[. . . ] Z250-E1-02 Smart Sensor ZG Series 2D Profile Measuring Sensors User`s Manual Introduction Thank you for purchasing the ZG series. This manual provides information regarding functions, performance and operating methods that are required for using the ZG. When using the ZG, be sure to observe the following: · The ZG 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. [. . . ] The measurement target is actually measured and the correction value is registered. The angle of inclination () is calculated from the width and the difference in height of two locations, and registered. The profile is corrected by this angle of inclination at all times. Important The registered slope correction is cleared when the following settings are changed: · CCD mode · Sensor installation 100 System Settings ZG User's Manual FUN mode-[SYSTEM]-[SENSOR SET]-[CORECT]-[INCLINATION] SYS/INC. 1 Set the measurement target in place, and select [TEACH]. 1TEACH SYS/INC.

Setting correction ON/OFF Set Sensor inclination correction ON/OFF. FUN mode-[SYSTEM]-[SENSOR SET]-[CORECT]-[CORECT] Setting value OFF ON Description Sensor inclination correction is not performed. (default value) Sensor inclination correction is performed. 102 System Settings ZG User's Manual Setting the CCD Mode Set the resolution of the Sensor's CCD. The profile can be set to high-resolution or the response time can be speeded up by changing the CCD mode. CCD Mode p. 156 Important When the CCD mode is changed, the bank data is initialized. So, be sure to start with teaching again. FUN mode-[SYSTEM]-[CCD MODE] Setting value NORMAL (standard mode) HI-RESO (high-resolution mode) HI-SPEED (high-speed mode) Description Standard measurement is performed. (default value) Measurement is performed at a resolution of about four times that of the standard mode. Measurement is performed with the number of pixels halved in the height direction. This mode is suited to measurement of shapes in fast line speed processes as the measurement cycle is fast. Note, however, that the possible measurement distance becomes roughly 1/2 of the rated distance. ZG User's Manual System Settings 103 3 FUNCTION SETTINGS Setting the RS-232C Communication Specifications Set the communication specifications for the Controller matched to the communication specifications of external devices. FUN mode-[SYSTEM]-[RS-232C] Setting value LENGTH PARITY STOP (stop bit) BAUDRATE DELIMITER Description 8BIT, 7BIT (default value: 8 BIT) NONE, ODD, EVEN (default value: NONE) 1BIT, 2BIT (default value: 1BIT) 9600, 19200, 38400, 57600, 115200 (default value:38400) CR, LF, CR+LF (default: CR) Setting the Node No. This node No. Not only the ZG series but also two or more devices can be connected to the PLC. assigned to devices connected to a PLC in this instance is referred to as a node No. FUN mode-[SYSTEM]-[NODE] Setting value 0 to 16 Description This node No. (default value: 0) 104 System Settings ZG User's Manual Setting the Sensor Data Loading Method Various data is saved in the Sensor. Set at which timing this information is to be loaded to the Controller. FUN mode-[SYSTEM]-[Sensor DATA] Setting value Sensor CONTROLLER Description Reads the data currently saved on the Sensor each time that the Controller is started up. (default value) Data is not read from the Sensor when the Controller is started up if the same Sensor at the previous startup is connected. 3 Important When the combination of Controller and Sensor is fixed, selecting "CONTROLLER" sometimes results in the Controller starting up more stably depending on the operating environment. FUNCTION SETTINGS Setting the Number of Digits Past the Decimal Point Set the number of display digits past the decimal point that are displayed in the measurement result on the monitor. When five or less digits are set, the digits are disabled from the rightmost digit first. FUN mode-[SYSTEM]-[DIGIT] Setting value 5, 4, 3, 2, 1 Description Sets the number of display digits past the decimal point. (default value: 3) Note The number of digits past the decimal point in serial output follows the setting made here. ZG User's Manual System Settings 105 Setting/Changing the ECO Display Darkens the LCD screen to suppress current consumption when control keys or selection switches are not operated for three minutes or longer. FUN mode-[SYSTEM]-[ECO MODE] Setting value ON OFF Description The ECO mode setting is enabled. [. . . ] The Controller will break down and can no longer start up normally. 198 Updating the Firmware ZG User's Manual 9 Check the message and click the [OK] button. The firmware update will start. During the update, the progress status will be displayed. Wait until a message informing completion of the update is displayed. (The update takes several minutes to complete). Important · During a firmware update, an error may occur on the Controller. [. . . ]
