Auto-Tuning Errors

This table gives information about errors detected during Auto-Tuning. If the drive detects an Auto-Tuning error, the
keypad will show the error and the motor will coast to stop. The drive will not send notification signals for faults and
alarms when Auto-Tuning errors occur.
Two types of Auto-Tuning errors are: Endx and Erx. Endx identifies that Auto-Tuning has successfully completed
with calculation errors. Find and repair the cause of the error and do Auto-Tuning again, or set the motor parameters
manually. You can use the drive in the application if you cannot find the cause of the Endx error.
Erx identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning again.

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%.
Causes
The motor nameplate data entered during Auto-
Tuning is incorrect.
Auto-Tuning results were not in the applicable
parameter setting range, and E2-07 or E2-08 [Motor
Saturation Coefficient 2] have temporary values.
Causes
The rated current value is incorrect.
Causes
The Auto-Tuning results were not in the applicable
parameter setting range.
The motor rated slip that was measured after
Stationary Auto-Tuning was 0.2 Hz or lower.
The motor rated slip that was measured after
compensation with E2-08 [Motor Saturation
Coefficient 2] is not in the applicable range.
The secondary resistor measurement results were not
in the applicable range.
Causes
The Auto-Tuning results of the Line-to-Line
Resistance were not in the applicable range.
Causes
The Auto-Tuning results were not in the applicable
parameter setting range.
A1-02 [Control Method Selection] setting is not
applicable.
Causes
The Auto-Tuning results of the motor no-load current
value were not in the applicable range.
Auto-Tuning results were less than 5% of the motor
rated current.

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.
Possible Solutions
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
• Examine and repair damaged motor wiring.
• If you can uncouple the motor and load, remove the motor from
the machine and do Rotational Auto-Tuning again.
Possible Solutions
Do Auto-Tuning again and set the correct rated current shown on the
motor nameplate.
Possible Solutions
• 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.
Possible Solutions
• Make sure that the input motor nameplate data is correct.
• Examine and repair damaged motor wiring.
Possible Solutions
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
• Examine the value set in A1-02.
• Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
Possible Solutions
Examine and repair damaged motor wiring.
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
