AC90 TENSION CONTROL FREQUENCY INVERTER MANUAL
Open-loop /closed loop VC control（Roll diameter setting of torque mode tension control）
●
F9.11=0, initial roll
diameter, no calculation
Measure actual diameter same
as inverter calculate diameter
or not and adjust
Check taper coefficience
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=4,5,6,7,8,
F9.11=1, linear speed
PUL giving
calculation
Set F9.12 max
roll diameter
Set F9.26-F9.32 according
to the linear speed 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
No
