With the TBN model, one rotation (max. 65,536 steps) is recorded. With the subsequent absolute transmission, the TRN shaft encoder reaches a measuring range of up to 4096 rotations. With the CANopen Safety protocol, both the position value and the speed value (SRDO - Safety Relevant Data Object) meet the requirements of SIL2. The values for the redundant system are compared and checked for plausibility. If the check is positive, the output will be normal and bit-inverted. Comprehensive checks using CRC, timing monitoring, voltage monitoring etc. ensure that reliable position and speed values are output. The speed value can be parameterised via the gate time (1 to 1000 ms) depending on the specific application. In the event of a fault, emergency protocols are issued and a fault listing is created. The target function here is to move to a safe state in the event of a fault. This is also referred to as the functional safety of the shaft encoder. The position and speed values (PDO - Process Data Object) are output via the CANopen protocol. TWK-ELEKTRONIK GmbH BismarckstraBe 108 info@twk.de visit us at | twk.de
