Frequency range (f
RANGE
)
(Freq range)
Set the maximum of the frequency convert-
er’s output frequency range.
201
Min. frequency (f
MIN
)
(Min frequency)
The output frequency corresponding to the
minimum reference input.
202
Max. frequency (f
MAX
)
(Max frequency)
Value:
f
MIN
- f
RANGE
The output frequency corresponding to the
maximum reference input.
203
JOG frequency
(JOG frequency)
A preset output frequency. The jog fre-
quency can be lower than the minimum
output frequency recorded in parameter
201, but is limited by the f
MAX
setting in
parameter 202. The JOG frequency can be
activated via the keyboard or terminal 29
(para. 405).

204
Digital reference type
(Dig. ref. type)
On selection of sum one of the digital refer-
ences (parameters 205-208) as a percent-
age of f
MAX
is added to the other references.
On selection of
relative one of the digital
references (parameters 205-208) is added
as a percentage of the other references.
On selection of
external on/off none of the
digital references is added.
It is possible to switch between the other
references and one of the digital referen-
ces (parameters 205-208) via terminal 29
(parameter 405).
NB: The sign determines only the running
direction when external to/from is selected.
Other references are the sum of the ana-
logue, pulse and bus references.
One of the digital references is selected via
terminals 32 and 33, (para. 406) cf. the
table below.
