HOA Keypad 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.
HOA Keypad Display
Er-09
Cause
The motor did not accelerate for the specified
acceleration time.
Torque limit when motoring is too low
(L7-01 and L7-02)
The load was too high during Rotational Auto-
Tuning.
HOA Keypad Display
Er-11
Cause
Torque reference is too high.
HOA Keypad 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.
HOA Keypad Display
Er-13
Cause
Drive was unable to complete tuning for leakage
inductance within 300 seconds.

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.
• Check L7-01 and L7-02 settings.
• Increase the setting.
• 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.
