3.1 Maintenance

3.1.1 Maintenance Intervals

If installed in an appropriate environment, the drive requires very little maintenance. This table lists the routine maintenance
intervals recommended by Baldor.
Maintenance
Check/replace floor mount
enclosure inlet air filter
Check/replace floor mount
enclosure exhaust air filter.
Check and clean heatsink.
Replace drive module fan.
Replace enclosure fan(s).
Replace battery in the
Assistant control panel.

3.1.2 Drive Module Fan Replacement

The drive module fan cools the heatsink. 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 Baldor. Do
not use other than Baldor specified spare parts.
Refer to the installation instructions supplied with the fan kit.
3.1.3 Enclosure Fan Replacement – UL Type / NEMA 12 Floor Mount Enclosures
