Causes
Possible Solutions
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.
End2
Iron Core Saturation
Coefficient
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.
Auto-Tuning results were not in
the applicable parameter setting
range, and
E2-07
or
E2-08
[Motor Saturation Coefficient
2]
have temporary values.
•
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.
End3
Rated Current Setting
Alarm
The rated current value is
incorrect.
Do Auto-Tuning again and set the correct
rated current shown on the motor
nameplate.
End4
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 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.
•
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.
End5
Resistance Tuning
Error
The Auto-Tuning results of the
Line-to-Line Resistance were
not in the applicable range.
•
Make sure that the input motor
nameplate data is correct.
•
Examine and repair damaged motor
wiring.
End6
Leakage Inductance
Alarm
The Auto-Tuning results were
not in the applicable parameter
setting range.
Make sure that the input motor
nameplate data is correct, and do Auto-
Tuning again.
