Checks before starting up
Before starting up, ensure that
- all connections have been properly made, and the plug connectors are secured against
working loose.
- all motor protection devices are active,
- the drive is not blocked,
- no other possible sources of danger are present,
- the drive is undamaged (no damage from transport/storage),
- the keys in the shaft end (if present) are secured against being thrown out.
6.2
Initial Start up
Observe the start up and commissioning instructions for the converter (e.g. SIMODRIVE,
MASTERDRIVES MC).
Because of the high dynamic performance of the motor, the
system-specific conditions must be observed without fail during the installation and
start up.
1. If present, release the brake by applying the operating voltage.
2. Turn the rotor by hand, the rotor must not grind.
3. Check the optional brake function (open and close).
4. Check the mounting, seating and alignment of the motor.
5. Check the suitability and setting of the output elements for the intended conditions of
use, for example belt tension.
6. Check
that
all
electrical connections and connecting elements are tight, and that their
design complies with regulations.
7. Check that the protective ground conductor and/or the protective earth have been
connected correctly.
8. Check the functional condition of the auxiliary devices present.
9. Check the protection against accidental contact with moving and live parts.
10. If water-cooled: Check that the cooling water circulates (flow rate, temperature).
11. If forced ventilated: Check the working and direction of rotation of the fan.
12. Bring the drive system into operation in accordance with the operating manual for the
converter or inverse rectifier.
13. Check and, if necessary, adjust the filter in the frequency converter.
14. Ensure that the maximum permissible speed n
max
is not exceeded (see type plate for
details). The maximum permissible speed is the highest permissible, short-term
operating speed.
The fitted temperature sensor cannot cater for all possible faults (note the
instructions in the project planning guide).
WARNING
Hazard from rotating rotor!
Protect the output elements against accidental contact!
Secure key (if present) against being thrown out.
NOTICE
The brake is designed for emergency stops (power cut, emergency stop).
It is not permitted to be used as a working brake.
After the motor has been switched off, the brake functions as a holding brake.
