Actual line speed analog input (Pr.362 = "3 to 6", Pr.278 to Pr.281)
• The actual line speed can be input by analog input.
• The analog input value of the actual line speed is calibrated with
Pr.278 Actual line speed voltage/current gain, Pr.279
Actual line speed gain
,
Pr.280 Actual line speed voltage/current bias
, and
Pr.281 Actual line speed bias
. The
calculation result is applied as the line speed command value (lower limit: 0 m/min, upper limit: 6553.4 m/min).
• When "9999" is set in any of
Pr.279 to Pr.281
, the settings for the corresponding line speed command (
Pr.350 to Pr.353
)
are applied for calibration. (Refer to
NOTE
• The difference between the setting values of
Pr.278
and
Pr.280
can be set within 5%. (Even if the difference is 5% or less,
Er3 (calibration error) does not occur.)
• The
Pr.280
setting can be larger than the
Pr.278
setting. Also, the
Pr.281
setting can be larger than the
Pr.279
setting.
Sampling time for winding diameter calculation (Pr.1245)
• For winding diameter calculation using actual line speed, use
Pr.1245 Sampling time for winding diameter calculation
to set how often the winding diameter calculation result is applied.
• When
Pr.1245
= "9999", a sampling time is about 5 ms for winding diameter calculation.
NOTE
• When the thickness method is selected, the
Pr.1245
setting is invalid and a sampling time is about 5 ms.
(Refer to
.)
• The sampling time in
Pr.1245
is valid also for pulse train input of the line speed command (when
Pr.361
= "2 or 7").
