Test of spindle and cooling.
At this stage, almost all major elements of the system were set and a machine is almost ready to
work. One important issue left – spindle test. Treatment with non-rotating spindle is generally not a
good idea.
Mach should be in active mode. The quickest way to test the spin-
dle is MDI mode. In the top bar press MDI. This mode lets you to
enter G-Code commands manually:
•
Enter S command, with requested spindle revs e.g.
„S2000” – that is 2000 rpm speed. Approve with <en-
ter>.
•
Enter M3 command (right revs) and approve with
<enter>. The spindle should start rotate right with re-
quested speed.
•
Enter M5 command (stopping) and approve with <enter>. The spindle should stop.
•
Enter M4 command (left revs) and approve with <enter>. The spindle should start rotate
left with requested speed.
•
Stop with M5 command.
•
Turn on cooling with M7, turn off - M30.
•
Turn on cooling M8, turn off - M30.
It is good to check various revs values and revs change from maximal revs to very low. If you do not
use a braking resistor at inverter it may turn out that, when braking at high revs speed – the inverter
will report an error. Then you have to get yourself a resistor or lengthen the braking time.
In case of any problems, check again configuration settings and eventually the inverter settings. Usu-
ally the inverters have various control modes. Without proper configuration, the inverter will not
respond to outside signals.
Before spindle activation make sure if there is no loose collet. When braking at high revs speed the
tightening nut may unscrew and rotating collet may cause injury risk.
