Frequency Mode 2
Program

Frequency Settings
This parameter is used to set the source of the frequency command signal to be
used as Frequency Mode 2 in the event that Frequency Mode 1 is disabled or if
Frequency Mode 2 is set up as the primary control parameter.
See F004 and F200 for additional information on this setting.

Freq Mode 1/Freq Mode 2 Switching Frequency
Program

Frequency Settings
This parameter establishes a threshold frequency that will be used as a reference
when determining when to switch the output frequency control source from the
Frequency Mode 1 setting to the Frequency Mode 2 setting.
See F200 for additional information on this setting.

Minimum — 0.10
Maximum — Max. Freq. ( F011 )
Units — Hz
Analog Input Filter
No Path — Direct Access Only
Analog filtering is applied after the analog reference signal is converted to a
digital signal. The type of filtering used is Rolling Average over time.
Settings:
0 — None (1 ms)
1 — Small (8 ms)
2 — Medium (16 ms)
3 — Large (32 ms)
4 — Huge (64 ms)
The analog input signal is sampled and converted to a digital signal. With no
filtering applied, the resulting digital value is scaled for use by the microprocessor
of the ASD.
If the filtering selection Small is selected, the ASD averages the last 8 ms of
sampled signal and converted (digital) values. The rolling average is updated
(every 4 µS) and scaled for use by the microprocessor.
This holds true for the Medium, Large, and Huge selections providing a larger
sample to produce the average for use by the microprocessor.
False responses to electrical noise are eliminated with no loss in bandwidth
because the value used by the ASD is the average value of several samples.
