Speed and standstill monitoring using a suitable encoder, automatic mode; in the case of
manual start, ON button at T4 / ST; in the case of autostart, jumper at T4 / ST; suitable up to SIL
3, performance level e, SK 4 (a requirement for SK 4 is that in the case of longer standstill times
(standstill time > 24 h), a start-up test must be carried out).
