Monitoring for broken shearpins

If the Broken shearpin monitoring option is activated, a shearpin break

is recognised if

both signals of the incremental encoder fall below the set standstill

frequency (standstill)

and

the proximity switch exceeds the set standstill frequency (rotating

shaft).

The recognised broken shearpin leads to safe condition (see status B2

in "Signal statuses" table in Chapter 8 of the operating manual). If indi-

vidual or multiple signals change, the safe condition is cleared again as

required (see "Signal statuses" table).

Hazards that can arise through an automatic restart must be excluded

within the user program.
