Stop- / Emergency Stop- Function to IEC 60204

With the personnel safe function STO (see page 37 onwards) the drive can be
secured on standstill (torque-free) using its internal electronics so that even when
power is being supplied, the drive shaft is protected against unintentional restart
(SIL CL 2 according to IEC 62061, PLd CAT 3 according to ISO 13849-1).
The parameters "STOPMODE" and "ACTFAULT" must be set to 1 in order to
implement the stopand emergency stop categories. If necessary, change the
parameters via the terminal screen of the setup software and store the data in the
EEPROM.

Emergency Stop
6.8.1

Stop: Standards

The Stop function is used to shut down the machine in normal operation. The Stop func-
tions are defined by IEC 60204.
Category 0:
Category 1:
Category 2:
The Stop Category must be determined by a risk evaluation of the machine. In addition,
suitable means must be provided to guarantee a reliable shut-down.
Category 0 and Category 1 Stops must be operable independently of the operating mode,
whereby a Category 0 Stop must have priority. Stop functions must be implemented by
disconnection of the appropriate circuitry, and have priority over assigned start
functions.
If necessary, provision must be made for the connection of protective devices and
lock-outs. If applicable, the Stop function must signal its status to the control logic. A reset
of the Stop function must not create a hazardous situation.
