IAI's new controller series: R-Unit
R-Unit is the new generation of controllers that are coupled via module connections and are modularly interchangeable.
These include the RSEL program controller for connecting up to 8 actuators (in combination with the REC EC control up to 16 actuators), the RCON position controller for up to 16 electric cylinders and the REC EC controller for motion control of up to 16 EleCylinder axes.
Common to all of them are the linkable control units with identical connections, which allow a free selection and combination of connected electric actuators and their control methods. Mixed control of electric cylinders with 24 volt and 230 volt motors is also easily feasible.
RCON - modular position controller for up to 16 axes
The new compact RCON system is a high-performance controller with modular connection units and easy extendability.
Up to 16 axes with 24V pulse motors and 230V servo motors can be connected together. At the same time, the space requirement is just 1/5 of conventional controllers.
Difference position and program controller
Single-axis or multi-axis controllers are available as simple types that operate like solenoid valves of a pneumatic controller, up to highly functional models that control via program. A basic distinction is made between position and program controllers.
In position controllers, the travel profiles of each individual axis are entered in position tables. They are available as 3-point or multi-point positioning controls for up to 512 adjustable positions.
Program controllers can also be used independently for interpolating axes, Cartesian robots, SCARA robots or for machine control.
2 software programs for all controllers - updates free of charge
Position controllers are operated with the "CON software". It is used to enter the travel profiles of an axes into a position table and to change parameters. With the "SEL software" for program controllers, application programs are created and the connected axes are controlled.
After purchasing the software and registering the serial numbers, customers can download the regular updates free of charge.
Change from incremental to absolute encoder type
With just one connection to the ACON, PCON, ASEL or PSEL controllers, the ABU controler module turns an incremental version into an absolute version. The ABU set consists of an absolute unit, back-up battery and controller connection cable.
By connecting to the ABU control module, the current position of system will be held even if power is disconnected, the actuator can operate immediately without homing. Encoder data is stored for up to 20 days when the system is switched off.
Connection to fieldbus networks
Actuators are connected to fieldbuses such as Profinet, Profibus, EtherCAT or EtherNet/IP or Profibus either via a gateway or directly via a corresponding interface on the controller. The ➥ Network Table shows which controller is compatible with which fieldbus.
Field network configuration files can be downloaded free of charge under ➥ Field Network.
Controller for EtherCAT Motion network
The linkable RCON network controllers, the SCON single-axis controller and the MCON 1-8-axis controller also have an optional EtherCAT motion connection.
This ensures real-time operation, i.e. synchronisation of servo motors. This is suitable for short cycle times of automation systems, for example packaging machines or the assembly of electronic components.
