Auto-Tuning Errors
If the drive detects an Auto-Tuning error, the keypad will show the error and the motor will coast to stop.
The drive will not send notification signals for faults and alarms when Auto-Tuning errors occur.
Two types of Auto-Tuning errors are:
Endx
and
Erx
:
•
Endx
identifies that Auto-Tuning has successfully completed with calculation errors. Find and repair the cause
of the error and do Auto-Tuning again, or set the motor parameters manually. You can use the drive in the
application if you cannot find the cause of the
Endx
error.
•
Erx
identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning
again.

End1
Excessive Rated Voltage Setting
The torque reference was more than 20% during
Auto-Tuning or the no-load current that was
measured after Auto-Tuning is more than 80%.
•
Make sure that the input motor nameplate data is correct.
•
Do Auto-Tuning again and correctly set the motor nameplate
data.
•
If you can uncouple the motor and load, remove the motor
from the machine and do Rotational Auto-Tuning again.
•
If you cannot uncouple the motor and load, use the results
from Auto-Tuning.

End2
Iron Core Saturation Coefficient
The motor nameplate data entered during Auto-
Tuning is incorrect.
•
Make sure that the input motor nameplate data is correct.
•
Do Auto-Tuning again and correctly set the motor nameplate
data.
Auto-Tuning results were not in the applicable
parameter setting range, and
E2-07
or
E2-08 [Mbus
Reg1 Bit Select]
have temporary values.
•
Examine and repair damaged motor wiring.
•
If you can uncouple the motor and load, remove the motor
from the machine and do Rotational Auto-Tuning again.

End4
Adjusted Slip Calculation Error
The Auto-Tuning results were not in the applicable
parameter setting range.
The motor rated slip that was measured after
Stationary Auto-Tuning was 0.2 Hz or lower.
The motor rated slip that was measured after
compensation with
E2-08 [Mbus Reg1 Bit Select]
is
not in the applicable range.
The secondary resistor measurement results were
not in the applicable range.
•
Make sure the input motor nameplate data is correct.
•
Do Rotational Auto-Tuning again and correctly set the motor
nameplate data.
•
If you cannot uncouple the motor and load, do Stationary
Auto-Tuning 2.

Resistance Tuning Error
The Auto-Tuning results of the Line-to-Line
Resistance were not in the applicable range.
•
Make sure that the input motor nameplate data is correct.
•
Examine and repair damaged motor wiring.

End6
Leakage Inductance Alarm
The Auto-Tuning results were not in the applicable
parameter setting range.
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
A1-02 [Control Method]
setting is not applicable.
•
Examine the value set in
A1-02
.
•
Make sure that the input motor nameplate data is correct, and
do Auto-Tuning again.

End7
No-Load Current Alarm
The Auto-Tuning results of the motor no-load
current value were not in the applicable range.
Examine and repair damaged motor wiring.
Auto-Tuning results were less than 5% of the motor
rated current.
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.

End8
HFI Alarm
•
Inductance saliency ratio (
E5-07
/
E5-06
) is too
small.
•
The drive cannot find the
n8-36 [HFI Signal
Frequency]
value.
•
Set the correct value on the motor nameplate to
[E5: PM
MOTOR SETTINGS]
or do rotational/stationary Auto-Tuning.
•
When it is necessary to set
n8-35 = 2 [InitRotorPos Selection
= HiFreq Injection]
or
n8-57 = 1 [High-Freq Injection =
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 =1
[Pull-In] and n8-57 = 0 [Disabled]
. Do not change the
settings unless necessary.
