HFI Alarm
•
Inductance saliency ratio (
E5-07
/
E5-06
) is too
small.
•
The drive cannot find the
n8-36 [HFI Frequency
Level for L Tuning]
value.
•
Set the correct value on the motor nameplate to
E5-xx [PM
Motor Settings]
or do rotational/stationary Auto-Tuning.
•
When it is necessary to set
n8-35 = 1 [Initial Pole Detection
Method = High Frequency Injection]
or
n8-57 = 1 [HFI Overlap
Selection = Enabled]
, make sure that there is no unusual noise in
the low speed range (10% or less) and that the motor does not
rotate in reverse at start.
Note:
If the drive detects
End8
, it will automatically set
n8-35 =0
[Pull-in] and n8-57 = 0 [Disabled]
. Do not change the settings
unless necessary.
