SIEPCYEUOQ2V01A Q2V Technical Manual
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.
Causes
The motor did not accelerate for the specified
acceleration time.
The value of L7-01 or L7-02 [FW Torque Limit or
RV Torque Limit] is small.
Rotational Auto-Tuning was done with a load that
was more than 30% of the rating connected to the
motor.
Causes
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 speed reference was opposite of the
detected speed.
Causes
The torque reference during acceleration is too high
(100%).
Causes
There is a phase loss in the drive input power. (U/
T1, V/T2, W/T3)
The current exceeded the current rating of the drive.
The output current is too low.
You tried Auto-Tuning without a motor connected
to the drive.
There was a current detection signal error.
Causes
The motor rated current value is incorrect.
The drive could not complete tuning for leakage
inductance in fewer than 300 seconds.
Causes
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
Causes
During Inertia Tuning, the output torque was more
than the value set in L7-01 to L7-04 [Torque Limit].
7.7 Auto-Tuning Errors
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.
Possible Solutions
1. Increase the value set in C1-01 [Accel 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.
Possible Solutions
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.
Possible Solutions
• Increase the value set in C1-01 [Accel Time 1].
• Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
Possible Solutions
Examine and repair motor wiring.
• 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 the manufacturer or your
nearest sales representative.
Connect the motor and do Auto-Tuning.
Replace the control board or the drive. For information about
replacing the control board, contact the manufacturer or your
nearest sales representative.
Possible Solutions
Correctly set the rated current indicated on the motor nameplate
and perform Auto-Tuning again.
Examine and repair motor wiring.
Possible Solutions
Decrease the value set in C5-01 [ASR PGain 1].
Possible Solutions
• 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.
