1.3.2.1 GUNCL Instruction
This is the dry spotting instruction. It performs dry spotting for the
specified time. The gun performs dry spotting then returns to the start
position after the time-up timer counts out. Use this instruction when
spotting is required, such as after automatic tip dressing or automatic tip
replacement.
Additional Items
(1) Gun# (X)
Specifies a gun to be pressed.
(2) T = X
Specifies the time when the gun is closed.
(3) ATT = X
Starts execution of GUNCL X second(s) before reaching the move
instruction located immediately before it. However, it is necessary
to specify “NWAIT” to the move instruction immediately before the
GUNCL instruction.
NOTE
Be sure to use this instruction in the short open status with
a double stroke gun other than X double stroke mechanical
stopper type gun.
The instruction controls only one gun at one time. Two
guns cannot perform dry spotting simultaneously. When
GUNCL instruction is executed, it takes a time for the stroke
action and dry spotting time is shortened.
