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).
• Check if it is possible to disconnect the machine from the motor.
Torque limit when motoring is too low
(L7-01 and L7-02).
• Check the settings of parameters L7-01 and L7-02.
• Increase the setting.
The load during Rotational Auto-Tuning
was too high.
• 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-10 Motor Direction Error
Cause Possible Solutions
The encoder signal lines are not properly
connected to the drive.
Check and correct wiring to the PG encoder.
Motor and PG direction are opposite.
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.
The load pulled the motor in the opposite
direction of the speed reference and the
torque exceeded 100%.
Uncouple the motor from the load and repeat Auto-Tuning.
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.
Current exceeded the current rating of the
drive.
• 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.
The current is too low.
Attempted Auto-Tuning without motor
connected to the drive.
Connect the motor and perform Auto-Tuning.
Current detection signal error.
Replace either 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.
• 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.
Digital Operator Display Error Name
Er-14 Motor Speed Error 2
Cause Possible Solutions
The motor speed exceeded twice the
amplitude of speed reference during Inertia
Tuning.
Reduce the ASR gain set to C5-01.
Digital Operator Display Error Name
Er-15 Torque Saturation Error
Cause Possible Solutions
The output torque reached the torque limit
set in L7-01 through L7-04 during Inertia
Tuning.
• 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.
