Cause
Phase loss is occurring. (U/T1, V/T2,
W/T3)
The current exceeded the current rating
of the drive.
The output current is too low.
Attempted Auto-Tuning without motor
connected to the drive.
A current detection signal error
occurred.
Cause
The value that was input for the motor
rated current is incorrect.
Drive was unable to complete tuning for
leakage inductance within 300 seconds.
Cause
The motor speed exceeded twice the
amplitude of speed reference during
Inertia Tuning.
Cause
During Inertia Tuning, the output torque
exceeded the value set in L7-01 to L7-04
[Torue Limit ].
Cause
The inertia identified by the drive was
abnormally small or abnormally large
during Inertia Tuning (10% or less, or
50000% or more).
Cause
b1-04 = 1 [Reverse Operation Selection
= Reverse disabled] has been set.
Note:
Inertia Tuning cannot be performed
if the drive is prohibited from
rotating the motor in reverse.
Cause
The result of the induced voltage tuning
was outside the allowable range.
Cause
The Auto-Tuning results of the PM
motor inductance were outside the
allowable range.

Possible Solution
Check and correct faulty 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 board or the entire drive. For more
information on replacing the control board,
contact Yaskawa or your nearest sales
representative.
Connect the motor and restart Auto-Tuning.
Replace the board or the entire drive. For more
information on replacing the control board, contact
Yaskawa or your nearest sales representative.
Possible Solution
Correctly set the rated current indicated on the
motor nameplate and perform Auto-Tuning again.
Check and correct faulty motor wiring.
Possible Solution
Reduce the value set in C5-01 [ASR Proportional
Gain 1].
Possible Solution
• Increase the value set in L7-01 to L7-04 [Torque
Limit] as much as possible.
• Reduce the values set for the frequency and
amplitude of the test signals used when carrying
out inertia tuning. First, reduce the test signal
amplitude, and then perform Inertia Tuning. If
the error persists, reduce the test signal
frequency and perform Inertia Tuning again.
Possible Solution
• Reduce the values set for the frequency and
amplitude of the test signals used when carrying
out inertia tuning. First, reduce the test signal
amplitude, and then perform Inertia Tuning. If
the error persists, reduce the test signal
frequency and perform Inertia Tuning again.
• Correctly set the motor inertia according to the
motor, and then perform Inertia Tuning again.
Possible Solution
1. Check that the target machine has reverse
enabled.
2. Set b1-04 = 0 [Reverse enabled].
3. Perform Inertia Tuning again.
Possible Solution
1. Make sure the input motor nameplate data is
correct.
2. Perform Auto-Tuning again and correctly set
the data that appears on the motor nameplate.
Possible Solution
1. Make sure the input motor nameplate data is
correct.
2. Perform Auto-Tuning again and correctly set
the data that appears on the motor nameplate.
