No. Name
d3-01 Jump d3-01 to d3-04 allow programming of three
Frequency 1 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
d3-02 Jump
motor through the prohibited bandwidth.
Frequency 2
The parameters must be according to the rule
d3-01 ≥ d3-02 .
This parameter sets the dead-band width around each
Jump
selected prohibited frequency reference point. The
d3-04 Frequency
bandwidth becomes the designated Jump frequency,
Width
plus or minus d3-04.
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
Frequency removed or the power goes off.
Reference 0: Disabled
d4-01
Hold Function 1: Enabled
Selection This parameter is effective when the multi-function
inputs "Accel/Decel Ramp Hold" or "Up/Down"
commands are selected (H1-oo = A or 10/11).
<1> Parameter can be changed during run.
<2> Range upper limit is dependent on parameters E1-04, Maximum Output Frequency, and d2-01, Frequency
Reference Upper Limit.
