Roll diameter setting of torque mode tension control
)
Chart 4-21
:
Roll diameter setting of torque mode tension control
Set tention according to chart 4-20
Set F9.12, F9.13 max roll diameter and reel diameter
Set F9.18 ,F9.19 roll diameter reset mode and filter time
Set F9.21,F9.22 roll diameter calculate start frequency and delay time
Set F9.11 roll diameter calculate mode
F9.11=0, initial roll
diameter, no calculation
F9.11=4,5,6,7,8,
PUL giving
F9.11=1, linear speed
calculation
F9.11=2, thickness
calculation
F9.11=3, time calculation
Set F9.12 max
roll diameter
Set F9.25 linear
speed source
Set F9.39 material
thickness source
Set F9.44-F9.47 full roll
diameter and time
Set F9.26-F9.32 according
to the linear speed source
Set F9.38-F9.41 according to
the material thickness source
Get winding diameter and see C-12 the current diameterr
See C-10 tension setting, C-06 torque setting after diameter calculate
Use bad material test unwinding
Start run
Test ok
No
Yes
Test result
Check taper coefficience
Measure actual diameter same
as inverter calculate diameter
or not and adjust
