Causes
The motor nameplate data
entered during Auto-Tuning is
incorrect.
Auto-Tuning did not complete
in a pre-set length of time.
The Auto-Tuning results were
not in the applicable parameter
setting range.
Rotational Auto-Tuning was
done with a load that was more
than 30% of the rating
connected to the motor.
The motor did not accelerate for
the specified acceleration time.
The value of L7-01 or L7-02
[Forward/Reverse Torque
Limit] is small.
Rotational Auto-Tuning was
done with a load that was more
than 30% of the rating
connected to the motor.
There is defective drive and
motor wiring.
There is defective drive and
encoder wiring.
The machine pulled the motor to
rotate in the opposite direction.
When the torque reference is
100% or higher, the sign of the

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 the motor wiring.
• If the motor and machine are
connected during Rotational Auto-
Tuning, decouple the motor from the
machinery.
• 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.
1. Increase the value set in C1-01
[Acceleration Time 1].
2. Disconnect the machine from the
motor and do Rotational Auto-
Tuning again.
Increase the value set in L7-01 or L7-02.
• 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.
Examine and repair motor wiring.
Examine and repair the wiring to the
encoder.
Disconnect the machine from the motor
and do Rotational Auto-Tuning again.
