6.7 Auto-Tuning Fault Detection
Digital Operator Display
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.
Motor cable or cable connection faulty.
Digital Operator Display
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 during Rotational Auto-tuning was too
high.
Digital Operator Display
Cause
Motor data entered during Auto-Tuning was
incorrect.
Drive-calculated values outside parameter setting
range or the tuning process took too long.
The load during rotational Auto-tuning was too high.
Digital Operator Display
Cause
The motor did not accelerate for the specified
acceleration time.
The load during Rotational Auto-Tuning for V/f
control (T1-01 = 3) was too high.
Digital Operator Display
Cause
Torque reference is too high.
Digital Operator Display
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.

Er-04 Line-to-Line Resistance 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.
Er-05 No-Load Current 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.
Er-08 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 for V/f control (T1-01 = 3).
• 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.
Er-09 Acceleration Error
• Increase the acceleration time (C1-01).
• Check if it is possible to disconnect the machine from the motor.
• 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.
Er-11 Motor Speed Fault
• Increase the acceleration time (C1-01).
• Disconnect the machine from the motor, if possible.
Er-12 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.
