CAUTION
Ensuring safe operation
•Be sure to turn off the power to the LK-G5000 Series and connected devices when you
connect/disconnect the cable to/from them. Failure to do so may result in product
damage.
•Do not turn off the power while any item is being set. Part or all of the settings may be
lost.
•Do not block the vent holes on the unit. The rise in the internal temperature may cause
product failure.
Installation environment
To use the LK-G5000 Series properly and safely, avoid installing it in the following
locations. Doing so may lead to product breakdown.
•Location that is humid, dusty or poorly ventilated
•Location where the temperature becomes high, such as a place exposed to direct
sunlight
•Location where there are flammable or corrosive gases
•Location where the product may be directly subjected to vibration or impact
•Location where water, oil or chemicals may splash onto the product
•Location where static electricity is readily generated
Noise control
When the LK-G5000 Series is installed near a noise source such as a power source or
high-voltage lines, noise may cause a malfunction or failure of the unit. Take corrective
actions against noise by using noise filters, laying cables in a separate conduit, and/or
providing insulation when installing the controller and sensor head. Use a single core
shielded cable for the analog output cable.
Influence of ambient temperature
Changes in the ambient temperature may cause the measurement to fluctuate. Be sure to
keep the temperature constant at all times. When the ambient temperature changes by
10°C, it takes about 60 minutes until the temperature inside the unit is uniformly
distributed.
Ambient light
Do not use the LK-G5000 Series near a lighting system that repeatedly turns on and off
rapidly. If it is unavoidable to use the unit in such a place, install a light shielding board or
a similar object so that the light will not affect the measurement.
Warming up
After turning on the power, wait approximately 30 minutes before using the LK-G5000
Series. Since the circuit is not stable immediately after the power is turned on, the
measured value may gradually change during this period.
5
Influence of dust or dirt
The measurement may be incorrect when dirt, dust or fluid such as water or oil interferes
with measurement in the following ways.
•Adhesion on the protective glass: Blow the dirt off with clean air. If dirt persists, wipe the
glass surface gently using a soft cloth moistened with alcohol.
•Adhesion on the surface of the measurement target: Blow the dirt off with clean air or
wipe it off.
•Intrusion of floating dust or splash of fluid into the light-axis range: Take corrective
action such as installing a protective cover or air purge.
Other considerations
Influence of vibration
When the measurement target is vibrating, the measured value may fluctuate. In this case,
increase the number of averaging measurements to ensure more accurate measurement.
Measurement target
The measured value may be incorrect if the shape or surface condition of the target varies
with individual targets. In this case, measure a known target and use the calibration
function to correct the error.
Handling
Do not wipe the unit with a wet cloth, benzene, or thinner. This may cause discoloration or
deformation of the housing. If the unit becomes dirty, wipe it off with a cloth moistened with
a mild detergent and then wipe with a soft dry cloth.
Effect of atmospheric motions
Slow atmospheric motions may affect the measurement and result in fluctuation of the
measured value.
In such a case, take the following countermeasures:
•Enclose the sensor head in an appropriate enclosure.
6

Precautions on wiring
Part of the input/output circuit of the LK-G5000 Series is internally common. Be careful that
no potential difference is generated between the internally common terminals due to the
potential difference between the cables/external devices. Such a potential difference may
cause a breakdown of the product or external devices.
Wiring example
LK-G5001V/LK-G5001 (NPN type)
The 24 VDC (-), COM OUT (COM for output), and COM IN (COM for input) terminals are
common through choke coils respectively. They are also common with COM OUT and
COM IN of the expansion connector through choke coils.
LK-G5001PV/LK-G5001P (PNP type)
The 24 VDC (-) and COM IN terminals are common through choke coils. They are also
common with COM IN of the expansion connector through choke coils.

