Causes
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%.
The motor nameplate data entered during Auto-
Tuning is incorrect.
The rated current value is incorrect.
The Auto-Tuning results were not in the applicable
parameter setting range.
The Auto-Tuning results of the Line-to-Line
Resistance were not in the applicable range.
The Auto-Tuning results were not in the applicable
parameter setting range.
The Auto-Tuning results of the motor no-load current
value were not in the applicable range.
The motor nameplate data entered during Auto-
Tuning is incorrect.
The motor nameplate data entered during Auto-
Tuning is incorrect.
You pushed during Auto-Tuning.
The Auto-Tuning results were not in the applicable
parameter setting range.
The Auto-Tuning results were not in the applicable
parameter setting range.
The motor nameplate data entered during Auto-
Tuning is incorrect.
The motor did not accelerate for the specified
acceleration time.
There is defective drive and motor wiring.
The torque reference during acceleration is too high
(100%).
There is a phase loss in the drive input power. (U/T1,
V/T2, W/T3)
The motor rated current value is incorrect.
The drive could not complete tuning for leakage
inductance in fewer than 300 s.
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
During Inertia Tuning, the output torque was more
than the value set in L7-01 to L7-04 [Torque Limit].
18 Troubleshooting
Possible Solutions
• 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.
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Do Auto-Tuning again and set the correct rated current shown on the
motor nameplate.
• 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.
• Make sure that the input motor nameplate data is correct.
• Examine and repair damaged motor wiring.
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
Examine and repair damaged motor wiring.
• Make sure that the motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
• Make sure that the motor nameplate data entered in Auto-Tuning
is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Auto-Tuning did not complete correctly. Do Auto-Tuning again.
• Examine and repair motor wiring.
• Disconnect the machine from the motor and do Rotational Auto-
Tuning again.
• Examine and repair motor wiring.
• Disconnect the machine from the motor and do Rotational Auto-
Tuning again.
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Increase the value set in C1-01 [Acceleration Time 1].
1.
2. Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
Examine and repair motor wiring.
• Increase the value set in C1-01 [Acceleration Time 1].
• Disconnect the machine from the motor and do Rotational Auto-
Tuning again.
Examine and repair motor wiring.
Correctly set the rated current indicated on the motor nameplate and
do Auto-Tuning again.
Examine and repair motor wiring.
Decrease the value set in C5-01 [ASR Proportional Gain 1].
• 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.
