AKD PDMM User Guide | 10.5.1.1 Stop
Functional safety, e.g. with hanging load (vertical axes), requires an
additional mechanical brake which must be safely operated, for exam-
ple by a safety control.
Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the
motor holding brake (=> p. 1) immediately after faults or Hardware Dis-
able.
10.5.1.1 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 (see page 1) the drive can be stopped using its inter-
nal electronics (IEC 61508 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.
