When OPEN (SHORT) is specified, change the stroke change signal
(general output) to short open; when FULL OPEN (LONG) is specified,
change the stroke change 1 signal (general output) to full open. However,
the stroke change signal ON/OFF characteristics depend on the AP
parameter setting.
For the use of C double gun, X double cylinder gun with
double solenoid specifications:
SUPPLE-
Set signal numbers for stroke change 1 and 2 in the spot I/O

allocation information window. The inverse signal of stroke
change 1 is output as stroke change 2 signal.
Stroke change signal (output) is output with double solenoid
specifications. The stroke change signal ON/OFF characteristics depend
on the AP parameter setting.

When pressure detection is OFF, stroke is changed
after elapse of stopper type stroke short open output
delay time.
Manipulator moves immediately without detecting
when short open detection is OFF.
