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.
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.
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.
Er-14
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.
