Winding diameter calculation setting

WINDING DIAMETER COMPENSATION FUNCTION
Actual line speed input selection (Pr.362)
• Use
Pr.362 Actual line speed input selection
to select the input method for actual line speed to perform winding diameter
calculation.
• When material thickness is set to
Pr.1231 Material thickness d1
(
Pr.1231
≠
"9999"), calculate winding diameter not from
line speed but from the product of material thickness and number of rotations of a roll. (Refer to
.)
∗1
When
Pr.362
= "9999" (no function), the line speed command is regarded as zero.
∗2
When
Pr.362
= "2", use
Pr.862
to select the option used for the actual line speed input. (Refer to
.)
∗3
The input specification in the initial setting is indicated.
NOTE
• The priorities of the input signals are defined as follows. If the input method for a signal is the same as that for the input signal
with higher priority, the signal with lower priority does not work.
Dancer signal input (
Pr.363
) > Actual line speed input (
Pr.362
) > Tension command input (
Pr.804
) > Line speed command
input (
Pr.361
≠
"0") > Taper setting input (
Pr.1285
) > Dancer tension setting input (
Pr.364
) > Line speed command
compensation input > Line speed command input (
Pr.361
= "0")
Actual line speed unit (Pr.358)
• Use
Pr.358 Line speed unit
to select the unit of the line speed.
Actual line speed input by pulse train input (Pr.362="1, 2, 7", Pr.279,
Pr.281 to Pr.284)
• The actual line speed can be input using single phase pulse train input through terminal JOG, encoder pulse train input
through FR-A8AP/FR-A8AL/FR-A8TP, or single phase pulse train input through FR-A8AL (PP, NP).
• The number of pulses is calculated internally as follows.
∗1
Use
Pr.428 Command pulse selection
to set the pulse train type. (Refer to
.)
∗2
To perform Vector control, install the Vector control compatible option.
• The actual line speed input by pulse train input is calibrated with
Pr.279 Actual line speed gain
,
Pr.281 Actual line speed
bias
,
Pr.282 Actual line speed pulse input bias
, and
Pr.283 Actual line speed pulse input gain
. The calculation result
is applied as the actual line speed input value (lower limit: 0 m/min, upper limit: 6553.4 m/min).
• When "9999" is set in any of
Pr.279
or
Pr.281 to Pr.283
, the settings for the corresponding line speed command (
Pr.351
, or
Pr.353 to Pr.355
) are applied for calibration. (Refer to
• For the actual line speed input using pulse train, use
Pr.284 Actual line speed input filter time constant
to set the time
constant of primary delay filter for pulse train input. When
Pr.284
= 0 s, the filter is not set.
