Heatsink
The module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. When necessary,
contact ABB for cleaning of the heatsink.
Fan
The lifespan of the cooling fan of the drive module is about 50 000 hours. The actual
lifespan depends on the running time of the fan, ambient temperature and dust
concentration. See the appropriate Firmware Manual for the actual signal which
indicates the running time of the cooling fan. For resetting the running time signal
after a fan replacement, please contact ABB.
Replacement fans are available from ABB. Do not use other than ABB specified
spare parts.
