Compact conveyor roller controller requires no PLC

Beckhoff has released an EtherCAT-based controller for roller conveyor systems that can perform the entire control function without a PLC.

By integrating all necessary functions in the EP7402 EtherCAT box, the control architecture and cabling of roller conveyor systems is said to become significantly more efficient. With a high IP67 protection rating, the compact motor controller for BLDC motors is suitable for conveyor tasks in intralogistics and assembly technology as well as in the packaging, food and beverage industries.

The EP7402 offers two outputs with an integrated motion controller for the direct connection of 24 VDC conveyor roller motors or other brushless DC (BLDC) motors up to 3.5 A. Eight additional digital I/Os enable connection of, for example, photoelectric switches, and communication between the different box modules can operate without a PLC. The EP7402 takes over the complete control of a roller motor independently of the conveyor or motor manufacturer, and the control of the motors is sensorless. Maximum rated current, acceleration or deceleration ramps and various other parameters can be configured, allowing optimal adaptation to different applications.

In conveyor operation the EP7402 can also be operated without a PLC and provides functions such as zero pressure accumulation (ZPA) and single or block discharge. Further EtherCAT devices such as digital and analog I/Os, barcode readers or safety devices can be connected to the additional EtherCAT junction. The EtherCAT box with IP67 protection measures 174 x 60 x 36.5 mm and can be easily mounted in standard C-channel or L-brackets on the conveyor frame. It requires no additional protective covering, which saves additional installation space. Power supply and EtherCAT communication take place via a single cable with a B23 ENP hybrid connector (28 A/45°C current-carrying capacity at up to 45°C).
