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.
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
You pushed
during Auto-Tuning.
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-10
Motor Direction Error
There is defective drive and motor wiring.
Examine and repair motor wiring.
Er-11
Motor Speed Error
The torque reference during acceleration is too high
(100%).
•
Increase the value set in
C1-01 [Acceleration Time 1]
.
•
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.
The drive could not complete tuning for leakage
inductance in fewer than 300 s.
Examine and repair motor wiring.
Er-14
Motor Speed Error 2
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
Decrease the value set in
C5-01 [ASR Proportional Gain 1]
.
Er-15
Torque Saturation Error
During Inertia Tuning, the output torque was more
than the value set in
L7-01 to L7-04 [Torque Limit]
.
•
Increase the value set in
L7-01 to L7-04 [Torque Limit]
as much
as possible.
•
Decrease the values set for the frequency and amplitude of the
test signals used when doing inertia tuning. First, decrease the
test signal amplitude, and then do Inertia Tuning. If the error
continues, decrease the test signal frequency and do Inertia
Tuning again.
