A-26 OPERATION PANELS
5-6-4
Dry Run Switch [DRN]
When this switch is pressed, the indicator in the switch is
lit and the dry run function becomes valid.
When this switch is pressed again, the indicator in the
switch goes off and the dry run function becomes invalid.
<Dry run function>
The cutting feedrate specified in a program is ignored and all axis feed commands are executed at
a feedrate set using the OVERRIDE dial.
This function is used to shorten program check time.
Be aware that the program will be executed at an unexpected feedrate if the dry run
function is made valid mistakenly during automatic operation, and this could cause
accidents involving damage to the machine.
<When the dry run function is valid>
In the dry run mode, the cutting feedrates specified in the program are adjusted by the feedrate set
with the OVERRIDE dial.
The OVERRIDE dial setting can be changed in 16 steps.
Setting range: 0 to 1260 mm/min
With machines featuring the spindle OFF mode function, the dry run function is valid
during thread cutting and tapping (M type).
<When the dry run function is invalid>
All feedrates (cutting feedrates and rapid traverse rate) are executed at the programmed
feedrates. The percentage setting (0 to 150%) of the OVERRIDE dial becomes valid when the dry
run function is canceled. Therefore, be careful when making the dry run function valid and invalid.
If the dry run function valid/invalid state is changed by pressing the dry run switch
during automatic operation, the machine stops in the feed hold state to ensure the safety
of the machine and the operator. The automatic operation can be restarted by pressing
the
(START)
switch.
