2. SIGNAL DESCRIPTIONSHANDLING
51
NOTE
It is also possible to start operation at the rising edge (from
off to on) of the ST signal as specified by the STON
parameter (bit 7 of parameter No. 003).
(2) Automatic operation start in--progress signal STL
[Classification]
Input signal <Xx+1#5> (common to both the peripheral equipment
control and direct command interfaces)
[Function]
This signal indicates that automatic operation has been started.
[Input condition]
The signal becomes 1 when a command to start automatic operation
is issued. It becomes 0 when automatic operation stops.
(3) Automatic operation signal OP
[Classification]
Input signal <Xx+1#7> (common to both the peripheral equipment
control and direct command interfaces)
[Function]
This signal indicates that a series of automatic operations is in
progress.
[Input condition]
The signal becomes 1 when a command to start automatic operation
is issued. The signal remains set to 1 even after automatic operation
stops. It becomes 0 upon the occurrence of a reset.
(4 ) Dry run signal DRN
[Classification]
Output signal <Yy+7#6> (peripheral equipment control interface)
<Yy+2#6> (direct command interface)
[Function]
Dry run is valid during automatic operation (AUTO mode). During
dry run, a feedrate command issued during automatic operation is
ignored, and a manual--feed feedrate determined by override signals
*OV1 to *OV8 ((1) of Section 2.3. 7) is used. Dry run is also valid for
rapid traverse. When the R T signal ((2) of Section 2.3.7) is set to 1
during dry run, the ”rapid traverse rate” and the ”maximum
manual--feed feedrate” are used for the rapid traverse and cutting feed
blocks, respectively. When the R T signal is reset to 0, the ”same rate
as the manual--feed feedrate” is resumed.
[Operation]
Setting the DRN signal to 1 causes the system to enter t he dry run
state. Resetting it to 0 resumes the feed rate specified during
automatic operation.
