Recording of the angular position and revolutions by means of Hall sensors – absolute multiturn transmission for up to 4096 revolutions – data output plus parameterisation and diagnosis via EtherCAT.
Robust housing (housing sickness 5 mm) manufactured from seawater-resistant aluminium (AlMgSi1) or stainless steel – stainless steel shaft – ball bearing with shaft seal – sensors circuit consisting of ASIC with Hall elements – electrical connection via M12 connector or cable outlet. In the model series TRK absolute encoders, the EtherCAT interface is integrated according to IEC 61158-2 to 6 and encoder profile CiA DSP406. As a “full slave”, the TRK supports all EtherCAT addressing modes such as logical addressing, position addressing and node addressing.
Use of the CANopen over EtherCAT message and the CANopen encoder profile enable parameter and diagnostic data handling as familiar from CANopen. These are contained in an object directory under the same indices as in the case of CANopen. The process data are transmitted in PDOs whose composition is defined via PDO mapping.
