2 Product overview
2.1 Introduction
2-channel motor controller box for roller conveyor systems
The EP7402-0057 EtherCAT Box offers two outputs with integrated MDR 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 IP67 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.
NOTE
Brake chopper required
Overvoltage peaks can occur on the supply voltage U
P
which can destroy the device.
The overvoltage peaks occur during braking operations of the motor or by manually moving objects on the
roller conveyor.
• Use a brake chopper to dissipate overvoltages.
