WINDING DIAMETER COMPENSATION FUNCTION

Winding/unwinding length detection (Pr.1264, Pr.1346, Y234 signal)
• When the material winding (unwinding) length is equal to or more than the length determined by the settings of
Pr.1264
Winding length detection (lower 4 digits)
and
Pr.1346 Winding length detection (upper 4 digits)
, the Winding/
unwinding completion (Y234) signal turns ON. Use
Pr.1262 Winding length increment
to set the winding length
increment.
• For the Y234 signal, set "234 (positive logic) or 334 (negative logic)" in one of
Pr.190 to Pr.196 (output terminal function
selection)
to assign the function to the output terminal.
Winding diameter / winding length storage selection (Pr.645)
• Use
Pr.645 Winding diameter storage selection
to select the timing to update the values of winding diameter (
Pr.646
)
and winding length (
Pr.1263
and
Pr.1298
).
∗1
If the power supply is disconnected, the winding diameter may not be stored. To make sure that the winding diameter is stored, turn OFF the
X114 signal to store the diameter before turning OFF the power.
∗2
When the FR-HC2/FR-CV is used, the winding diameter is stored using the X11 signal. To make sure that the winding diameter is stored, use
the X11 signal.
NOTE
• The winding diameter is kept independently of
Pr.645
setting when start commands (STF, STR) are OFF.
• The winding diameter calculation is used or not used depending on the status of the Tension control selection (X114) signal,
Pr.1247 Winding diameter change increment amount limit
setting, and a prioritized operation such as JOG operation.
Stored winding diameter (Pr.646, Pr.647)
• Read
Pr.646 Stored winding diameter
to check the winding diameter presently stored.
• The stored winding diameter can be changed by overwriting the setting value in
Pr.646
with a desired value.
• The present winding diameter is kept for the duration set in
Pr.647 Operation time with stored winding diameter
after the
start command is given.
Pr.645
setting
Winding diameter storage timing
(Pr.646 update timing)
Winding length storage timing
(update timing for Pr.1263 or Pr.1298)
0
• When a value is set in
Pr.646
• When the Stored winding diameter clear (X109) signal is
turned ON
• When a value is set in
Pr.1263 or Pr.1298.
• When the Winding length clear (X117) signal is turned ON
1
In addition to the above-mentioned update timings defined for the setting value of "0", the stored values are also updated at the
following timings.
• When the enabled winding diameter calculation is disabled.
• When the power is turned OFF while the winding diameter calculation is valid (when the power is supplied through the main
circuit terminal (
Pr.30
= "0, 1, 20, 21, 100, 101, 120, or 121"))
• When the X11 signal is turned ON while the winding diameter calculation is valid (when the power is supplied through terminals
P/+ and N/- (
Pr.30
= "2, 10, 11, 102, 110, or 111"))
Initial winding diameter
calculation
Operation at start
With initial winding diameter
calculation
The present winding diameter is kept for the duration set in
Pr.647
after the start command is given and
initial winding diameter calculation starts.
However, when initial winding diameter calculation is completed before the
Pr.647
setting time elapsed, the
result of the calculation is used.
Without initial winding
diameter calculation
The present winding diameter is kept for the duration set in
Pr.647
after the start command is given and the
winding diameter calculation starts.
