Commissioning and operation
Before commissioning after longer storage periods, measure the insulation resistance. In
case of values 1k per volt of rated voltage, dry winding.
For trial run without output elements, lock the featherkey. Do not deactivate 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.
Vibrational severities v
eff
3.5 mm/s (P
r
15 kW) or 4.5 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 channels regularly.
Shaft sealing rings and roller bearings have a limited service life.
Regrease bearings with relubricating devices while the low-voltage machine is running.
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.
