Heidenhain Corp. (Schaumburg, IL) offers the Leine & Linde DRIVE-CLiQ encoder platform for operation in harsh drive environments where they are exposed to vibration, shock, and mechanical loads. The encoder can be installed to the motor mechanics typically found in heavy-duty applications without any adaptation needed. DRIVE-CLiQ is Siemens’ communication protocol for motor feedback in a SINAMICS drive system. It is an Ethernet-based interface for connection of different kinds of components like motors, frequency converters, and encoders.
The encoder is designed for transfer of both position and speed data over the same protocol. The scanning generates absolute position data, which means that each step of the turn is represented by a unique code; both single-turn for the exact position of the shaft, and multi-turn for the number of full revolutions. Up to five units may be connected to a hub for transfer of data over a common cable.
