5–20 Programming
This group contains the necessary parameters to activate and program advanced features
of the drive.
Feature Select
[Dwell Frequency]
This value sets the frequency that the drive will
immediately output (no Accel Ramp) upon a start
command. This parameter requires a programmed
[Dwell Time].
Parameter Number 43
Parameter Type Read and Write
Display Units / Drive Units 0.1 Hertz / Hertz x 10
Factory Default 0.0 Hz
Minimum Value 0.0 Hz
Maximum Value 7.0 Hz
[Dwell Time]
This value sets the time the drive will continue to
output [Dwell Frequency] before ramping to [Freq
Command].
Parameter Number 44
Parameter Type Read and Write
Display Units / Units 1 Second / Seconds
Factory Default 0 Sec
Minimum Value 0 Sec
Maximum Value 10 Sec

[Slip @ F.L.A.]
Sets the amount of automatic increase or decrease
to the drive output to compensate for motor slip.
When [Speed Control] is set to “Slip Comp”, a
percentage of this value proportional to output
current is added to the drive output frequency. When
[Speed Control] is set to “Droop”, a percentage of
this value proportional to output current is subtracted
from the drive output frequency.
Parameter Number 42
Parameter Type Read and Write
Display Units / Drive Units 0.1 Hertz / Hertz x 10
Factory Default 0.0 Hz
Minimum Value 0.0 Hz
Maximum Value 5.0 Hz
[Run On Power Up]
This parameter enables the function that allows the
drive to automatically restart on Power Up. This
parameter requires that a two wire control scheme
be installed at TB3 and that a valid start contact be
present. Refer to Input Mode Selection figure in
Chapter 2.
Parameter Number 14
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0
“Enabled” 1
ATTENTION: This parameter may only be used as outlined in
NFPA79, paragraph 6-14 (exceptions 1-3) for specialized
applications. Equipment damage and/or personal injury may
result if this parameter is used in an inappropriate application.
