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

With the functional safe, certified safety 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.
The parameters "STOPMODE" and "ACTFAULT" must be set to 1 in order to implement
the 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 Product WIKI on page

Stop

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 func-
tions.
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.

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 (see page 37);
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 interrupted when the shut-down has been completed;
A controlled shut-down, whereby the energy supply to the drive
machinery is maintained.
