The SEW-Eurodrive decentralised drive solutions package comprises a PLC/motion controller or gateway, frequency inverter, optional I/O module, geared motor and interconnection cables to bring drive control and execution closer to the application, reducing the ‘real estate’ requirement in the central control cabinet and the installation, material and maintenance costs associated with wiring inverters back to the central control cabinet.
Frequency inverters are field mounted alongside geared motors and controlled by a decentralised PLC or gateway acting as an interface to a fieldbus-connected supervisory PLC.
Individual cable runs are shortened in a decentralised control system, as high-voltage field wiring is daisy-chained between devices while sensor and actuator connections are localised to the local I/O blocks. Traditional control cabling is eliminated because the communication between machine-based PLC or gateway and the supervisory PLC is achieved through a single fieldbus connection.
The IP55 enclosure, with an integrated mains isolator, enables field mounting of the frequency inverters in close proximity to the load-driving motor.
A CAN-based system bus gateway is also provided to communicate to the fieldbus.
