WINDING DIAMETER COMPENSATION FUNCTION

8.2.9
Target winding diameter achieved
When the winding diameter calculated in the inverter is equal to or more than the parameter setting, the Target winding
diameter achieved (Y233) signal is output.
Target winding diameter achieved (Pr.648, Y233 signal)
• When the result of winding diameter calculation in the inverter is equal to or more than the
Pr.648 Target winding
diameter
setting, the Target winding diameter achieved (Y233) signal can be output.
• The Y233 output condition depends on whether the operation is winding or unwinding.
8.2.10
Winding diameter calculation at a start
When the dancer roll is moved from the upper/lower limit position to the target position at start, the present winding diameter
is calculated.
