Technical description
6.8
Stop/Emergency Stop Function to EN 60204
With the personnel safe restart lock –AS- (see page 69 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.
6.8.1
Stop: Standards
The Stop function is used to shut down the machine in normal operation. The Stop functions are
defined by EN 60204 (VDE 0113), paragraphs 9.2.2 and 9.2.5.3.
Category 0:
Category 1:
Category 2:
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.
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.

Shut-down by immediate switching-off of the energy supply to the
drive machinery (i.e. an uncontrolled shut-down);
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.
