Description
d3-01 to d3-04 allow programming of three prohibited
frequency reference points for eliminating problems with
resonant vibration of the motor / machine. This feature does
not eliminate the selected frequency values, but accelerates and
decelerates the motor through the prohibited bandwidth.
The parameters must be according to the rule
d3-01 ≥ d3-02 ≥ d3-03.
This parameter sets the dead-band width around each selected
prohibited frequency reference point. The bandwidth becomes
the designated Jump frequency, plus or minus d3-04.
d4: Frequency Reference Hold
Use d4 parameters to configure the drive frequency reference hold function.
Determines if the frequency reference or frequency reference
bias is saved when the Run command is removed or the power
goes off.
0: Disabled
1: Enabled
This parameter is effective when the multi-function inputs
"Accel/Decel Ramp Hold", "Up/Down" or "Up/Down 2"
commands are selected (H1-oo = A or 10/11 or 75/76).
Sets the bias added to the frequency reference when the Up/
Down 2 digital inputs are set.
When set to 0.00 Hz, the bias value is increased or decreased
according to d4-04.
When greater than 0.0 Hz, the bias value d4-03 is added or
subtracted to/from the frequency reference. The acceleration
or deceleration rate is ultimately determined by d4-04.
Selects how the bias or frequency reference is increased when
using the Up/Down 2 function.
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.
Currently selected accel / decel. times are used. Enabled only
when d4-03 = 0.
The Up/Down 2 bias value is saved in d4-06 when the
frequency reference is not input by the digital operator. The
function depends on the setting of d4-01.
It is limited by d4-08 and d4-09.
When an Up 2 or Down 2 input is active and the frequency
reference value from analog or pulse input changes for more
than the level set in d4-07, the bias value is hold and the
frequency reference is changed to the new value.
After the speed reaches the frequency reference the bias hold
is released.
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
E1-04.
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
E1-04.
Selects which value is used as frequency reference lower limit
if the Up/Down function is used.
0: The lower limit is determined by d2-02 or analog input
(H3-02/10 = 0). The higher of both values becomes the
reference limit.
1: The lower limit is determined by d2-02.
d7: Offset Frequency
Use d7 parameters to set the offset frequency.
Added to the frequency reference when the digital input
"Frequency Offset 1" (H1-oo = 44) is switched on.
Added to the frequency reference when the digital input
"Frequency Offset 2" (H1-oo = 45) is switched on.
Added to the frequency reference when the digital input
"Frequency Offset 3" (H1-oo = 46) is switched on.
