Actual signals and parameters
Description
The factor Speed Share (Speed Multiplier) is used to scale the line
speed reference input to the rpm reference of the drive.
1. If Group 61 is being utilized, ensure that
SEL is set to "NOT SEL".
2. Put the drive in speed mode only, disable the tension and dancer
command (depending on selected operating mode).
TENSION CTL ENABLE to "NOT SEL" or
ENABLE to "NOT SEL." This sets the trim amount to zero so the
section will follow the line speed reference.
3. Ensure ALL SAFETY conditions are met to safely operate the
production line (machinery).
4. a.) WINDER:
The minimum core diameter should be placed in the winder.
Perform a Diameter Reset (see
that 03.13 ROLL DIAMETER indicates minimum core diameter.
The diameter of the section must be reset to this minimum core
value (65.01 MIN CORE DIAMETER).
b.) UNWIND:
Set 65.04 DIAMETER RESET 2 to the minimum core diameter and
65.03 DIAMETER RESET to DI3, 4. Set digital input DI4 high. This
will reset the Unwind to the value at 65.04. Verify that
DIAMETER indicates minimum core diameter.
Note: When complete, 65.04
DIAMETER RESET should be reset to their initial values or values
suitable for the application.
5. Without web in the machine, place the line in run and slowly
increase the line speed to approximately 50%.
6. Check the surface speed of sections with a tachometer (hand-
tach). Then without changing speeds, check the surface speed of
the winder core shaft.
7. Adjust 11.05 EXT1 REF MAXIMUM to match the core surface
speed to the line speed.
Note: 20.02 MAXIMUM SPEED must be greater than 11.05 EXT1
REF MAXIMUM or the speed of the section will be limited to
MAXIMUM SPEED.
Note: For both Winders and Unwinds, it is recommended to check the
speed matching of the section at 75% and 100% of machine speed.
This is always done with the Winder/Unwind at minimum core
diameter with the minimum core size in the machine.
Note: Speed Matching is required for all types of Winders and
Unwinds, including Single Position and Automatic Roll Change
machines.
