[. . . ] Z302-E1-0 FQ ZX-T Series Vision Sensor USERS MANUAL Introduction Thank you for purchasing the FQ. This manual provides information regarding functions, performance and operating methods that are required for using the FQ. When using the FQ, be sure to observe the following: · The FQ must be operated by personnel knowledgeable in electrical engineering. · To ensure correct use, please read this manual thoroughly to deepen your understanding of the product. [. . . ] Test measurements can be performed for through images (default) or saved images. Performing Test Measurements with Samples [Test] - [Continuous test] 1 2 3 Press [Graphics+Details]. When you finish checking the results, press [Back]. Note The same five types of displays are available for the [Continuous test] on the [Test] Tab Page, i. e. , [Graphic], [Graphics + Details], [All results/region], [Trend monitor], and [Histogram]. Press the [Back] Button to access the menu to change the display. Changing the Run Mode display: p. 84 Performing Test Measurements with Saved Images (Re-measuring) This Sensor can save measured images in the Sensor's built-in memory or on an SD card. This function is useful for adjusting the judgement parameters when objects are not available. [Test] - [Continuous test] - (Any display) 1 Press - . 74 Performing Test Measurements FQ User's Manual 2 Select [Log] or [File]. Images in the Sensor's built-in memory: Press Log. Images on the SD card: Press File. 3 The display switches to the saved image and measurements are taken again. Saving images: p. 110 5 Testing and Saving Settings 75 Performing Test Measurements FQ User's Manual 5-2 Shortening the Measurement Takt Time Checking the Measurement Takt Time The measurement time of this Sensor can be checked from the Setup or Run Mode display. Measurement time The measurement time is the time taken from when a trigger is input until when all measurement processes are executed. During the measurement time, this Sensor will not accept the next trigger. This means that the measurement time is the basic measurement takt time. Inputting a trigger Measurement time = Measurement takt time Image input Measurement File logging Display Increasing Image Input Speed With the partial input function, it is possible to input only images that are in the region that is necessary for measurements. The image measurement region becomes smaller and thus the image input time is shortened. [Image] - [Camera setup] 1 2 3 4 Press [ play. ] ­ [Partial input] on the right side of the dis- Change the input size. Press [Back]. Important If you use partial input, perform teaching again. 76 Shortening the Measurement Takt Time FQ User's Manual 5-3 Adjusting the Judgement Parameters Adjusting Judgement Parameters While Looking at Measurement Results If correct judgements are not possible, you can move directly from the Setup Mode display to the judgement parameters display to make adjustments. [Test] ­ [Continuous test] ­ (Either display) 1 2 Press [ ] - [Adjust judgement] on the right of the display. Adjust the judgement parameters. Upper limit Lower limit Setting Up the Best Judgement Parameters Automatically The judgement parameters of the selected inspection items can be automatically adjusted by using actual workpieces which are considered as good and faulty products. 5 Testing and Saving Settings [Test] - [Continuous test] 1 Move to the inspection item for which you want to automatically adjust the judgement parameters and press [ ] ­ [Adjust judgement] on the right side of the display. Press [ ] ­ [Auto adjustment]. 2 3 Display a sample image of a good object and press [OK Teach]. Display a sample image of a bad object and press [NG Teach]. 4 5 6 Repeat these steps for at least two samples each. Press [OK]. FQ User's Manual Adjusting the Judgement Parameters 77 Note You can select one of the following three patterns as the judgement method. [ ] - [Select the method. ] on the right side of the display 1) Threshold (minimum): The lower limit of the variations between OK object is used as the judgement condition. 2) Threshold (average): The median value between the OK object variations and NG object variations is used as the judgement condition. 3) Threshold (maximum): The upper limit of the variations between NG object is used as the judgement condition. Number of registered samples Press [NG Teach] to register. Press [OK Teach] to register. Measurement value 3) 2) 1) 78 Adjusting the Judgement Parameters FQ User's Manual 5-4 Checking a List of All Inspection Item Results Individual judgement results for all inspection items can be checked in a list. The individual inspection items can be selected to change the judgement parameters. [Test] - [Continuous test] 1 Press [All results/region] to display the list. Note Judgement parameters can also be changed from this display. Select an inspection item and press [ ] ­ [Adjust judgement]. 5 Testing and Saving Settings 79 Checking a List of All Inspection Item Results FQ User's Manual 5-5 Saving Data to the Sensor Until you have saved your settings explicitly to the memory in the FQ Vision Sensor, the settings are only stored temporarily. The FQ Vision Sensor will remind you to do so with a message if you switch from Setup Mode to Run Mode. You can use this feature to keep the previous settings and discard the new settings if desired, but keep in mind that all settings that are not saved explicitly are replaced by the settings that are stored in the memory of the FQ Vision Sensor the next time you turn ON the FQ Vision Sensor. Important Do not turn the power supply OFF while data is being saved. The data that is being saved may become corrupted. [Test] 1 2 Press [Save data]. Press [Yes]. Note · Scene data and system data can be saved in this way. Scene data and system data details: p. [. . . ] Class 1M laser products that failed condition 1 of table10 of the standard.
