RDZ01 LFS Manual
Workflow of the mixed laser cutting system is as follows。
(1) Power on Reset
When RDC633XM power on, controller OUT1 is invalid to keep the LFS not moving.
(2) Start a work
When started, RDC633XM OUT1 output low level to control the LFS moving down. When reach to the focus
point, blowing auxiliary gas and punching hole. And then executing a laser cutting. When a closed curve
element is cut, LFS will close auxiliary gas and rise up the laser head to a referenced position.
Then jump to another closed curve element to start a new cutting. After all the curves are cut, the laser head
will be moved to a higher referenced position.
(3) Pause/continue
Controller will drive the head up to the fixed height when pause. When continue, the head position will not
move if the system is paused during jumping. System will move the head down and cutting if it was paused in
laser cutting process.
(4) LFS test
When all the connections have been finished, a test of LFS can be done. Firstly check cooperation between
LFS controller and RDC633XM. Different step drivers may have different definitions on the rotate direction
according to the DIR level. Some may be CCW when DIR is high and some may be CW when DIR is high.
So a rule must be defined. Just like the follows:
During the RDC633XM is not busy and in a ready status, press “.” on the panel, the laser head should
moving down. Press again, the laser head rising up. This is the rule.
