WARNING
Warning of unguarded moving machine parts!
The drive shaft of the motor moves machine parts with or without sharp
edges.
You could get caught in the rotating drive shaft and incur crushes and cuts.
•
Make sure that there will be no danger to persons or damage to
property even if the drive starts moving unintentionally.
•
To this end, install a second set of limit switches to interrupt the motor
power supply.
•
Never touch a rotating drive shaft.
•
Do not wear lose-fitting clothing.
•
Do not wear gloves.
Follow the steps below to continue the commissioning procedure:
1. A possibly existing holding brake must be checked for proper functioning (apply
DC 24 V, the brake must be released then).
2. Check to see whether the rotor of the motor can be turned easily (a possibly existing
brake must be released beforehand). Watch out for unusual scraping noises.
3. Carry out any other checks specific to or required for your system.
4. Put the drive into operation according to the user manual of the servo amplifier and
servo motor.
5. When using multi-axis systems, put each drive unit - servo amplifier/motor - into
operation separately.

WARNING
Warning of electric shock!
Capacitors can still have dangerous voltages present up to five minutes
after switching off the operating voltage!
The residual voltage of the capacitors can cause muscle cramps, burns,
unconsciousness, respiratory arrest or death.
•
For safety reasons, measure the voltage in the DC link and wait until
the voltage drops below DC 40 V.
•
Always
wait at least 7 minutes after switching off before you disconnect
the device from the mains or unplug connectors.
•
Always
wait at least 10 minutes after switching off before you
disconnect the terminals and touch the contacts.
After commissioning, reinstall the protective cover provided and check that all live connections are
securely protected against contact.
