It is vital that you ensure that the motor housing is safely earthed to the PE (protective
earth) busbar in the switch cabinet. Risk of electric shock. Without low-resistance earthing
no personal protection can be guaranteed and there is a risk of death from electric shock.
Not having optical displays does not guarantee an absence of voltage. Power connections
may carry voltage even if the motor shaft is not rotating.
Do not unplug any connectors during operation. There is a risk of death or severe injury
l
from touching exposed contacts. Power connections may be live even when the motor
shaft is not rotating. This can cause flashovers with resulting injuries to persons and dam-
age to the contacts.
After disconnecting the servo amplifier from the supply voltage, wait several minutes
l
before touching any components which are normally live (e.g. contacts, screw con-
nections) or opening any connections.
The capacitors in the servo amplifier can still carry a dangerous voltage several minutes
l
after switching off the supply voltages. To be quite safe, measure the DC-link voltage
and wait until the voltage has fallen below 60 V.
Built-in holding brakes do not ensure functional safety!
Hanging loads (vertical axes) require an additional, external mechanical brake to ensure
l
personnel safety.
