Digital Operator Display Error Name
Er-08 Rated Slip Error
Cause Possible Solutions
Motor data entered during Auto-Tuning
was incorrect.
• 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.
Results from Auto-Tuning are outside the
parameter setting range or the tuning
process took too long.
• Check and correct faulty motor wiring.
• Perform Rotational Auto-Tuning.
The load was too high during 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.
Digital Operator Display Error Name
Er-09 Acceleration Error
Cause Possible Solutions
The motor did not accelerate for the
specified acceleration time.
• Increase the acceleration time (C1-01).
• Disconnect the machine from the motor if possible.

Auto-Tuning.
• Disconnect the motor from machine and restart Auto-Tuning. If motor and load cannot be uncoupled make

Digital Operator Display Error Name
Er-11 Motor Speed Fault
Cause Possible Solutions
Torque reference is too high.
• Increase the acceleration time (C1-01).
• Disconnect the machine from the motor if possible.
Digital Operator Display Error Name
Er-12 Current Detection Error
Cause Possible Solutions
One of the motor phases is missing:
(U/T1, V/T2, W/T3).
Check motor wiring and correct any problems.
The current exceeded the current rating of
the drive.
• 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.
The current is too low.
Attempted Auto-Tuning without motor
connected to the drive.
Connect the motor and restart Auto-Tuning.
Current detection signal error.
Replace the control board or the entire drive. For instructions on replacing the control board, contact Yaskawa
or your nearest sales representative.
Digital Operator Display Error Name
Er-13 Leakage Inductance Error
Cause Possible Solutions
Drive was unable to complete tuning for
leakage inductance within 300 seconds.
• 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.
Digital Operator Display Error Name
Er-17 Reverse Prohibited Error
Cause Possible Solutions
Drive is prohibited from rotating the motor
in reverse while attempting to perform
Inertia Tuning.
• 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.
