Decentralized drive technology

Synchronization and flying saw

Nord Drivesystems offers decentralized drives that can be used to implement synchronization and flying saws. PLC and positioning control in the frequency inverters enable the synchronization of several drives in master-slave operation.

The flying saw function enables a processing unit to be connected and guided in parallel to a moving workpiece. While the material transport continues on the master axis, the slave axis synchronizes itself and carries out its processing step as soon as synchronization is achieved. It then moves back to the starting position to start the process all over again. This makes it possible to process a workpiece during transportation.

The internal PLC and the Posicon positioning controller can synchronize several drives in master-slave mode. The inverters can determine the current position of the drive. Up to three slave inverters can be controlled by one master inverter as standard.

The networked drives have a wide range of interfaces and are suitable for Industry 4.0 applications. A PLC integrated into the inverters can relieve the higher-level control system and enables a modular automation concept. It is freely programmable and can process the data from connected sensors and actuators and initiate sequence control. The drives can communicate their status data via the controller or to a secure cloud.
