S300 Instructions Manual | 7 Technical description

7.8 Stop-, Emergency Stop-, Emergency Off Function to IEC 60204

With the functional safe, certified function STO (➜ # 38) the drive can be secured on stand-
still (torque-free) using its internal electronics so that even when power is being supplied, the
drive shaft is protected against unintentional restart (up to SIL CL3 according to IEC 62061,
PLe according to ISO 13849-1).
The parameters "STOPMODE" and "ACTFAULT" must be set to 1 in order to implement the
stop and emergency stop categories. If necessary, change the parameters via the terminal
screen of the setup software and store the data in the EEPROM.
Examples for implementation can be found in the KDN on page
Function.

7.8.1 Stop

The Stop function is used to shut down the machine in normal operation. The Stop functions
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, suit-
able 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 dis-
connection 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.
Examples for implementation can be found in the KDN on page
Function.

Shut-down by immediate switching-off of the energy supply to the drive
machinery (i.e. an uncontrolled shut-down); this can be done with the built-in
STO functionality (➜ # 38) .
A controlled shut-down , whereby the energy supply to the drive machinery
is maintained to perform the shut-down, and the energy supply is only inter-
rupted when the shut-down has been completed;
A controlled shut-down, whereby the energy supply to the drive machinery is
maintained.
