RDZ01 LFS Manual
Picture5-3 Parameter setting interface of LFS controller
Note:
Before write or read parameters, the LFS must be in idle status or in work finish status. And then switch the
work mode to manual mode. So user can write or read parameters.
Do not read or write into the LFS during the LFS is in busy status. When the LFS or the LFS is on the work
finishing state, the parameters can be read or wrote.
Parameters include of:
l Filter parameters（parameter1，parameter2，parameter3）：
The parameters are for LFS control. The initial value is 100,0,0 in default. These parameters have
effect on the sensibility of live focus control. If the parameters are set incorrectly, the LFS may occur
vibration.
l Height for jump
When starting a cutting task, laser head will jump from a vector to another vector. The height is the
rising up height when jumping. Usually the value is set to be less than 10mm.
l Height for crash alarm
When the laser head has crashed to the metal surface, the LFS will rise up the laser head to prevent
the laser head from damage. The rising up height is the value. 20mm is the default value.
l Height for finishing work
When all the work has been finished, the laser head should stay a higher position. So user can set the
height according his need. The value is 40mm in default.
l Focus position
Focus position is the height from the metal surface to the nozzle. Usually the value is set to be 1mm.
l Z axis step length
The step length is the ratio of the PPR and the pitch of slew. The unit is mm.
The step length must be set correctly.
l Velocity limit
The maximum velocity that LFS allows during motion control. If the step motor lose step, the value
