Frequently Asked Questions (FAQ)

1. What makes this encoder “safe” compared to standard encoders?

This encoder uses two redundant scanning systems inside one housing. Therefore, it performs internal cross-validation on every measurement. As a result, it detects any internal fault immediately and stops safely.

2. What safety level can I achieve with this encoder?

The PFH value is 1.45×10⁻⁹ per hour. Consequently, you can use it in SIL 3 systems per IEC 61508. For machine safety, it meets Performance Level e (PLe) per EN ISO 13849.

3. Can I use this encoder at temperatures below 0°C?

Yes, the working temperature range is -20°C to +70°C. Therefore, it works in cold storage and outdoor applications. However, keep the storage temperature between -30°C and +80°C.

4. How do I set the safe integration time correctly?

First, consider your machine’s stopping time. Then, set the safe integration time between 50 and 500 ms. A shorter time gives faster reaction but may cause nuisance trips. Start with 200 ms and adjust downward gradually.

5. What is the difference between IRT and RT mode?

IRT (Isochronous Real-Time) provides deterministic cycle times as low as 1 ms. RT (Real-Time) is slightly slower but still very fast. Both work well for safety applications. Choose IRT for servo drives requiring synchronized motion.

6. Which incremental pulse count should I choose?

Options include 4096, 8192, 12288, 16384, or 20480 pulses. Therefore, higher pulse counts give better resolution. However, they also require faster controller processing. For most applications, 8192 pulses works well.

7. Is IP54 protection enough for my application?

IP54 protects against dust and water spray from any direction. Consequently, it suits most indoor industrial environments. However, for washdown areas or outdoor rain, choose a higher IP rating like IP65 or IP67.

Selection Guide

• Choose CDV75M-00012 when you need PROFINET with PROFIsafe safety communication.
• Pick this model for applications requiring two redundant scanning systems.
• Select this encoder for SIL 3 or Performance Level e systems.
• Consider this unit for operating temperatures from -20°C to +70°C.
• Add the sine/cosine output option if you need analog speed feedback.
• For shaft connection, match your existing 10 mm keyway coupling exactly.
• Avoid this encoder if you need SSI interface or higher than 6000 rpm speed.
