7.7 Auto-Tuning Errors
194 YASKAWA SIEPYEULA5001C LA500 Technical Manual
Code Name Causes Possible Solutions
Er-09 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 .
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.
Code Name Causes Possible Solutions
Er-11 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.
Code Name Causes Possible Solutions
Er-12 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.
Code Name Causes Possible Solutions
Er-13 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.
Code Name Causes Possible Solutions
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.
