Operation

Vibration severities v

rms

≤

3.5 mm/s (P

≤

15 kW) and 4.5 mm/s (P

> 15 kW) are acceptable

when the clutch is activated. If deviations from normal operation occur, e.g. incr eased

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

, 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 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.
