Stop / Emergency Stop / Emergency Off; Stop - Kollmorgen AKD series Installation Manual

7.15 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 DRV.DISMODE must be set to 2 to implement the different stop categories.
Consult the WorkBench Online Help for configuring the parameter.
WARNING
No functional safety!
Serious injury could result when the load is not properly blocked. With ver-
tical 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.

7.15.1 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 approved safety function STO (➜ # 55) 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.
