LFS-PM-T43 operating manual 1
Chapter 1 Introduction
1.1 Product introduction
LFS-PM-T43 is a automatic distance control system that based on the capacity
sensor. This system has a 4.3” TFT touch screen and can display the work status and
detecting capacity value. An advanced capacity detecting technology has been
applied to have a stable and anti-interference capacity result. With this sensor
detecting technology, the responsibility and accuracy have been improved. The key
functions are just like following:
1) Control servo or step motors, high responsibility and accuracy。
2) Support crash alarm, limit trigger protection and servo alarm protection.
3) Automatic calibration and can compatible with the third party’s laser head.
4) Support focus distance modified on line. capacitor detecting scale is
0~9.9mm.
5) Work status of the laser head indicates and alarm indicates.
6) Support different setting of the rising height. Rising speed can be modified.
7) Auxiliary gas control. Support 3 channels auxiliary gas control。
8) Firmware updated by U disk。

Chapter 2 Functions
1.2 4.3”touch screen
This distance controller is included of a 4.3” touch TFT screen. The resolution is 480X272.
the laser head work status is displayed in the monitor and parameters can be modified with the
monitor. the display area is function button area, data display area, running status display area and
alarm display area.
The main interface is just as the following:
⚫Function button area：touch the buttons can enter different function control menu.
⚫Data display：here is used to display the detecting value of the capacitor sensor and other
set values。
Focus position：the distance between the nozzle and the work piece.
Actual position：the actual value of the capacitor detected.
Following error：the error between the focus position and the actual position.
Capacitor value：the value that the controller has detect from the capacity sensor；
⚫Running status ：display the status of the laser head.
⚫Alarm display：alarm status display. If there are several alarm triggered at the same time,
user can touch the “alarm info”to check the alarm information in detail.

Main interface
The communication between the the controller and the touch screen monitor is by RS232.

LFS-PM-T43 operating manual 3
If all the electrical connections has been done correctly, when power on the controller, the
monitor of the controller will go to the main interface. If there are no error happened, that means
the automatic distance controller work well.
But if the monitor indicate that connection failed because of the cable fault or other
reasons，”connection failed” will be popped up. User should check the cable and the sensor
devices.
1.3 Control functions
2.2.1 Main interface introduction
◆“tracing on/off”：Enable or disable the tracing function. If it is tracing on, the color of
the button will changed into green, which means the controller is under the tracing
status. If the height of work sheet changes, the laser head will tracing the movement of
the work sheet and always keep the distance to be a constant value. If it is tracing off,
the tracing function is disabled. If the height of the work piece changes, the laser head
has no response to that during the motion of the cutting system.
◆“fast/slow”：is used to switch the manual speed to faster or slow.。
◆“menu”：there are children menus in the menu to set some functions.
◆“reset”： To reset the distance controller. Before running reset function, be sure that
the upper limit has been installed correctly.
NOTICE: There is danger during the reset operation because of the mechanical motion.
So all the section should be checked before that and try to avoid of human harm.
◆“±0.1”：modify the distance between the nozzle and the work sheet. Press one time,
0.1mm will increase or decrease 。
◆“move up、move down”： to control the laser head to move up or move down. If the
button is pressed, the laser head will be always moving until the button is released.
◆“alarm info”： Press the button; user will go to the alarm information records interface.
User can check the alarm information that happened recently. The maximum number of

LFS-PM-T43 operating manual 4
the alarm record is 9.
◆“Function”： go to the auxiliary gas test and capacitor calibration menu
◆“system info”：check the version of the controller and multi-language
selection.
◆“system time”：modify the system time。
2.2.2 Parameter setting
Press“menu”to enter the interface of craft parameter setting, height parameter setting,
velocity parameter setting, machine parameter setting and other parameters.
Notice : Before operating the distance controller, be sure that the parameters has already set
correctly.
The sense of the parameters is shown as the table：
Control
PID filter
Increase the value will improve the responsibility of the
laser head.
Alarm time
Filter time for crash alarm protection. If the value is too
small, the crash alarm will usually triggered because of the
metal dross during cutting. If the value is too big, this will
decrease the responsibility of the crash alarm protection.
Gas delay
Auxiliary gas release time before cutting or piercing.
Pierce gas
Auxiliary gas selection for piercing.
Cutting gas
Auxiliary gas selection for cutting。

Height
Rise posi
The rising height for laser head during jump motion。
Alarm posi
When the alarm triggered, the laser head is on the stop
height
Stdby posi
When the cutting task is finished, the laser head is on the
position.
Focus posi
The distance between the nozzle and the work piece
Reset posi
When reset the laser head, the laser head will trigger the
limit switch and move reversely for this distance
Follow error
During a close control, the error between the actual position
and referenced poison should never beyond the value. If that
happened, system protection will be executed and generate
the alarm of following error over limit

Crash En
If the crash alarm is enabled, when the laser head has touched
the work piece for a certain time(over the filter time), system
will rise up the laser head and stop the motion of the cutting
system
If it is disabled, the crash alarm will be neglected.
Lmt SNS
Set the sense of the limit switch. If a NPN limit switch is

installed, user should set the polarity to be negative. If it is
PNP, the polarity should be set to positive.
LMT EN
If the limit protection is enabled, when the limit is triggered,
the motion protection will take affect such as rising the laser
head and stop motion.
2.2.3 Parameter management
Parameters management is used to save and restore the parameters of the distance controller.
Not everybody can operate this function. There are passwords for user to manage this function.
When user has configured all the parameters correctly, then these parameters can be set to be
default. So if the parameters have been changed, user can restore the right parameters from the
default. We suggest that user must save the correct parameters to be default when all the
parameters have been tuned correctly.
2.2.4 Alarm information
On the main menu, press “ALM INFO”to go to “ALM INFO”interface.
User can check the alarm information. The information include of the alarm time and alarm
source. The maximum records are 9 records that is saved. Press the “clear”, all the information is
cleared. User still can press “page up”or “page down”to check the information.
