AKM2G Instructions | 1 English
Earthing! High voltages!
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 per-
sonal 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 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 damage to the con-
tacts.
After disconnecting the servo amplifier from the supply voltage, wait several minutes before
touching any components which are normally live (e.g. contacts, screw connections) or open-
ing any connections.
The capacitors in the servo amplifier can still carry a dangerous voltage several minutes 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.
Secure hanging loads!
Built-in holding brakes do not ensure functional safety!
The user should consider required local safety standards in the case of hanging loads (ver-
tical axes) and the need to insure personnel safety by using additional safety measures for
hazard avoidance.
