Operation
Vibration severities v
rms
≤ 3.5 mm/s (P
r
≤ 15 kW) and 4.5 mm/s (P
r
> 15 kW) 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 such that the machine switches 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 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.
2.2 General safety and application notes for Lenze controllers
(to: Low-Voltage Directive 73/23/EEC)
General
Depending on their degree of protection, some parts of Lenze controllers (frequency
inverters, servo inverters, DC controllers) and their accessory components can be live,
moving and rotating during operation. Surfaces can be hot.
Non-authorized removal of the required cover, inappropriate use, incorrect installation or
operation, creates the risk of severe injury to persons or damage to material assets.
For more information please see the documentation.
All operations concerning transport, installation, and commissioning as well as
maintenance must be carried out by qualified, skilled personnel (IEC 364 and CENELEC HD
384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110 and national regulations for the
prevention of accidents must be observed).
According tothisbasic safetyinformation, qualified, skilledpersonnel are persons whoare
familiar with the assembly, installation, commissioning, and operation of the product and
who have the qualifications necessary for their occupation.
