Issue:
Is the cooling fan on ATV312 drive running all the time?
Product Line:
ATV312
Environment:
All model numbers, all serial numbers
Cause:
N/A
Resolution:
The fan starts automatically when the drive controller is commanded to run (receives a run command and a speed reference). It stops a few seconds
after the drive controller is stopped (when output frequency is less than 0.5 Hz and DC injection braking is completed). Not all units have a cooling fan.
NOTE: The fan may start without a run command if the drive controller temperature exceeds allowable limits.
