Page 16: Node Address: Node Id
LDT10 HMI interface is a MODBUS Master device, the networked actuators are Slave nodes, so they must be provided with an univocal address. Lika devices support the UNICAST mode, so the Master node issues a MODBUS request to an individual Slave. -
Page 17: Data Transmission Rate: Baud Rate And Parity Bit
LDT10 WARNING In the Network setup page if you match a node with a wrong position (for instance you match the Actuator 2 position with an actuator having an address different from “2”), then the communication cannot be established and the COMMUNICATION ERROR following message will appear on the display. -

LDT10 HMI interface 5.1 Preliminary information Except for the first time the panel is started (for this case please refer to the “ 5.2 Starting the interface for the first time” section here below), at power-on the Home page appears on the display. From the Home page you can enter the full set of pages of the interface, provided that you comply with the protection level L required by the page. -
Page 19: Starting The Interface For The First Time
LDT10 5.2 Starting the interface for the first time When you start the interface for the first time, the system displays the Network setup page. In normal work condition this page can be accessed only by Level 2 – Administrator users while Level 0 - User and Level 1 – manager users (see the ”5.3 Safety levels”... - Page 20 LDT10 The access to the functions of the basic level 0 is free and does not require any password. While the access to the functions of the level 1 and the level 2 requires a password to be entered. Passwords cannot be modified. To enter a password, you must first access the Network page (see on page 25) and then press the key in the menu at the top of the page.

Page 21: Level 0 - User
LDT10 5.3.1. Level 0 - User It is the first security level and allows for a basic use of the interface. It does not require a password and is mainly aimed at the users that are involved in the production process. In this level the user is allowed to display most of the pages and to launch the recipes in order to start a production. -
Page 22: Level 2 - Administrator
LDT10 WARNING When you start the interface for the first time, as it is compulsorily necessary to match one actuator at least with the interface, the system allows also the Level 0 and Level 1 users to enter the Network setup page and match the available devices with the node positions. -

Page 32: Backlash Direction
LDT10 EXAMPLE Let's suppose that the actuator is installed on a 5-mm pitch worm screw. If you Pulse per revolution Decimals = 500 and = 2, at each rotation of the screw the system performs a 5-mm pitch with a resolution of one hundredth of a millimetre. - Page 33 LDT10 Backlash, sometimes called lash or play, is clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence", and is a mechanical form of deadband.
