Lenze — 3.2 General safety and application instructions for Lenze motors

Safety instructions General safety and application instructions for Lenze motors 3 3.2 Commissioning and operation Before commissioning after longer storage periods, measure insulation resistance. In case of values ≤ 1 k Ω per volt of rated voltage, dry winding. Fortrialrunwithoutoutputelements,lockthefeatherkey.Donotdeactivate the protective devices, not even in a trial run. Check the correct operation of the brake before commissioning low-voltage machines with brakes. Integrated thermal detectors do not provide full protection for the machine. If necessary, limit the maximum current.

Parameterise the controller so that the motor will be switched off with I > I r after a few seconds of operation, especially at the risk of blocking. Vibrationalseveritiesv eff ≤ 3.5 mm/s(P r ≤ 15 kW)or4.5 mm/s(P r > 15 kW)are acceptable if the clutch is activated. If deviations from normal operation occur, e.g. increased temperatures, noises, vibrations, find the cause and, if required, contact the manufacturer. In case of doubt, switch off the low-voltage machine. If the machine is exposed to dirt, clean the air paths regularly. Shaft sealing rings and roller bearings have a limited service life.

Only use the grease recommended by the manufacturer. If the grease drain holes are sealed with a plug, (IP54 drive end; IP23 drive and non-drive end), remove plug before commissioning. Seal bore holes with grease. Replace prelubricated bearings (2Z bearing) after approx. 10,000 h - 20,000 h, at the latest however after 3 - 4 years.
