6.7 Auto-Tuning Fault Detection
Digital Operator Display
Er-08
Cause
Motor data entered during Auto-Tuning
was incorrect.
Results from Auto-Tuning are outside the
parameter setting range or the tuning
process took too long.
The load was too high during rotational
Auto-tuning.
Digital Operator Display
Er-09
Cause
The motor did not accelerate for the
specified acceleration time.
The load was too high during Rotational
Auto-Tuning.
Digital Operator Display
Er-11
Cause
Torque reference is too high.
Digital Operator Display
Er-12
Cause
One of the motor phases is missing:
(U/T1, V/T2, W/T3).
The current exceeded the current rating of
the drive.
The current is too low.
Attempted Auto-Tuning without motor
connected to the drive.
Current detection signal error.
Digital Operator Display
Er-13
Cause
Drive was unable to complete tuning for
leakage inductance within 300 seconds.
Digital Operator Display
Er-17
Cause
Drive is prohibited from rotating the motor
in reverse while attempting to perform
Inertia Tuning.

Rated Slip Error
• Make sure the data entered to the T1 parameters match the information written on the motor nameplate.
• Restart Auto-Tuning and enter the correct information.
• Check and correct faulty motor wiring.
• Perform Rotational Auto-Tuning.
• Disconnect the motor from machine and restart Auto-Tuning. If motor and load cannot be uncoupled make
sure the load is lower than 30%.
• If a mechanical brake is installed, make sure it is fully lifted during tuning.
Acceleration Error
• Increase the acceleration time (C1-01).
• Disconnect the machine from the motor if possible.
• Disconnect the motor from machine and restart Auto-Tuning. If motor and load cannot be uncoupled make
sure the load is lower than 30%.
• If a mechanical brake is installed, make sure it is fully lifted during tuning.
Motor Speed Fault
• Increase the acceleration time (C1-01).
• Disconnect the machine from the motor if possible.
Current Detection Error
Check motor wiring and correct any problems.
• Check motor wiring for a short between motor lines.
• Close any magnetic contactors used between motors.
• Replace the control board or the entire drive. For instructions on replacing the control board, contact
Yaskawa or your nearest sales representative.
Connect the motor and restart Auto-Tuning.
Replace the control board or the entire drive. For instructions on replacing the control board, contact Yaskawa
or your nearest sales representative.
Leakage Inductance Error
• Check all wiring and correct any mistakes.
• Check the motor rated current value written on the motor nameplate and enter the correct value to T1-04.
Reverse Prohibited Error
• Inertia Auto-Tuning cannot be performed if the drive is restricted from rotating in reverse.
• Assuming it is acceptable for the application to rotate in reverse, set b1-04 to 0 and then perform Inertia
Tuning.
