PLMNL0199 REV. J Effective Date: 08/05/21 1FiberCUT®ST Operation Manual
1 Introduction
The FiberCUT®robotic laser processing head
was developed to work in the most extreme
manufacturing environments. The straight input
of all connections, including the fiber, optimizes
the ability of the robot to utilize its complete
working envelope.
The FiberCUT®is made up of four main
subassemblies. See Figure 1:
The robotic mount
The fiber collimator assembly
The drive mechanism
The tip retainer assembly
See Figure 2 for the path of the laser beam
through the FiberCUT®. The robotic mount
connects the cutting head to the robot, often
through an optional collision sensing device. The
fiber collimator unit uses a doublet collimating
lens to gather the laser light and collimate it after
it leaves the fiber optic cable.
A collimator focal length of 100mm is
standard (other focal lengths are available if
the application requires).
The laser beam then propagates through the
final focusing lens which focuses the laser
through the orifice of the gas jet tip. The drive
assembly provides the motion system that
allows the tip to track the surface of the part and
maintain laser focus.
The drive system has 25mm of travel and is
controlled by a patented drive system which
provides smooth, linear motion.
The tip retainer assembly contains the final
focusing lens and a cover glass that protects the
lens from dirt and debris. The lens housing is
threaded into the tip assembly.
The tip threads into the end of the tip
retainer and controls gas flow to the work
piece.
The tip retainer assembly also provides the
electrical feedback to maintain a constant
gap between the tip and part.
The tip retainer assembly comes in various
focal lengths and configurations, allowing
the end user to optimize the cutting head
configuration.
This manual explains the steps of installing,
setup, operation and service of a FiberCUT®
robotic laser.

2 Installation –Mechanical
2.1 Robotic Mount
The robotic mount attaches to the robot
and can provide optional collision sensing
to protect the cutting head during a crash.
See Figure 3. The collision sensor mounts
to the robot using an adapter plate. The
appropriate hardware will be provided with
the cutting head determined at the time of
sale.
Figure 3
The optional collision sensor (sold
separately as part number PLCPD0084) is
a pneumatic device.
The sensor requires 6mm OD hose.
The recommended operating pressure
for the collision sensor is 1 BAR, but
can vary depending on application.
The hoses need to be suitable for
robotic applications.
2.2 Mounting the Cutting Head to the
Robot Mount Bracket
The standard bracket holds the head in a
vertical orientation. The bracket bolts onto
the head using four M6 SHCS and is
positioned on two dowel pins (see Figure
4).
Figure 4
There is also a mount pattern on the back
side of the head to mount cable
management blocks to the robotic cutting
head. See Figure 5 for mounting pattern.
Figure 5

PLMNL0199 REV. J Effective Date: 08/05/21 3FiberCUT®ST Operation Manual
2.3 Plumbing –Water Cooling /
Assist Gas / Purge Gas
All lines must be suitable for robotic
applications and are supplied by the
integrator.
See Figure 6 for line locations.
The water cooling lines require 6mm
OD hoses. Cooling specifications are in
Appendix A.
Assist gas recommendations:
oA proportional gas valve placed
within 8 feet (2.5 meters) of the
FiberCUT®head.
o8mm OD hose between the
proportional valve and the
FiberCUT®head. The cutting head
includes a short flexible hose. Do
not remove the hose unless you
replace it with an equivalent unit.
oWhen the gas source is less than
25 feet (7.5 meters) away from the
FiberCUT®head, route 8 mm OD
hose between the gas source and
the proportional vale.
oWhen the gas source is over 25
feet (7.5 meters) away from the
FiberCUT®head, route 3/8 inch OD
(minimum) hose between the gas
source and the proportional valve.
oSpecifications for assist gas are in
Appendix B.
oThe assist gas line must be rated
higher than the maximum expected
pressure.
oFor systems that use oxygen (O2),
verify that valves, fittings, and
hoses are compatible.
The purge gas line requires 6mm OD
hose. The cutting head includes a
particle filter and two short flexible
hoses. Do not remove the filter and
hoses unless you replace them with
equivalent units. Specifications for
purge gas are in Appendix C.
Figure 6

