Safety option 30

Due to safety option 30, the following safety functions can be used:

ƒ

Safe torque off (STO),
formerly: safe standstill

ƒ

Safe stop 1 (SS1)

ƒ

Safe stop emergency (SSE)

ƒ

Safe operation mode selector (OMS)

ƒ

Safe enable switch (ES)

The safe disconnection of the drive is achieved through:

ƒ

a higher−level safety PLC via PROFIsafe/PROFINET

ƒ

connected active or passive sensors

The functions of the safety option must be parameterised via the »Engineer«.

The motion functions are continued to be executed by the controller. The drive−based
safety monitors the safe compliance with the limit values. When the limit values are
exceeded, the drive−based safety starts the control functions according to EN 60204−1
directly in the controller.

The safety functions are suitable for applications according to IEC 61508 to SIL 3 and
achieve a performance level (PL) e and the control category 3 according to EN ISO 13849−1.
