Causes
The drive cannot calculate the
correct value for n8-84
[Polarity Detection Current]
during High Frequency
Injection Tuning.
The motor nameplate data
entered during Auto-Tuning is
incorrect.
The combination of the motor
rated power and motor rated
current do not match.
The combination of the motor
rated current that was entered
during Auto-Tuning and E2-03
[Motor No-Load Current] do
not match.
The combination of the setting
values of Motor Base Frequency
and Motor Base Speed do not
match.
The motor nameplate data
entered during Auto-Tuning is
incorrect.
You did Auto-Tuning while the
drive had a minor fault or alarm.

Possible Solutions
• 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.
• Make sure that the motor nameplate
data is correct.
• Do Auto-Tuning again and correctly
set the motor nameplate data.
• Examine the combination of drive
capacity and motor output.
• Do Auto-Tuning again, and correctly
set the motor rated power and motor
rated current.
• Examine the motor rated current and
the no-load current.
• Set E2-03 correctly.
• Do Auto-Tuning again, and correctly
set the motor rated current.
Do Auto-Tuning again, and correctly set
the Motor Base Frequency and Motor
Base Speed.
• Make sure that the motor nameplate
data entered in Auto-Tuning is
correct.
• Do Auto-Tuning again and correctly
set the motor nameplate data.
Clear the minor fault or alarm and do
Auto-Tuning again.
