7.7 Auto-Tuning Errors
274 YASKAWA SIEPC71061753A GA500 Technical Manual
Code Name Causes Possible Solutions
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] or n8-57 = 1 [HFI Overlap Selection =
Enabled] , 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] 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
prblem.
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.
Code Name Causes Possible Solutions
Er-04 Line-to-Line Resistance Error The Auto-Tuning results were not in the applicable
parameter setting range.
Auto-Tuning did not complete in a pre-set length of
time.
There is a defective motor cable or cable
connection.
•
Examine and repair motor wiring.
•
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
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.
Code Name Causes Possible Solutions
Er-05 No-Load Current Error
The Auto-Tuning results were not in the applicable
parameter setting range.
Auto-Tuning did not complete in a pre-set length of
time.
•
Examine and repair motor wiring.
•
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
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.
Rotational Auto-Tuning was done with a load that
was more than 30% of the rating connected to the
motor.
•
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
• If you cannot uncouple the motor and load, make sure that the
load is less than 30% of the motor rating. If a mechanical
brake is installed in the motor, release the brake during
Rotational Auto-Tuning.
