6.1.2 Cooling fan
The VFD
’s cooling fan has a minimum life span of 25,000 operating hours. The actual life span
depends on the VFD usage and ambient temperature. The operating hours can be found
through
P07.14
(accumulative hours of the VFD).
Fan failure can be predicted by the increasing noise from the fan bearings. If the VFD is
operated in a critical part of a process, fan replacement is recommended once these
symptoms appear. Replacement fans are available from us.
Read and follow the instructions in Chapter 1 "Safety precautions".
Ignoring the instructions would cause physical injury or death, or damage
to the equipment.
1. Stop the VFD and disconnect it from the AC power source and wait for at least the time
designated on the VFD.
2. Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder
slightly upward from its front edge.
3. Disconnect the fan cable. Remove the installation bracket.
4. Install the bracket to the reversed direction. Pay attention the air direction of the VFD and
the fan, as shown in the following figure.
