Lika Electronic's RD7 rotary actuator combines the benefits of automatic changeovers and adjustments with the advantages of wireless technology. It makes production processes more flexible and efficient, shortens changeover times, cuts costs, reduces downtime and minimises the risk of errors and material waste. It easily replaces manual handwheels and position indicators, for example when modernising existing equipment. It also reduces installation problems by eliminating signal wiring and makes it easier to programme and control the actuator network remotely. An alternative RS-485 wired communication (Modbus RTU compliant, wired and plugged output options) is available on request.
The RD7 rotary actuator integrates the motor, encoder, controller and antenna in a single package that is very compact and takes up less space than conventional manual handwheels and position indicators. The robust housing is dustproof and waterproof to IP65. The through hollow shaft has a diameter of up to 20 mm (0.787 inch). Adapter flanges, reduction sleeves and high torque adapters can be supplied to meet individual installation requirements. The RD7 is also equipped with a diagnostic LED and some buttons for setup and jog functions, and can also be supplied with a 7-segment display.
Wireless connection benefits
The drive eliminates the need for communication cables, reducing installation costs. Using a single 2.4 GHz wireless transceiver with DIN rail mounting compatibility, up to 32 units can be controlled simultaneously and remotely on the same network. Production data and diagnostic information can also be collected. The transceiver is PLC compatible and also CC-Link and EtherNet/IP compliant. A software tool is supplied free of charge. It has been designed to configure all units connected to the network via wireless communication and store their operating parameters in up to 100 setup recipes. As there is no need for communication cables, the units have a small footprint and can be easily installed in places that are difficult or dangerous to access, such as high places or where it is difficult to run cables. A range of transceivers, repeater hubs and cables are available to simplify connection and reduce electrical work. Typical applications for the RD7 Positioner include changeovers on packaging and bottling lines, filling machines, pharmaceutical equipment and food processing machinery. As mentioned above, it is also ideal for replacing handwheels and position indicators when retrofitting outdated equipment.
