The drive’s main cooling fan has a life span of about 60,000 operating hours at
maximum rated operating temperature and drive load. The expected life span
doubles for each 10 °C (18 °F) drop in the fan temperature (fan temperature is a
function of ambient temperatures and drive loads).
Fan failure can be predicted by the increasing noise from fan bearings and the
gradual rise in the heatsink temperature in spite of heatsink cleaning. If the drive is
operated in a critical part of a process, fan replacement is recommended once these
symptoms start appearing. Replacement fans are available from YORK. Do not use
other than YORK specified spare parts.