PLMNL0199 REV. J Effective Date: 08/05/21 4FiberCUT®ST Operation Manual
2.4 Fiber Input
The fiber input is where the fiber optic cable
plugs into the cutting head. See Figure 6.
There are several industrial standard styles
of fibers ends (QBH, QD/LLK-D, LCA,
Q5/LLK-B, HCL-8 & PIPA). See Appendix
Dfor sample images of each. Each of
these fibers has a unique method of
securing it to the fiber input adapter. Refer
to the fiber manufacturer’s information for
specific instructions.
2.5 Bundling
As in any robotic application, cables need
to be bundled in a manner allowing
complete tool movement without pinching
or pulling of the cables. The FiberCUT®
head was designed so that all cables input
in the same location –allowing a sleek,
easy-to-manage bundle.
Cabling should not be tethered to the fiber
input connector or the fiber optic cable.
The manner in which the cables are
bundled is one of the keys to having
a successful robotic cutting cell. The
end user is responsible for
documenting and training personnel
on the best bundling methods for
their application.
2.6 Electrical Wiring
There can be two electrical wires
connected to the cutting head. See Figure
7.
One is the communication cable
between the cutting head and the
control box (PLCAB0489).
The other is the optional collision
sensor cable that is plugged into the
robot system interlock (PLCAB0488).
Figure 7

PLMNL0199 REV. J Effective Date: 08/05/21 5FiberCUT®ST Operation Manual
2.7 Electrical Grounding and Noise
The capacitive sensing circuitry contained
in the FiberCUT®cutting head measures
minute changes in electrical capacitance
between the tip and earth-ground to
determine tip-to-part standoff distance. In
order for this circuit to function properly,
connect the part and the cutting head to a
good earth ground.
Ideally, establish the ground from a
ground rod, approximately 2 meters in
length driven into the ground located
near the base of the robot.
Run a large gauge (1.6mm diameter or
larger) ground wire from the ground rod
to the part.
Run a separate wire from the ground
rod to the mount of the FiberCUT®at
the end of the robot. See Figure 8.
Figure 8
Electrical noise can create sensing issues.
Large electric motors, arc welders and
other devices may be a source of
significant electrical noise. In order to
eliminate this noise it may be necessary to
connect a ground wire to the chassis of any
such device near the process.
2.8 Control Box Mounting
The important things to consider when
mounting the control box are:
Clearance to attach connectors
Clearance to open the control box door
Standard cable length is 15 meters
Easy access for maintenance.
Mounting such that debris from the
process is not directed at the controller
box.
Mounting in an area where there are no
water leaks or oils from hydraulic
presses.
Figure 9 illustrates the control box
mounting pattern.
Mounting screw heads are located
inside the control box.

3.3.2 Teach / Center of Travel (COT)
The COT input sets the head in the
fixed center of travel position. When
teaching the motion system path, it is
preferable to have the FiberCUT®
head in the COT position.
At the COT position, the decal on
the telescoping tube will have half
of the green section exposed. See
Figure 15.
Figure 15
COT has precedence over HS1,
HS2 and HS3.

PLMNL0199 REV. J Effective Date: 08/05/21 9FiberCUT®ST Operation Manual
3.3.3 Programmable Retract Position
The FiberCUT®controller has the
ability to position the head at seven
different retracted positions. To
enable this feature, click the check
box for Prog. Retract Positions in the
Preferences of FiberCUT®Monitor.
See Section 5.6.
Once enabled, you can activate this
feature by simultaneously activating
the COT (Center of Travel) and a
combination of Height Select Bits.
The •symbol indicates ON.
When the head reaches the
programmable retract position, the
RET-POS (Retracted Position) output
becomes active. This feature can
reduce cycle time by minimizing the
amount of travel the head has to
move in-between cuts.
Note: The FiberCUT®controller does
not perform a height sensor
calibration when using this feature.
3.3.4 Motion Inhibit (HOLD)
The HOLD input holds the head at the
current position regardless of the
measured standoff height.
HOLD is useful when the cutting
path must start in a location that is
not over the work piece.
HOLD has precedence over HS1,
HS2, HS3 and COT.
See Section 4.3 for more details.
3.3.5 Tip Select Bit (TSB)
The TSB input allowed selection of the
type of tip installed on the head in
early controller versions. The
FiberCUT®Controller Firmware
Update PC software replaced this
functionality. The tip select bit should
remain off unless otherwise instructed.
See Appendix F for more information.
3.3.6 Analog Input Enable (AIE)
When AIE is active, ANALOG-IN
controls the standoff height.
With AIE inactive, HS1, HS2 and
HS3 set the standoff height.
If AIE, HS1, HS2 and HS3 are off,
the head will retract unless COT
or HOLD is active.
3.3.7 Reset/Servo Disable (RST)
RST allows you to reset the head
if a fault occurs.
When RST is activated, the Crash
output will be active and the
FiberCUT®will fully extend. Once
RST is deactivated, the
FiberCUT®will fully retract and
recalibrate. If RST is held active,
the FiberCUT®servo motor will be
disabled and the head will fully
extend.
3.3.8 Input Common (IN-COM)
Connect +V to IN-COM when the
inputs are connected to sinking
(active low) outputs.
Connect 0V to IN-COM when
connecting to sourcing (active
high) outputs.

