Winding diameter compensation
function
(3) Minimum winding diameter/maximum diameter and material thickness selection by external
terminal input (X53 signal, X54 signal)
By switching ON/OFF X53 signal and X54 signal, minimum/maximum winding diameter can be selected.
For the X53/X54 signal, set "53(X53)/54(X54)" in any of
Pr. 178 to Pr. 189 (input terminal function selection)
to assign the
function.
When X53/X54 are not assigned, maximum diameter is
Pr. 720
, and minimum diameter is
Pr. 721
.
Material thickness 1 to 4 can be selected with X53/X54 signals when the winding diameter calculation method based on
the material thickness is selected.

Rotation speed at winding diameter calculated value
activation
, winding diameter calculation is performed, and result of winding diameter calculation is updated.
When rotation speed does not reach
Pr. 797
Rotation speed at winding diameter calculated value activation
, winding diameter
calculation is not performed and last winding diameter value is kept.
Change of winding diameter, which is caused by calculation error at low-speed operation, can be reduced.
Winding diameter calculation is performed when main rotation speed reaches or becomes faster than
Pr. 797
.
Result obtained from winding diameter calculation is kept when main rotation speed does not reach
Pr. 797
.
