3.3 Stop / Emergency Stop / Emergency Off

The control functions Stop, Emergency Stop and Emergency Off are defined by IEC 60204.
Notes for safety aspects of these functions can be found in ISO 13849 and IEC 62061.
The parameter AXIS#.DISMODE must be set to implement the different stop categories.
Consult the WorkBench Online Help for configuring the parameter.
Serious injury could result when the load is not properly blocked. With vertical load the load
could fall.

3.3.1 Stop

The stop function shuts down the machine in normal operation. The stop function is defined
by IEC 60204.
The Stop Category must be determined by a risk evaluation of the machine.
Stop function must have priority over assigned start functions. The following stop categories
are defined:
Stop Category 0
Shut-down by immediate switching-off the energy supply to the drive machinery (this is an
uncontrolled shut-down). With the safety function STO (➜ # 127) the drive can be stopped
using its internal electronics (IEC 62061 SIL2).
Stop 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.
Stop Category 2
A controlled shut-down, whereby the energy supply to the drive machinery is maintained.
Stop Category 0 and Stop Category 1 stops must be operable independently of the operating
mode, whereby a Category 0 stop must have priority.
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.

No functional safety!
Functional safety, e.g. with hanging load (vertical axes), requires an additional mech-
anical brake which must be safely operated, for example by a safety control.
Set parameter AXIS#.MOTOR.BRAKEIMM to 1 with vertical axes, to apply the motor
holding brake (➜ # 82) immediately after faults or Hardware Disable.
