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.

End1
Excessive Rated Voltage Setting
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%.
•
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.

Adjusted Slip Calculation Error
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 secondary resistor measurement results were not
in the applicable range.
•
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.

No-Load Current Alarm
The Auto-Tuning results of the motor no-load current
value were not in the applicable range.
Examine and repair damaged motor wiring.
Auto-Tuning results were less than 5% of the motor
rated current.
Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.

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.
