2 Setup using LK-Navigator 2 (LK-H2) This section will cover basic setup using LK-Navigator 2. What is LK-Navigator 2? LK-Navigator 2 is a software package that can be used to set up the LK-G5000 and acquire measurement values. Launching LK-Navigator 2 Connect the sensor head to the controller and turn on the power. Prepare the PC that has had LK-Navigator (LK-H2) installed on it and then connect the controller to the PC via USB cable. Double click the LK-Navigator 2 icon to launch LK-Navigator 2.
Sending settings Once the button for “Send settings to controller” is clicked, the settings that have been created in LK-Navigator 2 will be applied to the controller. Receiving settings Once the button for “Receive settings from controller” is clicked, the controller settings will be downloaded to LK-Navigator 2. This is useful when checking the settings that are currently being used. Displaying measurement values Using LK-Navigator 2, it is possible to check the current measurement values.
3 Sensor head-related settings This section covers basic head level processing settings. Head settings This section controls head level target optimisation processes. This makes it possible to select measurement modes that are optimised for specific target surface conditions and materials, and allows for corrections to compensate for sensor head mounting. Measurement mode Selects settings that have been optimised for various target surfaces.
Transparent object 2 mode Used when measuring transparent object target that have multiple surfaces that differ in reflectivity such as when measuring metal-deposited glass. Semi-opaque object mode Used when measuring diffuse targets with strong surface luster. Mounting mode Selects settings in response to the mounting method for the sensor head. “Diffuse reflection” As listed in P.2 of this guide, this setting is used when the sensor head is mounted perpendicular to the target.
4 OUT settings These settings related to measurement value processing. OUT settings With the LK-G5000, measurement values can be calculated and displayed for each OUT. At default, the number of used OUTs is 2, and up to 12 can be set. The number of used OUTs can be set in the environment settings. *Once the “No. of used OUT” is changed, all programs will be initialised. The number of used OUTs must be the first thing to be set.
Measurement/Tolerance-Measurement type Selects which of the following targets will be measured in “Measurement type”. Displacement/Speed/Acceleration Measurement/Tolerance-Filter Settings related to measurement value processing are performed in Filter. By setting the moving average, it is possible to stabilise measurement values. The measurement values are set with a moving average in the range of 1 to 262144 times. When an average of 4x has been set, the following process will occur.
5 Measurement setup examples This section provides application setup examples. Eccentricity/Vibration Measurement Setting Methods Setting methods when performing eccentricity/vibration measurements are as follows. Preparation and Overview Required Components LK-G5000 Series controller LK-G5000 Series sensor head LK-G5000 Series head cable LK-Navigator 2 configuration software 24 V power source No.
Settings and Procedures The following settings should be used as a default. 1. Measurement mode and average frequency settings (1) Change the measurement mode for OUT1 to “PEAK-TO-PEAK HOLD” and change the average frequency to 1 time or as needed. (2) In “General” under “Common Settings”, set the “Sampling cycle” to 20 μs or as needed. (3) Click “Send settings to controller”. (Pg. 5 of this guide). 2. Measuring the amount of eccentricity and vibration (1) Click “View Measurement Value”.
Thickness Measurement Setting Methods When two sensor heads are connected to measure thickness between the two sensor heads, the setting method is as follows. With measurement between two sensor heads, it is possible to minimise the influence of vertical vibration. Preparation and Overview Required Components LK-G5000 Series controller LK-G5000 Series sensor head LK-G5000 Series head cable LK-Navigator 2 configuration software 24 V power source No. of units 1 2 2 1 1 1.
Settings and Procedures The following settings should be used as a default. 1. Setting the number of used OUTs (1) Click “Environment Setting”. (2) Set the number of used OUTs according to the number of thickness areas that will be measured. Measurement area X 3 = Number of used OUTs Ex.) If one thickness area is measured, then the number of OUTs that will be used is 3 (3) Click [OK]. 1. Changing OUT settings (1) Click the “OUT settings” tab. (2) Configure each of the following settings.
3. Scaling settings This will explain the individual setting methods for the following two patterns. A: Calibrating with 2 master targets that have different dimensions B: Calibrating with 1 master workpiece * When measuring workpieces that have different thicknesses, accurate calibration can be performed with method A. A: Calibrating with 2 master workpieces that have different dimensions Ex.) Setting scaling for OUT3 with 1 mm and 1.
Setting methods for measuring the thickness of transparent objects The setting methods that are used when measuring the thickness of transparent objects with the LK-G5000 are as follows. With the LK-G5000, position data for the top and bottom surface are obtained as the detection surface, so it is possible to measure the thickness of transparent objects from one side.
2. For the calculation method for OUT1, set the measurement target to “[1st peak] – [2nd peak]”. Displaying received light waveforms Received light waveform when measuring transparent glass Sensor head Light-receiving element (CMOS) Bottom surface reflected light Light-receiving lens Top surface reflected light Top surface (1st peak) Transparent glass Waveform for received light from the top surface Waveform for received light from the bottom surface Bottom surface (2nd peak) 3.
Data storage function setting methods If the data storage function is used, it will be possible to save up to 1.2 million points of LK-G measurement data to the controller. If the LK-Navigator 2 is used, this measurement data can be checked on a PC and saved as a CSV file as well. Overview Up to 1.2 million individual measurement values for OUT1 through OUT12 can be accumulated to the internal memory for each external timing input or set storage cycle.
Settings and Procedures 1. Data storage function settings Controls the settings for the selected OUT, storage cycle, and amount of data stored. ❶ (1) Click “Data Storage”. (2) Click “Data Storage Setting” in the window that has appeared. * Once each setting has been configured, click “Send settings to controller”. 2. Selected OUT settings Check the selected OUTs that you wish to store. 3. Storage cycle settings The storage cycle is the cycle at which measurement data is stored in the internal memory.
4. Setting the amount of data stored The amount of data stored equals the number of data points that you wish to store. The storage time is equal to the amount of data stored x the storage cycle. * Once data storage settings have been completed, click “Send settings to controller”. For example, when setting the amount of data stored to 10,000 points and the storage cycle to 200 μs, the storage time will equal 2 seconds (= 10,000 points x 200 μs).
6 FAQ's Common Questions Q: Where can I find more details on the RS-232C commands for the LK-G5000 controller? A: The commands are described completely in chapter 5 of the user’s manual. All of the operations described in the user's manual can be performed using a combination of direct RS-232C commands. Q: What parts do I need to connect LK-G5000 to 9-Pin RS-232C port? A: While it is possible to crimp a custom cable, Keyence recommends the following components.
Connecting a PC/PLC link unit The connection requires the OP-96368 dedicated cable (2.5 m straight cable) and either the OP-26401 (D-sub 9-pin) or OP-96369 (D-sub 25-pin) conversion adapter. * Also refer to user's manual for the PC or PLC link unit before starting connection.