Precautions on connection with a PC or other external device
In a positive ground environment, when the LK-Navigator 2 software is used by
connecting a PC through USB or LAN, or when RS-232C communication is used with a
PC, be careful of a short circuit created between the internal components of the PC and
the SG (GND) terminal of the LK-G5000.
The 24 VDC (-) terminal, SG (GND) of the USB port, SG (GND) and 24 VDC (-) of the RS-
232C connector, and SG (GND) of the Ethernet port are common through choke coils
respectively. Be careful that no potential difference is generated between these terminals
and the external device such as a PC or PLC. If any potential difference exists, isolate the
external device or the I/O terminals of the LK-G5000 Series except for those used for the
power supply, RS-232C, USB and LAN.
If the power supply terminal (24 VDC) is short-circuited through the internal component of the PC and
the SG (GND) terminal of the LK-G5000 Series, a product breakdown may occur. If this is the case,
isolate either the PC (1) or the LK-G5000 Series (2).
The internal wiring of a PC or PLC varies depending on the device. Refer to the instruction manual of

Mounting/Connecting the Units
Attaching the ND Filter (Option)
If the head is installed for specular reflection and the measurement target is a shiny mirror
or glass surface, the received light intensity may saturate. In such a case, by attaching the
ND filter (LK-F2/LK-F3) saturation can be avoided, thus enabling accurate measurements
to be taken.
Mounting the sensor head
Determine the distance between the sensor head and the measurement target, and
secure the head using screws through the two mounting holes.
It is recommended that you provide insulation when the LK-G5000 Series is used in a positive ground
environment.
Ambient temperature for the sensor head
When the sensor head is mounted onto a plastic object, limit the ambient temperature to 45C or lower.

1 Before Use
Mounting the controller
Mount the controller to the DIN rail, or secure it with screws.
Caution on the orientation of the controller
Mount the controller only in the orientation shown with a circle in the following figures. Do
not mount it upside down.
To secure the controller with the screws on
the bottom
Provide clearance of 50 mm or more above, 30
mm or more on each side, and 30 mm or more at
the rear of the controller for ventilation.
In addition, for ensuring the safety of the cable
connection work, provide 65 mm or more space in
front of the terminal panel of the controller.
To mount the controller to the DIN rail
Provide clearance of 30 mm or more between the
controllers, 50 mm or more above and 30 mm or
more below the controller.
CAUTION
•Do not block the ventilation holes on the top and
bottom of the controller. The heat may stay inside and
cause a malfunction.
•When the temperature inside the control panel exceeds the specified ambient temperature (50C when
one or less head expansion unit is connected, 40C when two or more head expansion units are
connected), decrease the temperature of the controller bottom to the specified ambient temperature or
lower by using forced air cooling or by providing more clearance around the controller.

Connecting the units
CAUTION
•Be sure to turn off the power of the controller before connecting/disconnecting the cables. Failure to
do so may cause product breakdown.
•Check the orientation of the connector before connecting it. Improper connection may break the
connector pins, resulting in product breakdown.
•Part of the input/output circuit of the LK-G5000 Series is internally common. Be careful that no
potential difference is generated between the internally common terminals due to the potential
difference between the cables/external devices.
Refer to "Precautions on wiring" (page 7) for details.
Connecting the sensor head
Connect the connector of the head-to-controller cable to the head connector 1 or 2 on the
terminal panel of the controller. Ensure that a clicking sound is heard which indicates a
secure connection. When disconnecting the cable, pull out the connector while holding
down the buttons on both sides. Up to two sensor heads can be connected to the
controller at the same time.
When the LK-HA100 head expansion units are used, up to 12 sensor heads can be connected.
•For each sensor head connection, use only one head-to-controller extension cable and limit the
total length to 30 m at maximum.
•You cannot connect the CB-AE to the CB-A30.
•You cannot connect two CB-A10E cables to the CB-A10.

