Description of choices:
[2] Selection of digital reference: Selected to
select between 4 different preprogrammed
[3]
speed references, with the help of a binary
code according to this table:
Digital reference
1 (parameter 205)
2 (parameter 206)
3 (parameter 207)
4 (parameter 208)
Speed up/down: Selected for digital speed
control up/down (motor potentiometer).
The function is only active if Freeze refer-
ence/Freeze jogging reference has been
selected in parameters 400, 401 or 405,
and the equivalent terminal 16, 17 or 29 is
"on" (+24 V). As long as terminal 32 is "1"
(+24 V), the output frequency will increase
towards f (parameter 202).
MAX
For as long as terminal 33 is "1" (+24 V),
the output frequency will drop towards f
(parameter 201). Terminal 33 is most
significant.
No reference-

A pulse (logical "1" with duration between
20 ms and 500 ms) will cause a speed
change of 0.1 Hz to the output.
Logic "1" for more than 500 ms will cause
the output frequency to change according
to the set ramps (parameters 215 and
216).
Speed reference can be set even though
the unit has stopped (does not apply to
free-wheeling stop, quick stop or D.C.
brake on terminal 27). Speed reference is
remembered after mains cut-out if it has
been constant for at least 15 sec. (See
also parameter 014).
Setup select: If "multi setup" has been
selected in parameter 001, there is a
choice between setup 1, setup 2, setup 3,
or setup according to this table:
