YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
d2: Frequency Upper and Lower Limits
Use d2 parameters to configure the frequency reference limits.
Sets the maximum frequency reference as a
percentage of maximum output frequency
(E1-04). If the frequency reference is above this
value, actual drive speed will be limited to this
value. This parameter applies to all frequency
reference sources.
Sets the minimum frequency reference as a
percentage of maximum output frequency
(E1-04). If frequency reference is below this
value, actual drive speed will be set to this value.
This parameter applies to all frequency
reference sources.
Sets the minimum frequency reference, set as a
percentage of maximum output frequency
(E1-04). If frequency reference from analog
input(s) is below this value, actual drive speed
will be set to this value. This parameter applies
to all frequency reference sources.
d3: Jump Frequency
Use d3 parameters to configure the drive Jump Frequency settings.
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.
Although the drive will not operate the motor at
the frequencies it is programmed to skip, it will
pass through the designated Jump Frequencies
normally during acceleration and deceleration.
This parameter sets the width of the dead-band
around each selected prohibited frequency
reference point.
The bandwidth becomes the designated Jump
frequency, plus or minus d3-04.
