Vibration severities v
rms
£ 3.5 mm/s (Pr £ 15 kW) or 4.5mm/s (Pr > 15 kW) are acceptable in
coupled mode operation. In case of deviations from normal operation, e.g. increased
temperatures, noises, vibration, find the cause and, if necessary, contact the
manufacturer. Do not switch off the protection devices, not even for trial runs. Switch off
the machine in problematic situations.
If the drive is exposed to dirt, clean it regularly.
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 drive end; IP23 drive and non−drive end), remove the plug before commissioning. Seal
the bore holes with grease. Replace the prelubricated bearings (2Z−bearings) after approx.
10,000 h (2pole) or 20,000 h (multi−pole), but no later than after three to four years or
according to the manufacturer’s instructions.
