11.4 Configuring the Frequency Input
ANLG
OUT
2
SELECT
(P.421)
Selects the signal
used to drive analog
output 2 (terminals
56 and 57 on the I/O
Expansion kit).
Parameter Range:
See table 11.1 for options.
Default Setting:
ZERO
Parameter Type:
Configurable
OIM Menu Path(s):
Input/Output - Analog I/O
When the analog output is at its maximum value, the selected signal is at is full
scale value.

FREQ
IN
(P.491)
The digital value of
the frequency input
(terminals 39, 40,
and 41 on the I/O
Expansion kit).
Parameter Range:
0 to 4095
Default Setting:
n/a
Parameter Type:
Output
OIM Menu Path(s):
Input/Output - Frequency I/O
FREQ
IN
is scaled between
FREQ
IN
ZERO
and
FREQ
IN
FULL
SCALE
.
FREQ
IN
is zero when the frequency at the input is less than or equal to
FREQ
IN
ZERO
. It is 4095 when the frequency equals
FREQ
IN
FULL
SCALE
.
FREQ
IN
FULL
SCALE
(P.424)
Specifies the
maximum input
frequency. This is the
frequency that
corresponds to full
scale value.
Parameter Range:
2.0 to 250.0 kHz
Default Setting:
250.0 kHz
Parameter Type:
Configurable
OIM Menu Path(s):
Input/Output - Frequency I/O
For example, if the frequency input will be used as the speed loop reference
(selected by
AUTO
REFERENCE
SELECT
(P.103)), this input frequency will correspond
to
TOP
SPEED
(P.011), because
TOP
SPEED
is the basis for speed loop scaling.
