Material Handling / Drive Control

Drive Solutions with AS-Interface

The internationally standardized AS-Interface (ASi) wiring system has long become established in materials handling. Countless companies are benefiting from the easy installation, high flexibility and low costs of ASi.

LIP Bygningsartikler saves now 22% of the total cost on their conveyor modules thanks to an ASi solution from Bihl+Wiedemann. Each module and the complete system is connected through an ASi network with integrated safety from Bihl+Wiedemann. New conveyor modules can be added simply without additional wiring from the main PLC.

Controlling DC motors directly

The ASi motor modules by Bihl+Wiedemann offer a variety of drive solutions. For example, 24 V motor rollers can be controlled directly via ASi. No additional control unit is required. Motor modules by Bihl+Wiedemann will save you valuable time and costs during commissioning and service.

Decentralised control of AC motors

There is also the option of decentralized control of drives with or without a frequency converter. This flexibility allows for the implementation of new, simpler, system structures. The following example shows how the ASi modules can be used in real applications.
