EP7402-0057 | 2-channel motor controller box for roller conveyor systems

The EP7402-0057 EtherCAT Box offers two outputs with integrated controller for the direct connection of 24 V DC conveyor roller motors or other BLDC motors with max. 3.5 A. Eight additional digital inputs/outputs enable connection of e.g. photoelectric switches and communication between the box modules in operation without PLC.

The EP7402-0057 takes over the complete control of a roller motor independently of the manufacturer of conveyor or motor. Maximum rated current, acceleration or deceleration ramps and various other parameters can be configured and allow for a wide range of adaptations to different applications. The control of the motors is sensorless. The EtherCAT Box with IP 67 protection rating measures only 174 mm x 60 mm 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. Power supply and EtherCAT communication are realized via a B23 ENP connector with a current carrying capacity of 28 A/45 °C. In conveyor operation the EP7402-0057 can also be operated without PLC and provides functions such as ZPA (Zero Pressure Accumulation), 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.
