Recording of the angular position and revolutions by means of Hall sensors – multiturn version with absolute multiturn transmission for up to 4096 revolutions – data output plus parameterisation and diagnosis via PROFINET.
Robust housing manufactured from seawater-resistant aluminium or stainless steel – stainless steel shaft – ball bearing with radial shaft seal-sensor circuit consisting of ASIC with Hall elements – electrical connection via M12 connector or cable outlet. The Profinet interface according to IEC 61158 / 61784 or PNO specifications order No. 2.712 and 2.722, version 2.2, is integrated into the model series TRT absolute encoders. Real time classes 1 – 3 are supported, i.e. Real Time (RT) and Isochronous Real Time (IRT) plus the requirements of conformance class C. Setting the address, baud rate or terminating resistances is not necessary. A name, which is stored in the absolute encoder’s non-volatile memory, is assigned via the PROFINET controller to address the device. The integrated 2-fold switch enables the TWK PROFINET absolute encoders to be used in star, tree and line network topologies.
An exhaustive description of integration into a PROFINET network can be found in the manual TRT12887. In the version with code type “S” the TRT offers a slew ring functionality. This converts the sensor shaft position value into the postion of a slewing ring or a rotary table. The slew ring encoder permits the adjustment of the number of teeths of the slew ring and of the encoder gear-wheel via the encoder parameters. In this way all gear ratios are possible and the encoder can be adapted to any slew ring by the user. The output values are the position of the slew ring in degrees (resolution adjustable) and his velocity in degree / time basis (time basis adjustable).
