Positioning systems ensure efficient and reproducible format changes in packaging machines. The modular PowerDRIVE-Box from Lenord, Bauer & Co. GmbH, Oberhausen, is a platform for the automation of secondary axes.
The Central CPU module of the box uses plug-in PORT modules to manage up to 17 Actuators. The two housing variants offer four or nine slots, which can be fitted as required. The box can be expanded via COM modules, resulting in up to 17 ports.
Each drive is connected to a module via just one hybrid cable. Thanks to Separate routing of motor and logic supply communication and diagnostic functions are maintained even when the motor supply is switched off.
To optimise cable lengths, the speakers can be distributed throughout the system. The Grouping actuators The configuration of the distributed boxes enables parts of a system to be switched off safely.
As a subsystem, the modular PowerDRIVE-Box relieves the machine's communication network and optimises the data flow. The CPU module acts as a node for communication with the machine control system (PLC). The Configurable Ethernet-based real-time interface supports communication profiles such as PROFINET, EtherCAT, POWERLINK, EtherNet/IP or Modbus/TCP.
To integrate the system into the machine control system Proven function blocks (FBs) are used. These generate the travel commands required to control the drives and forward status data such as motor current, absolute position, device temperature and threshold values to the PLC. Analysing this device data enables, for example, preventive maintenance of the machine.
The CPU module can also be connected via a USB interface or in conjunction with an optional Network interface (web browser) exchange data. This allows parameter sets to be written to the CPU and status data to be read and processed directly.
