YASKAWA TOEPC7106171FD FP605 DRIVE INSTALLATION & PRIMARY OPERATION
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.
• Inductance saliency ratio (E5-07/E5-06) is too
small.
• The drive cannot find the n8-36 [HFI Frequency
Level for L Tuning] value.
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 motor nameplate data entered during Auto-
Tuning is incorrect.
During Auto-Tuning, was pushed.
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 a phase loss in the drive input power. (U/T1,
V/T2, W/T3)
The motor rated current value is incorrect.
20 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.
• 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.
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.
• 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.
1. Increase the value set in C1-01 [Acceleration Time 1].
2. 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.
