4-64 GV3000/SE 230 VAC Drive, Software Reference Version 6.04
H.011, H.013, H.015 Avoidance Frequency Band 1, 2, and 3
This parameter
specifies the
avoidance frequency
band that will be
applied to each
avoidance frequency
midpoint selected in
H.010, 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.
Parameter Range: 0.2 to 10 Hz
Default Setting: 2.0
Parameter Type: Tunable
Refer also to parameters: H.009 Avoidance Frequency Enable
H.010, H.012, H.014 Avoidance Frequency
Midpoints 1, 2, and 3
H.016 Sync Direction
When starting into a
rotating load is
required, this
parameter selects
the direction in which
the drive will search
in order to
synchronize to motor
speed. Parameter Range: OFF = Disable synchronization
F = Search starts in motor forward direction
r = Search starts in motor reverse direction
Fr = Search starts in motor forward then reverse
direction
rF = Search starts in motor reverse then forward
direction
Default Setting: OFF
Parameter Type: Configurable
Refer also to parameters: N/A
Note that when Forward/Reverse Configuration (P.027) is set to 1, setting this
parameter to r, Fr, or rF may cause the motor to operate in the reverse direction.
ATTENTION: When starting with search enabled, there will be a
several second delay, and motor may drift in the forward and reverse
direction, before the motor begins operating in the desired direction
even if reverse has been disabled in P.027. Stay clear of rotating
machinery. Failure to observe this precaution could result in bodily
injury.
