5–19 Programming
[Skip Freq 1-3]
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]
This parameter determines the band width around a
[Skip Frequency]. The actual band width is
2 x [Skip Freq Band] –– 1/2 the band above and 1/2
the band below the skip frequency.
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

[Pulse/Enc Scale]
This parameter contains the scaling factor for both
pulse train inputs (TB2-7, 8) and encoder feedback
speed regulation (TB3 terminals 31-36).

Pulse Train Example:
4 Pole Motor, 60 Hz = Max. Speed.
The 1336–MOD–N1 option outputs 64 Hz/Hz.
At full analog reference, the pulse output will
be 60 Hz x 64 Hz/Hz = 3840 pulses/sec.

[Speed Filter]
A digital filter that sets the time constant for a single
pole speed command filter. This filter is located after
the active speed source is selected and before skip
speeds are checked.
Parameter Number 175
Parameter Type Read and Write
Display Units / Drive Units NA / NA
Factory Default 10
Minimum Value 1
Maximum Value 100
[Analog Filter]
An analog filter that sets the time command for the
single pole analog speed input filter. The pot,
isolated mA, 4-20 mA and 0-10 volt inputs are
filtered.
Parameter Number 176
