1.5 Principle of the safety function

System safety is established as follows:

– Each of the two scanning channels is largely fail-safe thanks to individual diagnostic

measures.

– The measuring system internally compares the positions detected by both channels in two

channels and determines the velocity in two channels and transfers the safe data in the CIP

Safety™ protocol via EtherNet/IP™.

– In the event of a failed channel comparison or if another error is detected through the internal

diagnostic mechanisms, the measuring system switches the CIP Safety™ channel to error

status.

– Initialization of the measuring system and execution of the preset adjustment function are

appropriately safeguarded.

– The control additionally checks whether the obtained position data are within the position

window expected by the control. Unexpected position data are, e.g., position jumps, tracking

error deviations and incorrect direction of travel.

– In case errors are detected, the control introduces appropriate safety measures defined by the

system manufacturer

– The system manufacturer ensures, through correct attachment of the measuring system, that

the measuring system is always driven by the axis to be measured and is not overloaded.

– The system manufacturer performs a safeguarded test during commissioning and whenever a

parameter has been changed.