Connecting the display panel
When using the separate type controller, connect the display panel cable between the
display panel connector of the controller and the display panel.
The LK-G5000 Series can also be operated without the display panel. Moreover, you can use the LK-
Navigator 2 software to operate the LK-G5000 Series from a PC or to display the measured value on a
PC.
Connecting the power supply
Connect the 24 VDC power supply to terminals 1 and 2 of the 12-pin terminal block.
CAUTION
Be sure to observe the following instructions. Otherwise, a connection failure may occur, causing a
malfunction in the LK-G5000.
•For the power supply cable, use lead wires with a nominal cross-section area of 0.8 mm2 to 1.3 mm2
(AWG17 to 18).
•The unsheathed wire length should be approx. 9 mm.
•Do not use soldering (preliminary soldering) to connect the wires.
•Insert the wires into the innermost position of the terminal block securely.
•Connect the wires to the terminal block directly, without using a crimp terminal, etc.
The CA-U3 or MS2 Series manufactured by KEYENCE is recommended for the 24 VDC power supply
unit.
Connection to the terminal block
The procedure to connect electrical wires to the terminal block are as follows:
1Remove the terminal block from the controller.
Loosen the two screws with a screwdriver and pull out
the terminal block.
2Use a screwdriver to push in part (a) and insert a
lead wire into part (b) as indicated.
3Remove the screwdriver once the wire is fully
inserted.
Pull each lead wire gently to confirm that it is properly
secured.

Setting the Tolerance Comparator Value
This section describes how to read the tolerance comparator display and how to set it.
The function of the tolerance comparator setting
You can set limit values (tolerance comparator values) used to decide whether the
measured value is within the allowable range. The measured values are classified into
three levels based on the limit: HI when the value exceeds the upper limit, LO when the
value is below the lower limit, and GO when the value is within the allowable range. The
result can be displayed or output.
When the comparator output form (page 3-63) is set to "Normal", the comparator output is
as follows.
•Refer to "Setting the output form of the tolerance comparator result (Comparator output form)" (page
3-63) for details of the comparator output form.
•The tolerance comparator result is output from the 12-pin terminal block and expansion connector
on the terminal panel of the controller. Refer to "Function of the I/O terminals" (page 4-2) for details
of the external output terminals.
Measurement stops during the setting.

Hysteresis
If the measurement value is fluctuating around the tolerance comparator value, the
comparator output may repeatedly turn on and off. By setting a hysteresis, an allowance
can be made between the detected value and the return value of the tolerance
comparator, preventing such a phenomenon. The diagram below shows the comparator
output when the comparator output form is set to Normal. Hysteresis is disabled by
default.
Measurement stops during the setting.

Instantaneous Zero Setting (Auto-Zero)
This section describes the auto-zero function which is used for reference zero point
compensation.
The auto-zero function can be used to set a reference point at "0", for example, when the
target is changed. You can instantaneously reset the currently displayed value to "0" by
pressing the [ZERO] key or other operation. An increase or decrease in the displayed
value relative to the zero point (reference point) can be displayed with the "+" or "-".
The auto-zero cannot be set during the comparator standby status ("++++++" is displayed), over
range status, or alarm status. (Canceling auto-zero is possible.)
•The auto-zero value is stored for each program No. and OUT No.
•The auto-zero value is retained even if the power is turned off.
•When the measurement mode is other than Normal, the system enters the comparator standby
status ("------") after auto-zero is set.
•Master target adjustment using the offset function (auto-offset function)
When the offset value has been set to the size of a master target, setting the auto-zero while the
master target is being measured will set the displayed value to the size of the master target (offset
value) (page 3-47).
•The auto-zero is applied to the measured value after it is processed with the measurement mode
operation (page 3-37).

