Winding diameter calculation setting
178
WINDING DIAMETER COMPENSATION FUNCTION
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.
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
.
• 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.
• When the winding diameter is cleared by the X109 signal, the value after clear is as follows.
∗1
Use
Pr.1230 Winding/unwinding selection
for the selection.
∗2
The minimum/maximum winding diameter is as selected by the X107/X108 signal. (Refer to
Pr.1299 setting
