Adjustment of the dancer-Position controller
9.8.1
Setpoint
Provision
The act. value
Signal
of the dancer-Position controller is set via the
terminals 3 and 4.
The input
Signal
is displayed as percentage
under
code
CO51 with
Cl72 =
-O-.
In this
case
IOV
= 100%. The input
Signal
is resolved
with 12 bits
(iOV/4096
=
2.44mV)
plus sign.
For the input of the dancer-Position setpoint, the dancer must be
adjusted normally to the desired operating Position. The percentage
tan
be read
under
CO51,
this value must be
changed
into
Volts
(1
OV=l
00%) and then entered
under
Cl
81.
Example:
CO51 = -48%
Cl
81 = -48% *
1
OV/i
00%
=
-4.8V
The
differente
between
setpoint
and act. value value of the dancer
is entered into the PID controller as input value. When
changing
the
direction of rotation
_
calused
by
e-g.
a reversing command via the
terminals 21 and 22
-
the input
Signal
of the PID controller is also
inverted.
Caution!
DO not reverse the direction of transport (coupling in the dancer-
Position
control loop) by reversing the direction of rotation via the
digital inputs, terminals
21,22.
For returning the material,
inverl

input
Signal