When ZERO (Terminal 8) and COM for input (Terminal 1) of the expansion connector are
turned ON while DEC_IN (Terminal 16) and COM for input (Terminal 12) of the expansion
connector are turned ON, the auto-zero is set for the OUT selected with the B_IN terminal.
Limit the turn-on time for the terminals to less than two seconds.
•NPN type : OFF when opened/ON when short-circuited
•PNP type : OFF when opened/ON when voltage is applied
•When the synchronization is not set, the auto-zero is set to OUT01 when the ZERO1 terminal is
turned ON.
•The measurement value at the instant when the terminal is turned on is set to "0.0000".
•If the ZERO1 or ZERO2 terminal is turned on for two seconds or more, the auto-zero is canceled.
Auto-zero input using the RS-232C interface
The auto-zero function can be set or canceled with the command sent from the external

Specifying the action when measurement becomes impossible (Alarm handling)
Measurement becomes impossible when the result is out of the measurement range or
when the received light intensity is excessive/insufficient. The alarm handling function is
used to specify how to process data in these situations.
Setting Function
Process count
Specifies the number of sampling times for which the last normal value is held after
measurement becomes impossible.
•Setting range: 0 to 9999
•If measurement is still impossible after the number of sampling times exceeds this value,
the measured value is
displayed as "-FFFFFF".
•Holding is released when the system recovers to the measuring status within the specified
process count.
•When the process count is set to "9999", the normal value is continuously held until
measurement becomes possible.
•If the alarm occurs immediately after the power is turned on and there is no measured
value, "-------" is held.
Recovery
count
After measurement becomes impossible and an alarm is issued (-FFFFFF is displayed), if the
number of valid measured values reaches the specified recovery count, the system recovers
from the alarm.
•Setting range: 0 to 9999
•If another alarm is issued before the number of valid measured values reaches the
specified recovery count, the count is reset.
Level Sets the threshold level of the received light status below which a peak is judged as invalid.
•Setting range: 0 to 9
•"0" is the least sensitive to the alarm and "9" is the most sensitive.

Automatically adjusting the ABLE adjustment range according to the target (ABLE calibration)
The ABLE calibration function optimizes the adjustment range for ABLE based on the
actual measurement of the target. This function is useful when the reflectance of the target
changes greatly in a short cycle.
•The ABLE calibration must be conducted after the completion of the OUT settings and Common
settings.
•Note that the ABLE calibration fails in the following cases:
- The target sensor head for the ABLE calibration is not assigned to any OUT.
- The target sensor head for the ABLE calibration is set to "AB-ON" but assigned to
group "C" in the mutual interference prevention setting.
- The input to the REMOTE terminal or LASER CTRL1/LASER CTRL2 terminal for the
target sensor head for the ABLE calibration is turned off.
Operation flow of the ABLE calibration
1Measure an actual target as shown in the figure.
2Start the ABLE calibration (page 3-14).
The data collection starts.
3Move the target slowly.
4Stop the ABLE calibration.
The data collection finishes and the optimum range for ABLE is set.
•When the ABLE calibration is performed, the ABLE setting for function symbol A (page 3-6) is set to
MANUAL, and the upper and lower limits of control are set to the adjusted values.
•By slowly moving the target, you can optimize the adjustment range for ABLE. Such optimization of
the adjustment range improves the response when the reflectance of the target changes greatly in a
short cycle.

Setting the mounting mode according to the sensor head mounting method (Mounting mode)
The LK-G5000 Series measures the displacement of a target by measuring the laser beam
reflected from the surface of the target. When the target surface is flat, such as a mirror or
glass plate, the specular reflection component of the reflected light increases. In such a
case, use the specular reflection mounting so that the sensor head receives the specular
reflection light properly.
The following two types of mounting modes are available.

