5.5 Auto-Tuning Fault Detection
Digital Operator 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 during Rotational Auto-Tuning
was too high.
Digital Operator Display
Er-10
Cause
The encoder signal lines are not properly
connected to the drive.
Motor and PG direction are opposite.
The load pulled the motor in the opposite
direction of the speed reference and the
torque exceeded 100%.
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).
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-14
Cause
The motor speed exceeded twice the
amplitude of speed reference during Inertia
Tuning.
Digital Operator Display
Er-15
Cause
The output torque reached the torque limit
set in L7-01 through L7-04 during Inertia
Tuning.

Acceleration Error
• Increase the acceleration time (C1-01).
• Check if it is possible to disconnect the machine from the motor.
• Check the settings of parameters L7-01 and L7-02.
• 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 Direction Error
Check and correct wiring to the PG encoder.
Check the motor speed monitor U1-05 while turning the motor manually in forward direction. If the sign
displayed is negative, change the setting of parameter F1-05.
Uncouple the motor from the load and repeat Auto-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 the motor wiring for a short between motor lines.
• If a magnetic contactor is used between motors, make sure it is closed.
• Replace either 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 perform Auto-Tuning.
Replace either 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.
• Double check the motor rated current value that was entered to T1-04 for Auto-Tuning.
• Check the motor rated current value written on the motor nameplate and enter the correct value.
Motor Speed Error 2
Reduce the ASR gain set to C5-01.
Torque Saturation Error
• Increase the torque limits in L7-01 through L7-04 within reasonable limits.
• Reduce the test signal amplitude in T3-01 and repeat the tuning. If necessary, reduce the test signal
frequency (T3-02) and repeat the tuning.
