identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning again.
Code
Name
Causes
Possible Solutions
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.
End3
Rated Current Setting Alarm
The rated current value is incorrect.
Do Auto-Tuning again and set the correct rated current shown on the
motor nameplate.
End4
Adjusted Slip Calculation Error
The Auto-Tuning results were not in the applicable
parameter setting 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.
End5
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.
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.
End8
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]
, 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]
. Do not change the settings unless necessary.
End9
Initial Pole Detection Alarm
The drive cannot calculate the correct value for
n8-84
[Polarity Detection Current]
during High Frequency
Injection Tuning.
When
n8-35 = 1 [Initial Pole Detection Method = High Frequency
Injection]
, make sure that the motor does not rotate in reverse at
start.
Note:
If the drive detects
End9
, it will automatically set
n8-35 =0
[Pull-in]
. Do not change the settings unless necessary.
Er-01
Motor Data Error
The motor nameplate data entered during Auto-
Tuning is incorrect.
•
Make sure that the motor nameplate data is correct.
•
Do Auto-Tuning again and correctly set the motor nameplate
data.
Er-02
Drive in an Alarm State
The motor nameplate data entered during Auto-
Tuning is incorrect.
•
Make sure that the motor nameplate data entered in Auto-Tuning
is correct.
•
Do Auto-Tuning again and correctly set the motor nameplate
data.
Er-03
STOP Button was Pressed
During Auto-Tuning,
was pushed.
Auto-Tuning did not complete correctly. Do Auto-Tuning again.
Er-04
Line-to-Line Resistance Error
The Auto-Tuning results were not in the applicable
parameter setting range.
•
Examine and repair motor wiring.
•
Disconnect the machine from the motor and do Rotational Auto-
Tuning again.
Er-05
No-Load Current Error
The Auto-Tuning results were not in the applicable
parameter setting range.
•
Examine and repair motor wiring.
•
Disconnect the machine from the motor and do Rotational Auto-
Tuning again.
Er-08
Rated Slip Error
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.
Er-09
Acceleration Error
The motor did not accelerate for the specified
acceleration time.
1.
Increase the value set in
C1-01 [Acceleration Time 1]
.
2.
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
Er-12
Current Detection Error
There is a phase loss in the drive input power. (U/T1,
V/T2, W/T3)
Examine and repair motor wiring.
Er-13
Leakage Inductance Error
The motor rated current value is incorrect.
Correctly set the rated current indicated on the motor nameplate and
do Auto-Tuning again.