Measurement is performed within the period of time specified with the external
synchronous input (sampling period), and the displayed/output value is retained. The
sampling period differs between the Trigger 1 and Trigger 2 settings.
•When Trigger 1 is selected (page 3-45), the sampling period is the period between the
instant when the synchronous input turns on and the instant when the next synchronous
input turns on. When the synchronous input turns on, the measured value for the
preceding sampling period is output.
The RESET operation is not performed when the synchronous input is turned on.
•When Trigger 2 is selected (page 3-45), the sampling period is the period when the
synchronous input is turned off. When the synchronous input turns on, the measured
value for the preceding sampling period is output.
The RESET operation for the internal measured value is performed when the
synchronous input turns off.
•In the following cases, the comparator standby status (the display shows "______")
continues until the first measured value is determined:
When the power is turned on, when a setting is changed, when a program number is
changed, when RESET is input, or when auto-zero is input.
•The comparator output is provided according to the measured value.
•The ON state of each output indicates that the NPN or PNP open-collector output is

: A sensor head set to the corresponding measurement mode can be connected
X : When a sensor head set to the corresponding measurement mode is not used
- : Setting impossible
The values in the parentheses are the number of OUT which can be used for the calculation of ADD,
SUB, P-P, MAX, MIN, and AVE among OUT.
•The number of OUT which can be set to the velocity/acceleration measurement varies depending
on the sampling cycle as follows: 2.55 μs: 1, 5 μs: 2, 10 μs: 4, and 20 μs or longer: 12. (When the

Setting the mutual interference prevention function (Mutual interference prevention)
When more than one sensor head are connected and mounted in close proximity, they
may receive the light emitted from the other sensor head, resulting in a measurement error.
The mutual interference prevention function assigns the sensor heads to three groups at
maximum, A to C, to allow these groups to emit light alternately. This prevents interference
with the sensor heads in the other group.
The following procedure enables the mutual interference prevention function for groups A
and B as an example.

Storing the measured values in the memory (Data storage function)
The LK-G5000 Series can store up to 1,200,000 measured values (1,200,000 is a total and
the available number for each Out Channel depends on the number of Out Channels to
store data) in the internal memory using the external synchronous input or in every storage
cycle. The stored data can be read and checked by using the RS-232C interface or the
LK-Navigator 2 software.
The settings of the function numbers and sub-functions are as follows.
•The data to be stored is the measured value of the Out Channel after it is processed with the
specified measurement mode and other operations (page 3-2).
•The "storage cycle" is specified as the multiple of the sampling cycle. When the storage cycle is set
to "Synchronization input", the data is stored in synchronization with the TIMING1 input, the LK-
Navigator 2 operation, or the simultaneous timing button of the LK-HD1001.
•The storing operation stops when the number of stored data exceeds the specified number.
•The storage time can be calculated as "Sampling cycle x Storage cycle x Number of data".
•Even when the refresh cycle, which is determined with the number of averaging measurements, is
longer than the sampling cycle, the data is stored based on the sampling cycle. In this case, the
same measured value is stored until the measured value is updated.
•Even if "auto-zero" or "RESET" is input during data storage operation, the storage continues without
clearing the stored data.
•When this function is started and stopped repeatedly, the new data is stored after the old data.
•From the display panel (HD500), the number of stored data can be set to only 999,999 at maximum.

•The binary data should be imported in synchronization with the strobe signal being
turned on.
•The minimum input time (T1), input response time (T2) and refresh cycle (T5) vary
depending on the settings.
•The STROBE time (T3) can be changed.
•When the sampling cycle (T6) is 20 μs or less, the STROBE output’s T6 is fixed to 20 μs.
•In any of the measurement modes, when the BINARY output is switched while strobe

External synchronization for data storage, RS-232C automatic transmission
The STROBE output type depends on the synchronization setting.
•When the measurement mode for synchronized OUT is not sample hold (Trigger 2):
After TIMING1 is input and the input response time (T2) has elapsed, data storage (RS-
232C automatic transmission) is performed.
•When the sample hold (Trigger 2) is selected as the measurement mode for some of the
synchronized OUTs:
– The STROBE output method is decided by the smallest OUT No. among the OUTs
selected for synchronization control. (For example, when all of OUT1 to OUT12 are
set for synchronization control and comparator outputs 8 to 12 are selected with B_IN,
the smallest OUT No. is "OUT1", regardless of the B_IN input.)
– If comparator output is selected with B_IN and synchronization control is not set,
STROBE output is disabled.

