Frequently Asked Questions (FAQ)

1. What safety level does the TR CDV75M-00002 achieve?
This encoder achieves SIL 3 per DIN EN 61508 and PL e per EN ISO 13849. The complete system PFH is 8.45 × 10⁻¹⁰ 1/h.

2. Can I use this encoder without the safety system?
The safety system is always active with two redundant scanning systems. You can still read standard position and speed via PROFIBUS.

3. What is the maximum cable length for the 4-meter cable?
The pre-attached cable is exactly 4 meters long. You cannot extend the safety-related cable without recertification.

4. How do I adjust the window of difference on the TR CDV75M-00002?
You program the window of difference using PROFIBUS parameters. This value controls the allowed deviation between both scanning systems.

5. Is the incremental track safe or unsafe on this model?
The incremental track is classified as unsafe (standard) on this unit. The safe position and safe speed come only from the PROFIsafe protocol.
