detection
-.
The
diameter
compensator
tan
also be used for
indirect
diameter
detection where there is no
diameter
detection System. The
modulation of the dancer-Position controller enables a slow control
of the
diameter
compensator output, until the dancer-Position
controller returns to a modulation window (Cl 94) to be set. The
acceleration and deceleration times C
195/C196
must
be set in
seconds so that an instability in the control
caused
by the dancer
modulation is avoided. The acceleration and deceleration times
should
be set so that a
diameter
increase
tan
still be compensated.

Input of correction value
(only for asynchronous machines)
The correction value for the field frequency
tan
be set
during
acc’eleration
(see
Signal
flow
Chart
page 120). This value
tan
only
be entered as a bit value (+ 16383 to
-
16383) via the serial
interface
under
code
Cl 93 . lt
tan
be saved via CO03. The
resolution and the increment of the correction value is 0.03 Hz
-
as
the entered value 16383 equals 480 Hz.
Recommendation:
The entered correction value should not exceed the rated
Slip
frequency.
Caution!
The
entered value is immediately added to the calculated values
without
being processed by the ramp
function
generator. That
means that high correction
values
may lead to high torques and the
current
limiting
function
lmax
tan
be activated (see
Signal
flow
Chart
-
10).
