6.8 Stop- / Emergency Stop- Function to IEC 60204
With the personnel safe, certified safety function STO (see page 35 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 and
Emergency Stop Function".
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: Shut-down by immediate switching-off of the energy supply to the
drive machinery (i.e. an uncontrolled shut-down);
Category 1: 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;
Category 2: A controlled shut-down, whereby the energy supply to the drive
machinery is maintained.
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.
Examples for implementation can be found in the Product WIKI on page "Stop and
Emergency Stop Function".
