4.4 Commissioning
Before final commissioning please check once again that all plug-in connectors are correctly
mounted and the locking screws are tight. After this you can switch on the PC and install and launch
the controller software.
Carry out the required setting of machine parameters according to the controller software
user manual.
Prior to the first test run make sure that there are no tools in the collet of the
spindle motor and no workpiece or other objects on the work surface. If
necessary, rotate the positioning drives into a safe position with sufficient
distance to the final positions. Close the covers or make sure that nobody is
present within the hazardous area.
Insert the power plug of the controller only now and switch the controller on at the main
switch.
Start by checking that the end position switches and all E-stop switches are functioning
correctly.
Check that the stepper motors are rotating in the correct direction using manual travel
(jogging) at slow speed (e.g. 1mm/s). Check whether the displayed travel path corresponds
with the path actually traversed (adjustment steps/mm).
In the event that anything fails to function as expected, switch off the machine at once and
check the connections as well as the software settings.
If all switches function as expected and the directions of movement and distances traversed
are correct, you can carry out a reference run (homing).
The machine is ready for operation. In order to familiarize yourself with operating the machine it is
recommended that, before the first “real” processing operation you allow a CNC program to run “in
thin air,“ i.e., without the tool, material or workpiece.
