Vibration severities v
rms
≤ 3.5 mm/s (P
r
≤ 15 kW) and 4.5 mm/s (P
r
>15kW)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 to the option switch-off after
several seconds of operation at I > I
r
, especially 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 drive end; IP23 drive end 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 - 20,000 h, at the
latest however after 3 - 4 years. Observe the manufacturer’s instructions.
