WINDING DIAMETER COMPENSATION FUNCTION

Winding diameter calculation using material
thickness (thickness method)
The material thickness is added up for winding diameter calculation.
First to fourth material thickness can be selected by the signal input.
Selection of the thickness method (Pr.1231)
• When a value other than "9999" is set in
Pr.1231
, the winding diameter is calculated not from line speed but from the
addition of material thickness and number of roll rotations. (Thickness method)
• When selecting the thickness method, use an option, the FR-A8AP, FR-A8AL, or FR-A8TP, to input the encoder pulse (A/B
phase).
NOTE
• When
Pr.1231
= "9999", the winding diameter is calculated from the actual line speed. (Refer to
.)
• In the thickness method, the stored values of the initial winding diameter, material thickness, and number of roll rotations are
used for calculation. Set correct values for the initial winding diameter and the material thickness. If the setting of the initial
winding diameter is incorrect, or the actual material thickness and the material thickness setting (parameter setting) are
inconsistent, calculation errors are more likely to occur. If calculation errors occur, select the actual line speed method.
Material thickness selection (Pr.1232 to Pr.1234, X107 signal, X108
signal)
• Turn ON/OFF the Minimum/maximum winding diameter selection (X107 and X108) signals to select the material thickness
set in
Pr.1232 to Pr.1234
.
• For the X107 and X108 signals, assign the function by setting "107 (X107)" or "108 (X108)" in any of
Pr.178 to Pr.189
(input terminal function selection)
.
NOTE
• By turning ON/OFF the X107 and X108 signals, the maximum and minimum winding diameters are also selected. (For the
details, refer to
• 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).
