Attention
: Strong speed step without speed ramp can damage bearings or
can excite natural frequency.
4.2.6.
Once the motor is fixed on its frame and linked with the driven load, it is highly recommended to check complete
shaft line balancing to minimize vibrations.
Shaft line balancing and vibration control
Moreover, it is highly recommended to implement a vibratory control in accordance with the ISO 10816
standard: the efficient speed vibration on the frequency range between 10 to 1000Hz must not run over 2.8
mm/s for an endless supply.
The motor has to be tested on the whole speed range in order to detect a potential natural frequency with the
frame.
Rotation speed for which a resonance appears have to be avoided or the resonance has to be suppressed.
4.3. Electrical connection
Warning
: Check that the power to the electrical cabinet is safely off prior to make any
connections.
Warning
: The wiring must comply with the drive commissioning manual, with
recommended cables, the standard and the local regulations
Warning
: The high-speed motor must be grounded by connecting to an unpainted section
of the motor.
Danger:
After 15 days, check all tightening torques on cable connection. Bad connections
can lead to overheating and fire.
Please, read
§3.7 "Electrical connection"
to have information about cable recommendations.
A lot of information are already available in the drive documentations.
The motor has to be connected to the drive in accordance with its commissioning manual
.
