Monitoring of service interval

During operation of electric drives, mechanical and electrical components are exposed to wear and
tear.
The service interval remaining until the next service (percentage of maintenance interval) of the fol-
lowing components can be monitored:
− DC-link of frequency inverter
− Fan of frequency inverter
1533 Maintenance Note
When the service interval until service has expired (value 0%), the frequency inverter can indicate
− via parameter
Maintenance Note
− output a warning message
The behavior can be set up.
The service interval remaining until service can be displayed via parameters. Service is required as
soon as the remaining service interval until maintenance has expired (value 0%). It must also be
checked if the component must be replaced.

10.3.1 DC-link

Signalling when service is required
The DC-link of the frequency inverter is equipped with electrolyte capacitors. The service interval for
electrolyte capacitors is mainly defined by the temperature. In high temperatures the electrolytic liquid
will evaporate, which reduces the capacitance of the capacitor. The temperature inside the electrolyte
capacitor depends on two factors: the ambient temperature and the internal heating caused by cur-
rent ripple. The temperature of the electrolyte capacitors is measured by a sensor, so that high ambi-
ent temperatures are taken into account for service interval calculation.
