Sets the frequency reference upper limit as a percentage of the maximum output
frequency.
Sets the frequency reference lower limit as a percentage of the maximum output
frequency.
Sets the lower limit for frequency references from analog inputs as a percentage
of the maximum output frequency.
Eliminates problems with resonant vibration of the motor/machine by avoiding
continuous operation in predefined frequency ranges. The drive accelerates and
decelerates the motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
Sets the dead-band width around each selected prohibited frequency reference
point.
0: Disabled. Drive starts from zero when the power is switched on.
1: Enabled. At power up, the drive starts the motor at the Hold frequency that
was saved.
Sets the bias added to the frequency reference when the Up 2 and Down 2 digital
inputs are enabled (H1- = 75, 76).
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
0: Bias value is held if no input Up 2 or Down 2 is active.
1: When the Up 2 reference and Down 2 reference are both on or both off, the
applied bias becomes 0. The specified accel/decel times are used for
acceleration or deceleration.
The Up/Down 2 bias value is saved in d4-06 when the frequency reference is not
input by the digital operator. Set as a percentage of the maximum output
frequency.
Limits how much the frequency reference is allowed to change while an input
terminal set for Up 2 or Down 2 is enabled. If the frequency reference changes
for more than the set value, then the bias value is held and the drive accelerates
or decelerates to the frequency reference. Set as a percentage of the maximum
output frequency.
Sets the upper limit for the bias and the value that can be saved in d4-06. Set as a
percentage of the maximum output frequency.
Sets the lower limit for the bias and the value that can be saved in d4-06. Set as a
percentage of the maximum output frequency.
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
