6.6 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.
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 ramp.
Torque limit when motoring is too low (L7-01 and
L7-02).
The load during Rotational Auto-Tuning 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.
Cause
Stator resistance tuning attempted to set a value to
E5-06 that is outside the allowable setting range.

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. Remember that the rope must be fully removed from the motor and the brake must be released to
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. Remember that the rope must be fully removed from the motor and the brake must be released to
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-09 Acceleration Error
Lengthen the acceleration ramp (C1-01).
• Check the settings of parameters L7-01 and L7-02.
• Increase the setting of L7-01 and L7-02.
• 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
• Lengthen the acceleration ramp set to C1-01 (i.e., increase the acceleration time.)
• 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.
• Make sure the motor contactor is closed during tuning.
• Replace either the control board or the entire drive. For instructions on replacing the control board, The current is too low. contact
Yaskawa or your nearest sales representative.
Connect the motor and perform Auto-Tuning.
