Spindle rotation should stop. The emergency stop button is the most important
safety switch on the machine. It stops and then de-energizes the spindle motor.
(At the same time, it stops and de-energizes the axis servo motors, although they
are not running for this test.)
When the red emergency stop button is pushed, the spindle should brake to a
rapid stop. If the spindle does not stop at all, or if it coasts to a stop, then the
emergency stop circuit is not operating correctly. Call qualified service personnel
(as described in chapter 1) to fix the problem. The machine should not be
operated until the emergency stop circuit is operating correctly.
Repeat the same tests using all emergency stop buttons including conveyor,
remote hand controller, etc.
Test the enclosure safety circuit (CE machines only)
If the machine is still in emergency stop mode from the previous test, then twist the red
EMERGENCY STOP button clockwise to release it. Press the ENABLE button to re-
energize the axis motors and the spindle motor. Follow the directions in the previous
sequence for starting the spindle for manual use.
Now hold in the SETUP button and open the door to the machining enclosure (if
equipped). The spindle should brake to a rapid stop. If the spindle does not stop at all,
or if it coasts to a stop, then the enclosure safety circuit is not operating correctly. Call
qualified service personnel (as described in chapter 1) to fix the problem. The machine
should not be operated until the enclosure safety circuit is operating correctly.
Never operate the machine with the “door open” parameter turned off, or with the
operation of the door switch defeated.
