PC NC Maintenance Manual Chapter 5: Adjustments
5-2
Output voltage Verify the output voltage after initially applying the power. Press the POWER
ON button for the first power application, and verify the following:
• Normal air flow from the cooling air exhaust port
• Sufficient output voltage of the composite power supply unit, as noted
below
I/O signals Verify the I/O signals between the NC and machine tool are sufficient.
Emergency stop Verify that the second power supply (i.e., servo power supply) is turned off
and that the alarm display “3002: Emergency Stop” appears when the emer-
gency stop is activated.
Axis movement Observe movement on each axis during manual feed, and verify the follow-
ing:
• Machine tool properly corresponds to movement made by the handle
or step feed.
• Machine stops following detection of an overtravel alarm, following
activation of the OT limit switch during manual jog feed.
• Machine tool accurately follows in the entire feed rate range in man-
ual jog and rapid traverse rate.
All NC functions Verify that all NC functions activate successfully.
