Basic Parameter setting
Programming of the frequency controller enables the drive to be
adapted to your application. The possible settings are arranged in
Codes,
which are numbered in
ascending
Order
and
statt
with the
letter
“C”.
Esch
code
provides one Parameter which
tan
be
selected according to the application.
-
Parameters
tan
be absolute or relative values of a physical unit
(e.g.
50Hz
or 50% related
to
fdmax)
or
numerical
Codes
giving
certain
Status
information
(e.g.
-O-
=
controller inhibited,
-1-
controller enabled).
In
cases
where the Parameters represent values of physical units,
it is possible that the increment varies.
Example: The maximum field frequency
tan
be set in increments
of 0.1 Hz up to 1
OOHz,
and in increments of
1
Hz from
1
OOHz
upwards.
In some
Codes,
Parameters
tan
only be read but not changed.
In the factory setting, only those
Codes
are displayed which are
necessary
for the most common applications. For activation of the
extended
code
set see page 100.
2.1
Changing Parameters
Esch
code
has a factory set Parameter which
tan
be changed.
There are three different ways of selecting another Parameter,
depending on the
Code:
Direct
acceptance
The controller immediately accepts the new Parameter, i.e. while
you
Change
it using the UP or DOWN keys. This is possible even
when the drive is running.
Parameters which are immediately accepted are marked with ON-
LINE in the following programming tables.
Example:
Under
CO50,
the controller
Shows
the momentary field frequency in
Hz. You want to set a maximum field frequency (CO1 1) of 60Hz.
