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.
Note: The parameter DRV.DISMODE must be set to 2 to implement the different stop categories.
Consult the PACMotion Workbench Online Help for configuring the parameter.
WARNING
No functional safety!
Serious injury could result when the load is not properly blocked. With vertical load the load could
fall.
Functional safety, e.g. with hanging load (vertical axes), requires an additional mechanical brake
which must be safely operated, for example by a safety control.
Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the motor holding brake (➜ #
118) immediately after faults or Hardware Disable.
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.
4.15.1
Stop Category 0
Shut-down by immediate switching-off the energy supply to the drive machinery (this is an
uncontrolled shut-down). With the approved safety function STO (➜ # 54) the drive can be
stopped using its internal electronics (IEC 62061 SIL2).
4.15.2
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.
4.15.3
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.
