While Initial diameter resource selection [F9.14] is set as "0(Terminal select)", it can be select "Initial diameter setting
terminal" to define any terminals. Details see [F2.00-F2.07] ; 3 groups of Initial diameter can be supplied by terminal
switch. The relationship table is as below.
Initial diameter set 1
Note: while all terminals are OFF state, Initial diameter is reel diamerter [F9.13] setting. If need modify by RS485,
set [F9.14] as "0" and not define terminal. Modify Initial diameter in [F9.13] address of upper machine.
F9.18 Diameter reset selection
0: Manual reset Need define one terminal as "diameter reset terminal". While diameter reset terminal is valid, the
roll diameter of the inverter reset to initial diameter.
1: Auto reset Inverter resets the roll diameter to initial value automaticly after stop.
F9.19 Diameter filter time
It defines the filter time for roll diameter to clear outside disturbance to the roll diameter. The longer the time is, the
stronger the anti-disturb ability is. Roll diameter change respond speed will be weaker. The shorter the time is, the
weaker the anti-disturb ability is. Roll diameter change respond speed will be quicker.
Under tension control, if torque wave is obivious, diameter filter time can be increased properly to prevent the torque
wave for diameter calculate not stable.
F9.20 Current roll diameter
This parameter can monitor the current roll diameter in real time. It can be compared to the actual diameter while
debugging. The current roll diameter can be adjusted by this parameter.
Roll diameter calculate
F9.21
end frequency
Set the lowest frequency where begin to calculate the roll diameter. While the output frequency is lower this value,
frequency inverter stop roll diameter calculate. Right setting can prevent big error of roll diameter calculate at low
speed.
