Chapter 6 Fault tracking

6.1 Fault prevention

This chapter describes how to carry out preventive maintenance on VFDs.

6.1.1 Periodical maintenance

If the VFD is installed in an environment that meets requirements, little maintenance is needed.

The following table describes the routine maintenance periods recommended by INVT. For
more detailed information on maintenance, please contact us.
