Three−phase AC machines
Operation
Vibration severities v
are acceptable when the clutch is activated. If deviations from normal
operation occur, e.g. increased temperatures, noises, vibrations, find the
cause and, if necessary, contact the manufacturer. Switch off the machine
in problematic situations.
If the drive is exposed to dirt, clean it regularly.
Do not switch off the protection devices, not even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary,
limit the maximum current. Connect the function blocks such that the
machine switches off after several seconds of operation at I > I
if blocking may occur.
Shaft seals and bearings have a limited service life.
Regrease the bearings using the relubrication facility while the low−voltage
machine is running. Observe the saponification number. If the grease drain
hole is sealed with a plug (IP54 driven end; IP23 driven end and non−driven
end), remove the plug before commissioning. Seal the bore holes with
grease. Replace the prelubricated bearings (2Z bearings) after approx.
10,000 h − 20,000 h, at the latest however after 3 − 4 years. Observe the
manufacturer's instructions.
