Winding diameter calculation setting
NOTE
• By turning ON/OFF the X107/X108 signal, the material thickness is also selected. (For the details, refer to
• If the minimum winding diameter setting is equal to or larger than the maximum winding diameter setting, the winding
diameter is fixed at the maximum diameter (minimum diameter) and therefore, the winding diameter does not change from
the maximum diameter (minimum diameter).
• When the maximum/minimum diameter is selected using the X107 and X108 signals, or the setting in Pr.1235 to Pr.1242 is
changed, the present winding diameter may be limited and change depending on the maximum/minimum winding diameter
setting. When the maximum/minimum winding diameter setting is newly selected or changed, check that the present winding
diameter is correct. If the value changes to an unintended value, correct the present diameter by performing one of the
following actions.
- Use Pr.646 Stored winding diameter to set the present diameter.
- Perform initial winding diameter calculation.
- Turn OFF the X114 signal (restore the initial winding diameter).

• Use Pr.1251 to set the time constant of the primary delay filter. When Pr.1251 = "0", the filter is not set.
• Use Pr.1250 to set a waiting time before applying the primary delay filter after the initial winding diameter calculation is
completed. When the initial winding diameter calculation is not performed, set the waiting time after a start.
