Line speed at winding diameter calculated value
activation
Set the line speed command value or actual line speed to start winding diameter calculation. When the line speed command
value or actual line speed is lower than the speed to start winding diameter calculation, winding diameter calculation is not
performed and the last winding diameter value is kept.

The increment varies depending on the
Pr.358
setting.
Line speed at winding diameter calculated value activation during
dancer feedback / tension sensor feedback speed control
• During dancer feedback speed control or tension sensor feedback speed control, when the line speed command value is
equal to or higher than
Pr.1246
, winding diameter calculation is performed, and the winding diameter calculation result is
updated. When the line speed command value is lower than the
Pr.1246
setting, winding diameter calculation is not
performed and the last winding diameter value is kept.
• It is possible to prevent the change in the winding diameter, which may be caused by calculation errors at low-speed
operation.
