WEB_27 Tension Enb : Setting of Tension Control Enable Function
This is the function of conducting On/Off of the final output of PID controller. If the multi-function input terminal
(I/O_01 ~I/O_07)
set to “TensionDisable” is
Off, and WEB_27 Tension Enb becomes
“Enable”
, PID controller
operates. In any other case, PID controller
doesn’t operates any longer.

1)
WEB_28 PIDRef Sel : PID Reference Type Setting
When loadcell is used at the time of tension control, PID controller controls actual tension. Accordingly, the
reference input of PID controller should be the output of taper computation. Therefore, the set value of WEB_28
PIDRef Sel in the tension control where loadcell is used becomes
“Taper Out”
. If dancer is used, it controls the
actual dancer position where the set value of WEB_28 PIDRef Sel is
“Dancer Pos”,
and in this case to carry out the
tension control of web, you need to set one of analog outputs (AI/O_74 AO1 Define, AIO_79 AO2 Define) to
“Tension Out”
, and then connect it with dancer. At this time WEB_29 Dancer Pos becomes the reference input of
PID controller.