range is 1V to 4V (1V=>0.5mm;
4V=>2.0mm).
3.4.2 Analog Output (ANALOG-OUT)
0 to 5VDC
There are 5 different output
options available. See Section 5.6
for setting the preferences.
1. HSU Voltage:
A non-linear voltage representing
the stand-off distance between the
tip and work piece.
2. Linear Pot Voltage:
A linear voltage representing the
physical position of the FiberCUT®
drive mechanism.
3. Electronics Temperature:
A voltage indicating the
approximate temperature of the
electronics contained in the head
(°C = V x 10).
4. Collimator Temperature:
A voltage indicating the
approximate temperature of the
collimating lens (°C = V x 10).
5. Lower Assembly Temperature:
A voltage indicating the
approximate temperature of the
FiberCUT®focus lens and cover
glass area. (°C = V x 10).
The temperature reading is
NOT for the nozzle assembly
alone.
3.5 Digital Outputs
Specifications: 5 to 24VDC, 250mA per
output
All outputs are configurable for
sourcing or sinking depending on the
connection made to OUT-COM.
3.5.1 In-Position (IN-POS)
IN-POS indicates that the tip is within
range of the selected standoff height.
Typically IN-POS provides a
handshake back to the motion system
that the tip has reached the part and
is ready to begin processing.
3.5.2 Retracted Position (RET-POS)
RET-POS indicates the head is at the
retracted position. Typically, RET-
POS provides feedback to the motion
system indicating the head is parked
at the retracted position.
3.5.3 Tip Touch (TIP-TOUCH)
The TIP-TOUCH signal indicates that
the tip has electrically contacted the
part or an object. This can occur
during normal processing and does
not produce a fault.
3.5.4 Crash/Fault (CRASH)
CRASH indicates that the head is
currently in a crash or fault condition.
Check the STAT1 –STAT4 for
information about the crash.
3.5.5 Output Common (OUT-COM)
Connect +V to OUT-COM for
sourcing (active high) outputs
Connect 0V to OUT-COM for
sinking (active low) outputs.

3.5.6 Fault Code Status Bits
The •symbol indicates ON.
*Automatic Sleep Mode
While in sleep mode the
FiberCUT®disables its servo
motor and the head fully extends.
All of the status bits (STAT1,
STAT2, STAT3 and STAT4) will be
active but the crash output will
remain inactive indicating the
FiberCUT®has entered sleep
mode.
Set up automatic sleep mode
according to Section 5.6.
Retract on Fault (ROF)
By default, the head will extend
whenever a fault occurs.
When Retract On Fault is
selected, the head will instead
retract when a marked fault
occurs. To configure this option,
See Appendix F.
3.5.7 Crash Interlock Relay (INT1,
INT2)
Solid State Relay Rating:
500mA at 0-60VDC, 0-
48VAC
A solid-state relay opens to
indicate a fault or crash
condition on the cutting
head.

3.7 Ethernet Interface (P3)
The Ethernet port provides a means of
interfacing to the FiberCUT®controller with
all of the capabilities of the discrete I/O with
the addition of fault descriptions. Connect
the Ethernet port (P3) to your motion
system using a crossover or null modem
Ethernet cable, or to a network hub by a
straight through Ethernet cable. The
assigned controller IP Address is
169.254.99.12. A standard Windows Telnet
session can connect to the controller. See
Figure 17.
Note: The commands and
inquiries interact directly with the
program running on the LM/Galil
controller. Unintentional alteration
of the program may result if
improper instructions are given.
Take care the commands to the
controller are accurate.
(Refer to Galil RIO-47IXO User
Manual for additional
information.)

3.7.1 Simulating Inputs (i1 –i8)
The variables i1 –i8 are used to
simulate the discrete inputs by
assigning the variables a value of 1 or
0.
Examples:
i1=0; i2=0; i3=1 - Sets the standoff
height to 1.25mm.
i5=1 - Turns on motion inhibit.
i5=0 - Turns off motion inhibit.
3.7.2 Simulate Analog Input (anlg)
The variable anlg simulates the
external analog input by assigning
values to the variable using the same
rules as the external analog input. The
standoff height is set with a value of 1
–4, which gives a corresponding
standoff value of 0.5mm to 2.0mm.
Examples:
i7=1 - Activates external analog input.
anlg=2.5 - Sets the standoff height to
1.25mm.
