YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Causes
The motor did not accelerate for the specified
acceleration time.
Rotational Auto-Tuning was done with a load that
was more than 30% of the rating connected to the
motor.
Causes
There is a phase loss in the wiring between the output
terminal block (or motor overload) and the motor.
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 s.
Causes
The result of the induced voltage tuning was not in
the applicable range.
Causes
The motor data is incorrect.
6.8 Auto-Tuning Errors
Possible Solutions
1. Increase the value set in C1-01 [Acceleration Time 1].
2. Disconnect the machine from the motor and do Rotational
Auto-Tuning again.
• 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 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 Yaskawa 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 Yaskawa or your nearest sales
representative.
Possible Solutions
Correctly set the rated current indicated on the motor nameplate and
do Auto-Tuning again.
Examine and repair motor wiring.
Possible Solutions
1. Make sure that the input motor nameplate data is correct.
2. Do Auto-Tuning again and correctly set the motor nameplate
data.
Possible Solutions
Do Stationary Auto-Tuning again.
Note:
If the drive detects Er-25 after you do Stationary Auto-Tuning,
it is possible that the motor cannot use high frequency injection.
For more information, contact Yaskawa or your nearest sales
representative.
