Rated Slip Error
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 did not complete in a pre-set length of
time.
The Auto-Tuning results were not in the applicable
parameter setting range.
•
Examine and repair the motor wiring.
•
If the motor and machine are connected during Rotational
Auto-Tuning, decouple the motor from the machinery.
Rotational Auto-Tuning was done with a load that
was more than 30% of the rating connected to the
motor.
•
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.

Acceleration Error
The motor did not accelerate for the specified
acceleration time.
1.
Increase the value set in
C1-01 [Acceleration Time 1]
.
2.
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
The value of
L7-01 or L7-02 [Forward/Reverse
Torque Limit]
is small.
Increase the value set in
L7-01 or L7-02
.

Motor Direction Error
There is defective drive and motor wiring.
Examine and repair motor wiring.
There is defective drive and encoder wiring.
Examine and repair the wiring to the encoder.
The machine pulled the motor to rotate in the
opposite direction.
When the torque reference is 100% or higher, the
sign of the speed reference was opposite of the
detected speed.
Disconnect the machine from the motor and do Rotational Auto-
Tuning again.

Motor Speed Error
The torque reference during acceleration is too high
(100%).
•
Increase the value set in
C1-01 [Acceleration Time 1]
.
•
Disconnect the machine from the motor and do Rotational
Auto-Tuning again.

Current Detection Error
There is a phase loss in the drive input power. (U/
T1, V/T2, W/T3)
Examine and repair motor wiring.
The current exceeded the current rating of the drive.
The output current is too low.
•
Check the motor wiring for any short circuits between the
wires.
•
Check and turn ON any magnetic contactors used between
motors.
•
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest
sales representative.
You tried Auto-Tuning without a motor connected
to the drive.
Connect the motor and do Auto-Tuning.
There was a current detection signal error.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.

Leakage Inductance Alarm
The motor rated current value is incorrect.
Correctly set the rated current indicated on the motor nameplate
and perform Auto-Tuning again.
The drive could not complete tuning for leakage
inductance in fewer than 300 seconds.
Examine and repair motor wiring.

Motor Speed Error 2
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
Decrease the value set in
C5-01 [ASR Proportional Gain 1]
.

Er-15
Torque Saturation Error
During Inertia Tuning, the output torque was more
than the value set in
L7-01 to L7-04 [Torque Limit]
.
•
Increase the value set in
L7-01 to L7-04 [Torque Limit]
as
much as possible.
•
Decrease the values set for the frequency and amplitude of the
test signals used when doing inertia tuning. First, decrease the
test signal amplitude, and then do Inertia Tuning. If the error
continues, decrease the test signal frequency and do Inertia
Tuning again.
