7.7 Auto-Tuning Errors
292 YASKAWA SIEPC71061753C GA500 Technical Manual
Code Name Causes Possible Solutions
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 E5-xx [PM motor
parameters] or do Stationary/Rotational Auto-Tuning, and
then do High Frequency Injection Tuning again.
• When it is necessary to set n8-35 = 1 [Initial Pole Detection
Method = High Frequency Injection] or n8-57 = 1 [HFI
Overlap Selection = 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.
If there is unusual noise in the low speed range (10% or less),
increase n8-41 in increments of 0.5. Set n8-41 > 0.0 for IPM
motors.
Note:
If the drive detects End8, it will automatically set n8-35 =0
[Pull-in] and n8-57 = 0 [Disabled]. 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.
• Set the correct value on the motor nameplate E5-xx [PM motor
parameters] or do Stationary/Rotational Auto-Tuning, and
then do High Frequency Injection Tuning again.
• When n8-35 = 1 [Initial Pole Detection Method = High
Frequency Injection] or n8-57 = 1 [HFI Overlap Selection =
Enabled], make sure that the motor does not rotate in reverse
at start.
If there is unusual noise in the low speed range (10% or less),
increase n8-41 in increments of 0.5. Set n8-41 > 0.0 for IPM
motors.
Note:
If the drive detects End9, it will automatically set n8-35 =0
[Pull-in] and n8-57 = 0 [Disabled]. Do not change the
settings unless necessary.
Code Name Causes Possible Solutions
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.
The combination of the motor rated power and
motor rated current do not match.
• Examine the combination of drive capacity and motor output.
• Do Auto-Tuning again, and correctly set the motor rated power
and motor rated current.
The combination of the motor rated current that was
entered during Auto-Tuning and E2-03 [Motor No-
Load Current] do not match.
• Examine the motor rated current and the no-load current.
• Set E2-03 correctly.
• Do Auto-Tuning again, and correctly set the motor rated
current.
The combination of the setting values of Motor
Base Frequency and Motor Base Speed do not
match.
Do Auto-Tuning again, and correctly set the Motor Base
Frequency and Motor Base Speed.
Code Name Causes Possible Solutions
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.
You did Auto-Tuning while the drive had a minor
fault or alarm.
Clear the minor fault or alarm and do Auto-Tuning again.
There is a defective motor cable or cable
connection.
Examine and repair motor wiring.
The load is too large. • Decrease the load.
• Examine the machine area to see if, for example, the motor
shaft is locked.
The drive detected a minor fault during Auto-
Tuning.
1. Stop Auto-Tuning.
2. Examine the minor fault code and remove the cause of the
problem.
3. Do Auto-Tuning again.
Code Name Causes Possible Solutions
Er-03 STOP Button was Pressed
During Auto-Tuning, was pushed.
Auto-Tuning did not complete correctly. Do Auto-Tuning again.
