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.

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.

[MOP Increment]

This value sets the rate of increase or decrease to the [Freq
Command] for each input at TB5 & TB6 (if programmed).

[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.

[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.”
