8.2
Winding diameter calculation setting
Purpose
To perform setting for winding
diameter calculation
To calculate the winding diameter
from the actual line speed
To select the actual line speed
input method
To select the line speed command
setting unit
To calculate the winding diameter
from the material thickness
To set the line speed command or
actual line speed to start winding
diameter calculation
To set a limit to the minimum/
maximum value of the winding
diameter calculation result
To output the signal when the
predetermined winding diameter is
reached
To store the present winding
diameter/length value
