Preliminar information
This guide is designed to describe the technical characteristics, installation and use of the LDT10 HMI
touch panel for Lika's DRIVECOD intelligent rotar actuators.
LDT10 is engineered to interface, set up and operate the whole series of RD rotary actuators with RS-485
MODBUS interface. It is intended to connect one single actuator (point-to-point connection), several
actuators in the network (up to 8 actuators) and even different actuator models in the same network
(RD1xA, RD4, RD5x and RD6 actuators can be installed and operate together).
The interface allows:
•to create a network of devices and configure the networked actuators;
•to collect data on the specific production (i.e. the work cycle of each actuator, its travel, …) and
save in recipes the information on each process;
•to manage the saved recipes and launch the program in order to activate the automatic change-
over operation and start the new production.
LDT10 is specifically engineered to make change-over operations faster and easier, cut set-up time and
reduce downtime, especially when small-batches, one-off items and just-in-time productions need
frequent and costly format adjustments. The automated multi-axis systems such as in the plastics
industry, mold changers, mobile stops, the packaging lines and the woodworking machines are a typical
example.
Please note that the present manual implies a perfect knowledge of the user's guide of the RD rotary
actuators it has to be connected to. Please read carefully the specific documentation before installing,
connecting and operating the actuators. Refer to the manuals describing the MODBUS interface models
(MAN RDx MB). Please download the complete technical documentation of the RD rotary actuators at
www.lika.biz > ROTARY ACTUATORS > ROTARY ACTUATORS / POSITIONING UNITS (DRIVECOD).
For detailed technical specifications please consult the product datasheet.
To make it easier to read the text, this guide can be divided into two main sections.
In the first section general information concerning the safety, the mechanical installation and the
electrical connection as well as tips for setting up and running properly and efficiently the touch panel
are provided.
In the second section, entitled HMI interface, both general and specific information is given on the
interface. In this section the interface features and the implemented functions are fully described.

MAN LDT10 E 1.2 Electrical connections 15 of 44

LDT10
4.3 Node address: Node ID
The MODBUS Serial Line protocol is a Master – Slaves protocol. One only Master
(at the same time) is connected to the bus and one or several Slave nodes are
also connected to the same serial bus. A MODBUS communication is always
initiated by the Master. The Slave nodes will never transmit data without
receiving a request from the Master node. The Slave nodes will never
communicate with each other. The Master node initiates only one MODBUS
transaction at the same time.
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.
Before networking a device, the univocal address must be set. The node
address is set via hardware in each device b using the dip switches
located inside the enclosure. LDT10 interface allows to network up to 8
actuators; their address has to be in the range from 1 to 8. For more information
on setting the node address please refer to the specific documentation
regarding the MODBUS interface models.
In the Network setup page it is possible to match the networked actuators with
the interface; as stated, their address has to be between 1 and 8. The device
having the physical address 1 must be compulsorily matched with the Actuator
1 position; the device having the physical address 2 must be compulsorily
matched with the Actuator 2 position; and so on. For more information refer
also to the “5.4 Network setup page” section on page 23.
MAN LDT10 E 1.2 Electrical connections 16 of 44

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
following COMMUNICATION ERROR message will appear on the display.
WARNING
If the rotary actuator is either the first or the last device in the network (i.e. it is
installed at the ends of the network), the provided RT bus termination resistor
has to be activated as line termination. Use the RT switch located inside the
actuator's enclosure to activate or deactivate the bus termination. For detailed
information please refer to the specific documentation of the actuator.
4.4 Data transmission rate: Baud rate and parit bit
HMI LDT10 interface allows 9600 bits/s data transmission rate with “Even” parity
bit. Different baud rates are not supported.
WARNING
DRIVECOD rotary actuators are fitted with a hardware switch designed to set
the baud rate and the parity bit. It is located inside the actuator's enclosure. As
their default setting is “1000”, that is: baud rate = 9600 bits/s, parity bit = Even,
no further setting is usually required. If you are going to integrate a previously
networked actuator, please check that the baud rate and the parity bit switch is
set to “1000”. For detailed information please refer to the documentation of the
specific actuator.

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” section on page 19) are not allowed. Yet in this first phase as
it is compulsorily necessary to match one actuator at least with the interface,
the system enables also the Level 0 users and the Level 1 users to enter the page
and match the connected devices with the node positions. Once you install one
actuator in the page, after pressing the key and exiting the page, any
further access will be allowed to the Level 2 – Administrator users only.
Otherwise, if no configuration is made, the Network setup page will be
displayed again at next power-on.
For complete information on the Network setup page please refer to the “5.4
Network setup page” section on page 23.
5.3 Safet levels
The interface provides three safety levels. In some cases they restrict the usage
permissions or prevent the users from entering the pages or accessing some
functions available in the pages.
The three levels are:
•L0 level 0 = User level;
•L1 level 1 = Manager level;
•L2 level 2 = Administrator level.
MAN LDT10 E 1.2 HMI interface 19 of 44

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. As soon as
you press the key, the following on-screen numeric keypad will appear:
•Enter the Level 1 – Manager password (“1122”, see the “5.3.2 Level 1 -
Manager” section on page 21) to gain access to the functions of the
level 1;
•enter the Level 2 – Administrator password (“2233”, see the “5.3.3 Level
2 - Administrator” section on page 22) to gain access to the functions
allowed for the level 2.
Confirm by pressing the ENT key. To enter back the basic User level press the
key again.
The protection level that is currently enabled is shown in the message in the
menu at the top of the page:
•no message: level 0 - User;
•“Manager level enabled”: level 1 - Manager enabled;
•“Admin level enabled”: level 2 - Administrator enabled.
NOTE
Should you type a wrong digit while entering the password, press the ESC key in
the keypad to exit the digit entry mode, then repeat the operation.
