2.5.4 Potentially Dangerous Movements
There can be different causes for potentially dangerous
movements:
 mistakes in wiring or cable connection
 software errors
 faulty components
 errors in measuring value and signal encoders
 operating mistakes
The protection of people must be insured by superior means or
monitoring on the plant side. You must not rely on the internal
monitoring in the drive components alone. Monitoring or measures
are to be provided according to a risk and error analysis by the
plant builder according to the specific conditions of the plant. The
valid safety rules for the plant are to be included in this process.
DANGER!
Potentially dangerous movements!
Life hazard, serious injury or material damage!
 No persons are allowed within the motion range of the machine.
This is to be ensured by means of devices like protective fences,
grids, covers or photoelectric barriers.
 The fences and covers must be sufficiently strong to withstand
the maximum possible motion energy.
 The emergency stop switch must be located very close to the
operator. Check the operation of the emergency stop before
starting up the plant.
 Secure against unintentional start by enabling the mains
contactor of the drives via an emergency off circuit or by means
of the function 'safe stop'.
 Before accessing the danger zone, bring the drives to a safe
stop.
 To work on the plant, power must be turned off and locked out.
 Avoid operating high-frequency, remote-control and radio
devices in the vicinity of the plant's electronics and connecting
wires. If the use of those devices is inevitable, check system and
plant for possible malfunctions before first operation. In some
cases a special EMT check may be necessary.
