End9
Initial Pole Detection
Alarm
The drive cannot calculate the
correct value for
n8-84
[Polarity Detection Current]
during High Frequency
Injection Tuning.
•
Set the correct value on the motor
nameplate
E5-xx [PM motor
parameters]
or do Stationary/
Rotational Auto-Tuning, and then do
High Frequency Injection Tuning
again.
•
When
n8-35 = 1 [Initial Pole
Detection Method = High Frequency
Injection]
or
n8-57 = 1 [HFI Overlap
Selection = Enabled]
, make sure that
the motor does not rotate in reverse at
start.
If there is unusual noise in the low
speed range (10% or less), increase
n8-41
in increments of 0.5. Set
n8-41
> 0.0
for IPM motors.
Note:
If the drive detects
End9
, it will
automatically set
n8-35 =0 [Pull-in]
and
n8-57 = 0 [Disabled]
. Do not
change the settings unless necessary.
