The safety data has been calculated based on the motor control profile as described in standard IEC
62380:2004, table 5.8.3. Use linear interpolation to calculate the values for intermediate altitudes.
Note:
For drive-specific STO safety data, see drive HW manual.
Relevant failure modes
Random hardware failures in FSPS-21 can prevent the activation of the STO output. The
probability of those and the coverage of the diagnostics is documented in the safety data
table above.