measurement mode for some of the synchronized OUTs.
•Even when the next data is determined during the automatic transmission, the data is

Refresh timing during high-speed sampling
•The operations when the sampling cycle is shorter than the I/O refresh cycle are as
follows:
•If all comparator results are GO in one refresh cycle, GO turns on at the next refresh.
•If at least one comparator result is HI (LO) in one refresh cycle, HI (LO) turns on at the
next refresh.
•If both HI and LO exist in one refresh cycle, both HI and LO turn on at the next refresh.
•Binary output is updated to the latest value in every refresh cycle.
•The I/O refresh cycle depends on the sampling cycle and mutual interference
prevention setting.

•The sampling cycle can be changed (15).
•When the sampling cycle is changed, the measurement response time, measurement
averaging time, RESET time, and refresh cycle also change accordingly.
•When the mutual interference prevention function is used, the sampling cycle T6 is
calculated as T6 x 2 (for AB_ON) or T6 x 3 (for ABC_ON).
•When "Velocity" is selected for the measurement type, T4 is calculated as T4 + T6; when
"Acceleration" is selected, T4 is calculated as T4 + 2 x T6.

Outline of the command format
The LK-G5000 Series controls operation based on the incoming command received from
the external device, and then sends back the response command to the external device.
is used to delimit each piece of data in the incoming/response command format.
When creating a control program, build it so that you confirm the reception of the response command
from the LK-G5000 Series before sending the next command.
Both upper-case and lower-case characters can be used in the command.
The presence or absence of the section enclosed with brackets ([ ]) in the command format depends
on the condition.

Measured Value Output through External
Synchronization
This section describes how to output the measured value through the RS-232C interface
in synchronization with the measurement triggered by the signal from the input terminal
(TIMING1 input). Since no incoming command is used, this method is useful when you
only need to import the measured value or when the LK-G5000 Series is connected to a
device that cannot send commands such as a data logger. The OUT terminals which
output the measured values with this method are the synchronized OUT only.
Commands for measured value output and for changing settings can be used even when the
measured values are being output through the external synchronization (when the external trigger
input is not OFF).
Do not attempt to determine the next measured value while the current measured value is being output
through the RS-232C interface. That next measured value will not be output.
Environment settings parameters
Set the environment settings as follows (page 3-72).
Output type
The measured value to be output is the value determined by the external synchronization
(TIMING1 input).
The output is set as follows depending on the automatic transmission setting.
Item Setting value Remark
Baud rate 9600/19200/38400/57600/115200 bps Set the appropriate parameter
according to the external device to be
connected.
Parity None/even/odd

number is changed, the auto-zero operation is completed, and the RESET input is provided.
•If the RS-232C, USB, or LAN communication is used in the measuring mode, the response speed
slows down.
•The RS-232C, USB, and LAN interfaces cannot be used simultaneously.
•When the LK-Navigator 2 setup support software is used, the change to the communication mode
and return to the measuring mode are automatically controlled by the software.
•When the RS-232C communication is used with the LK-Navigator 2, the refresh rate becomes slow
compared with the rate using the USB or LAN communication.

Response delay time
Measurement response time
This is the period of time until the LK-G5000 Series recognizes the change in the target
and outputs the signal. This is calculated by the following formula.
•For details about the sampling cycle (T6) and reset time (T4), refer to "Timing details"
(page 4-26).
•When the mutual interference prevention function is used, the sampling cycle T6 is
calculated as T6 x 2 (for AB_ON) or T6 x 3 (for ABC_ON).
•When "Velocity" is selected for the measurement type, T4 is calculated as T4 + T6; when
"Acceleration" is selected, T4 is calculated as T4 + 2 x T6.
Power ON reset time
This is the period of time until measurement starts after the LK-G5000 Series is turned on.
•Power ON reset time when only the controller is used: Approx. 7 seconds
•When 10 head expansion units are connected to the controller: Approx. 17 seconds
