3 1-encoder Safety Linear motors / torque motores Measuring system analog interface Sensor Module Cabinet-Mounted (SMC) Sensor Module External (SME) Page 3 Measuring system DRIVE-CLiQ interface Serial interface DRIVE-CLiQ Diagnostics of the measuring system Failsafe bus protocol Development acc. to SIL2 resp. PL d PFH value Acknowledgment of interface conformity

4 2-encoder Safety Motor with DRIVE-CLiQ interface (SMI/DQI) SMI/DQI SMI/DQI with analog interface 1) with DRIVE-CLiQ interface Diagnostics of the measuring system Failsafe bus protocol Development acc. to SIL2 resp. PL d PFH value Acknowledgment of interface conformity 1) 1) If the encoder is not mounted in a failsafe (safety-relevant) fashion, a higher PFH value must be observed Page 4

5 2-encoder Safety Single Channel Safety Encoder (SCSE) SMI/DQI Single Channel Safety Encoder (SCSE) as 2nd encoder Development according to 1 is sufficient It must be guaranteed that the encoder value is transferred in a safety-relevant fashion Interfaces in conformance with DQI From SW release 4.7 SP2 HF1 Safety-relevant encoder mounting (FMEA) 1) This encoder can only be used in a 2-encoder safety configuration 1) If the encoder is not mounted in a failsafe (safety-relevant) fashion, a higher PFH value must be observed Page 5

6 Safety Integrated with SMC 40/EnDat 2.2 SMC 40 SMC 40 SMC 40 Requirements placed on measuring systems with EnDat 2.2 Measuring system diagnostics Safety-relevant encoder mounting (FMEA)1) 2) Developed according to SIL2 or PL d with PFH value From SW release 4.7 SP2 HF1 1) Precondition for 1-encoder safety configurations 2) A higher PFH has to be taken into consideration if, for 2-encoder safety configurations, the encoder is not mounted in a safety-relevant function Page 6

7 PFH values for evaluation according to ISO or EN encoder safety Fault exclusion for the encoder mounting PFH = x (SMI; integrated interface) PFH = x (DQI; highly integrated interface) 2-encoder safety Fault exclusion for the mounting of both encoders PFH = 7.00 x Single channel safety encoder as second encoder; fault exclusion for the mounting of both encoders PFH = x no fault exclusion for the encoder mounting PFH = 7.00 x x (if one encoder is not mounted in a safety-relevant fashion) PFH = 7.00 x x x (if both encoders are not mounted in a safety-relevant fashion) Single-channel safety encoder; no fault exclusion for the encoder mounting PFH = x x (if one encoder is not mounted in a safety-relevant fashion) PFH = x x x (if both encoders are not mounted in a safety-relevant fashion) Page 7
