Programming 6–17
Frequency Set
[Skip Freq 1]
[Skip Freq 2]
[Skip Freq 3]
These values, in conjunction with [Skip Freq Band], create
a range of frequencies at which the drive will not continu-
ously operate.
Parameter Number(s) 32-34
Parameter Type Read and Write
Display Units / Drive Units 1 Hertz / Hertz
Factory Default 400 Hz
Minimum Value 0 Hz
Maximum Value 400 Hz
[Skip Freq Band]
Determines the bandwidth around a skip frequency. The
actual bandwidth is 2 x [Skip Freq Band] –– one band
above and one band below the skip frequency.
Example:
[Skip Freq] = 20 Hz and [Skip Freq Band] = 4 Hz
Bandwidth = 8 Hz (16-24 Hz)
The output frequency will remain outside the total “band.”
When the actual command crosses the actual skip fre-
quency, the output will ramp through the entire band.
Parameter Number 35
Parameter Type Read and Write
Display Units / Drive Units 1 Hertz / Hertz
Factory Default 0 Hz
Minimum Value 0 Hz
Maximum Value 15 Hz
[MOP Increment]
This value sets the rate of increase or decrease to the [Freq
Command] for each input at TB3 (if programmed).
Parameter Number 22
Parameter Type Read and Write
Display Units / Drive Units 0.1 Hertz/Second / 255=(78% of [Maximum Freq])/Sec
Factory Default 1.1 Hz/Sec
Minimum Value 0 Hz/Sec
Maximum Value (78% of [Maximum Freq]) / Sec
[Save MOP Ref]
If this parameter is enabled, the frequency command is-
sued by the MOP inputs will be saved to EEPROM (in the
event of power loss) and reused on power up. When dis-
abled, no value is saved and the MOP reference is reset
to zero on power up.
Parameter Number 230
Parameter Type Read and Write
Factory Default “Disabled”
Units

“Disabled” 0
“Enabled” 1
[Freq Ref SqRoot]
This parameter activates the square root function for
0-10V/4-20 mA inputs or signals sent through Adapters 1-
6 when used as a frequency reference. If the input signal
varies with the square of speed, the parameter should be
set to “Enabled.”
