
Refer to : H.009 Avoidance Frequency Enable
H.011, H.013, H.015 Avoidance Frequency Band 1, 2, and 3
Description: This parameter specifies the midpoint of each avoidance frequency band selected
in H.011, H.013, and H.015. The adjusted values may be in any order. The
frequency will not be affected at normal acceleration / deceleration but will be
avoided at continuous output frequency.
H.011,H.013,H.015 Avoidance Frequency Band No.1, 2, and 3
Parameter Range: 2.0 Hz - 10.0 Hz
Initial Setting: 2.0 Hz
Type: Tuneable (at rest or during operation)
Refer to: H.009 Avoidance Frequency Enable
H.010, H.012, H.014 Avoidance Frequency Midpoints 1, 2, and 3
Description: This parameter specifies the avoidance frequency band that will be applied to each
avoidance frequency midpoint selected in H.011, H.012, and H.014.
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.
