Winding diameter calculation setting
Stored winding length (Pr.1262, Pr.1263, Pr.1298, Pr.1299)
• While winding diameter calculation is valid, the winding length can be calculated from the integration of the actual line
speed value.
• For winding length calculation, the actual line speed is used whichever direction the line goes. When the material is
unwound after winding operation, the winding length is not subtracted but added. (When switching between winding and
unwinding is performed using the two-way operation function, the winding length is subtracted. (Refer to
• The winding length is calculated in the inverter in 0.1 mm increments. When the value exceeds 9999999999.9 mm, the
value is reset to 0 mm.
• Use Pr.1299 Stored winding length increment to change the increment of the stored winding length.
Pr.1299 setting Increment
0 (initial value) 1 m
1 1 cm
2 1 mm
The stored winding length is not changed immediately after changing the Pr.1299 setting. After changing the Pr.1299
setting, the stored wiring length is changed at the update timing set in Pr.645. (Refer to
• Read Pr.1263 Stored winding length (lower 4 digits) and Pr.1298 Stored winding length (upper 4 digits) to check the
stored winding length. The increment is determined by the setting of Pr.1262 Winding length increment.
Pr.1262 setting Increment
0 1 km
1 100 m
2 10 m
3 (initial value) 1 m
4 1 cm
5 1 mm
• The stored winding length can be changed by overwriting the setting value in Pr.1263 and Pr.1298 with a desired value.
The increment of values to be set in Pr.1263 and Pr.1298 can be set in Pr.1262.
• The setting values and readouts of Pr.1263 and Pr.1298 differ according to the settings of Pr.1299 Stored winding length
increment and Pr.1262 Winding length increment. For example, when "0" (1 m increment) is set in Pr.1299 and "0" (1
km increment) is set in Pr.1262, a value between "0" and "9999" can be set in Pr.1263, but a value other than "0" cannot be
set in Pr.1298. In this case, when "3" (1 m increment) is set in Pr.1262 after "9999" is set in Pr.1263, the readout of Pr.1263
will be "9000", and the readout of Pr.1298 will be "999". When "5" (1 mm increment) is set in Pr.1262, readout of Pr.1263
will be "0" and readout of Pr.1298 will be "9900".
NOTE
• Set Pr.1299 Stored winding length increment before setting a value in Pr.1263 or Pr.1298.
• When a value is set in either Pr.1263 or Pr.1298, "0" is automatically set in the other parameter only for the first time after the
setting of Pr.1299 Stored winding length increment is changed.
Stored winding diameter/length clear (X109 signal, X117 signal)
• Input the Stored winding diameter clear (X109) signal or Winding length clear (X117) signal to clear the stored winding
diameter/length.
• To use the X109 or X117 signal, set Pr.178 to Pr.189 (input terminal function selection) to assign the function to an input
terminal.

The minimum/maximum winding diameter is as selected by the X107/X108 signal. (Refer to
