should be decrease.
l Auto-searching focus velocity
During auto-searching focus point, the laser head move down to metal surface with this velocity.
The perfect value is from 1mm to 5mm. 3mm is the default value.
l Motor rotation polarity
To change the moving direction during auto-searching focus position. When the laser head rising up
during auto-searching focus, the parameter should be modified to ensure that that laser head move
down to the metal surface. The default motor polarity is negitive.
But there is another way to do this. If the laser head moving direction is not the desirable condition,
the A+ and A- can be exchanged to change the moving direction.
l Limit enable and the limit polarity
There are negative and positive limit inputs for protecting laser head during motion. If the limit is
enabled and limit polarity is set correctly, the LFS will protect the laser head. During live focusing,
the laser head touch the down limit; the laser head will rise up to a safe position. During rising up, if
the upper limit is touched, the motor will stop motion immediately.
If the limit switch is normally open, one terminal connects to GND. Another terminal connects
to limit input of LFS. The parameter named limit polarity should be set to be negative.
If the limit switch is NPN, The parameter named limit polarity should be set to be negative.
l Crash alarm enable
If crash alarm is enabled, laser head will rise up to the crash alarm height when the laser head touches
the metal surface. If the cash alarm is disabled, the crash alarm input will be neglected.
l Auxiliary gas control
The LFS supply 3 IO to control auxiliary gas. OUT2 is for the O2 with high pressure. OUT5 is for
the compressed air. OUT4 is for the O2 with low pressure.
During metal cutting, when punching hole, OUT4 is open for low pressure O2 and OUT2 is
closed. After punching hole, the OUT2 is open and the OUT4 is closed for cutting.
When switching to manual mode, air channel is enabled. Out2 and out4 is closed. Out5 is open.
Open the LFS parameter configuration interface. Switch to manual mode and press the button “open USB”.
If the USB is opened correctly, the “read parameter” is enabled. If the USB connection is fault, the button will be
always disabled.
First, parameters should be read. Then the parameter can be wrote into the LFS. See picture 5-4.
