Target Winding Diameter Achieved - Mitsubishi Electric A800 Plus Series Function Manual

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.
Winding/unwinding
Winding Output when the winding diameter reaches or exceeds the Pr.648 setting.
Unwinding Output when the winding diameter reaches or falls below the Pr.648 setting.
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.

WINDING DIAMETER COMPENSATION FUNCTION
Winding diameter calculation setting
Description
Set the winding diameter to output the Target winding
diameter achieved (Y233) signal.
Description
Set the target position for the dancer roll.
The initial winding diameter calculation is performed
when the dancer roll position is equal to or lower than
the setting of this parameter.
Set the deadband on the lower limit position.
Set the deadband on the target position.
The deadband on the target position is as set in
Pr.1253.
Set the accumulated amount.
The initial winding diameter calculation is invalid. (When
the dancer roll position is equal to or lower than the
Pr.1252 setting, the dancer roll is lifted.)
Initial winding diameter calculation invalid
Set the speed control proportional gain during initial
winding diameter calculation at start.
Set the speed control integral time during initial winding
diameter calculation at start.
Set the integral action limit value during initial winding
diameter calculation at start.
Set the PID manipulated amount limit value during
initial winding diameter calculation at start.
