Rockwell Automation 1336Z SPIDER - FRN 2.xxx-5.xxx - Manual (Page 89)

Programming 7–17
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
continuously 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
frequency, 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 TB5 & TB6 (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
issued by the MOP inputs will be saved to EEPROM (in
the event of power loss) and reused on power up. When
disabled, 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 Display Drive
“Disabled” 0
“Enabled” 1
[Freq Ref SqRoot]
This parameter activates the square root function for 0-
10V or 4-20 mA inputs when used as a frequency
reference. If the input signal varies with the square of
speed, the parameter should be set to “Enabled.”
Parameter Number 229
Parameter Type Read and Write
