Standard Mode Selection
This parameter selects 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 Frequency Mode 1 ( F004) and Frequency Priority Selection ( F200) for
additional information on this setting.
Settings:
1 — VI/II
2 — RR
3 — RX
4 — RX2
5 — CN8 Option
6 — Binary/BCD (Option)
7 — Common Serial (TTL)
8 — RS232/RS485
9 — Communication Option Board
10 — UP/DOWN Frequency
11 — Pulse Input (Option)
Direct Access Number — F207

Standard Mode Selection
This parameter sets the threshold frequency that will be used to determine if
Frequency Source 1 or 2 will control the output of the ASD when Frequency
Source 1 Priority or Frequency Source 2 Priority is selected at F200 .
See F200 for additional information on this setting.
Direct Access Number — F208
Parameter Type — Numerical
Factory Default — 1.0
Changeable During Run — Yes
Minimum — 0.1

Units — Hz
Analog Input Filter

Analog Filter
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 — Small
2 — Medium
3 — Large
The analog input signal is sampled and converted to a digital signal. With no
filtering applied, the digital value from the conversion is scaled for use by the
microprocessor of the ASD.
If the filtering selection is Small , the ASD averages the last 5 sampled (digital)
values. The rolling average is updated (every 4 µS) and scaled for use by the
microprocessor.
If the filtering selection is Medium , the ASD averages the last 20 sampled
(digital) values. The rolling average is updated (every 4 µS) and scaled for use
by the microprocessor.
If the filtering selection is Large , the ASD averages the last 50 sampled
(digital) values. The rolling average is updated (every 4 µS) and scaled for use
by the microprocessor.
False responses to electrical noise are eliminated with no loss in bandwidth
because the value used by the drive is the average value of several samples.
