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.
Auto-Tuning results were not in
the applicable parameter setting
range, and E2-07 or E2-08
[Motor Saturation Coefficient
2] have temporary values.
The rated current value is
incorrect.
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.
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.

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.
• 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.
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.
