Winding diameter calculation setting

WINDING DIAMETER COMPENSATION FUNCTION
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).
8.2.8
Winding diameter compensation speed filter
Set the time constant of the primary delay filter relative to the winding diameter compensation speed.
• 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.
