Actual signals and parameters
Description
Tension control and PI regulator setup.
Note: This group is hidden unless a Tension macro is selected.
This parameter sets the immediate reaction step of the PI regulator.
63.01 P-GAIN 1 MIN sets the gain at
the gain is linear between 63.01 P-GAIN 1 MIN and
MAX. Typically, 63.02 P-GAIN 1 MAX is set larger to compensate for
the increased inertia of larger roll diameters.
The default values give a good starting point for the gain and they
should not be modified until the correct diameter is on the machine
and the machine is running. For example, do not adjust
1 MAX when the roll is around core. Likewise, do not adjust 63.01 P-
GAIN 1 MIN when the roll is built up. Note that too large of a gain
could lead to instability.
Setting range.
See 63.01
The default value gives a good starting point for the integration time of
the PI regulator. A lower integration time results in a more responsive
system; however, too low of an integration time can lead to instability.
Setting range.
Selects the activation signal source for forcing the integration time of
the tension PI regulator to zero. The PI controller will just become a P
controller
Function not selected.
Digital input DI2 = 1 forces the integration time to zero.
