4.4.8 TenZoneDwStream
This input configures the regulator’s output based on the drive’s position in the web
path. If the tension zone controlled by the section is up stream (before) the section,
set this input low. If the tension zone controlled by the section is down stream (after)
the section, set this input high.
Usage – Set this input based on section position relationship to the master section
4.4.9 ReverseRotation
This input reverses the Rotation of the drive. It is used for Over/Under Wind
Operation. Setting this input high indicates an Under Wind operation. If the winder /
unwind is only operated in the under wind mode, configure the machine for positive
direction equals under wind and set this bit low
Usage – Set this input to change the polarity of the rotation based on machine
parameters.
4.4.10 TrimHoldHigh
This input holds the positive output of the PI Regulator.
Usage – Use this input to hold the PI regulator from increasing in value.
4.4.11 TrimHoldLow
This input holds the negative output of the PI Regulator.
Usage – Use this input to hold the PI regulator from decreasing in value.
4.4.12 TenRfStall
The tension reference typically is set to a lower value while the machine is at rest and
the tension regulator remains activated. This input activates the stall tension
reference. When activated, the tension reference is switched to the stall tension
reference.
Usage – Use this input to set the tension reference to a lower value while the
machine is at or near zero speed.
4.4.13 TrqFbJLoss
This parameter is set depending on the components of the torque feedback used in
the application program. If the torque feedback from the drive contains the inertia
and losses torque components, this value should be set to 1.
Usage – Use this input if the torque feedback (torque producing current) includes the
losses compensation.
4.4.14 TrqMemEnbl
The Torque Memory Enable feature is used when transferring rolls on a turret winder
stand. When torque memory is enabled, the tension control mode is change to
Torque Open Loop. There is a separate subroutine to handle Torque Memory.
Usage – Use this input if the Torque Memory Subroutine is present.
4.4.15 TrqFolwCtrl
The Torque Follower Controller is used when the drive is following a torque signal
from another drive. The tension control mode is Torque control but he reference is
entered as PU torque and not tension. This mode sometimes is referred to as load
sharing.
Usage – Use this input if the drive is following a torque reference signal from another
drive.
