Dedicated monitor function
(4) Tension adjustment
(Pr.718, Pr.719)
Operation with the X83 signal
The dancer tension command and the dancer tension command 2 are monitored by turning ON/OFF the X83 signal.
The dancer tension command is determined by the winding diameter. Set
Pr. 781
= "1" to enable the winding diameter
storage when using the dancer tension command.
If the winding diameter storage is set disabled with
Pr. 781
= "0", the winding diameter is initialized by turning ON the X83
signal, possibly leading to a sudden change in outputs. When the X83 signal turns OFF, the preceding winding diameter is
kept to calculate the outputs. Caution is required when turning ON the X83 signal.
Dancer tension setting bias/gain
Set 0% in
Pr. 718
(tension setting bias).
Set 100% in
Pr. 719
(tension setting gain).
Taper control
When no analog input terminal is assigned (
Pr. 787
=
"9999"), the taper setting becomes 0.
When
Pr. 789
= "9999", an input value to the analog
terminal is set to the tension setting T*. The analog
terminal is assigned by
Pr. 734
. Analog values are clamped
between 0 and 100.0.
If no analog input terminal is assigned because of a
prioritized function or
Pr. 734
= "9999" setting, etc., the
tension setting T* is set to "0".
