Digital Operator Display Error Name
Er-05 No-Load Current Error
Cause Possible Solutions
Motor data entered during Auto-Tuning was
incorrect. • 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.
Results from Auto-Tuning are outside the parameter
setting range or the tuning process took too long.
• 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.
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-08 Rated Slip Error
Cause Possible Solutions
Motor data entered during Auto-Tuning was
incorrect. • 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.
Drive-calculated values outside parameter setting
range or the tuning process took too long.
• 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.
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-09 Acceleration Error
Cause Possible Solutions
The motor did not accelerate for the specified
acceleration ramp.
Lengthen the acceleration ramp (C1-01).
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 of L7-01 and L7-02.
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-11 Motor Speed Fault
Cause Possible Solutions
Torque reference is too high.
• Lengthen the acceleration ramp set to C1-01 (i.e., increase the acceleration time.)
• 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.
• 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.
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.
Cause Possible Solutions
Stator resistance tuning attempted to set a value to
E5-06 that is outside the allowable setting range.
Double-check the data entered to the T2- parameters, and perform Auto-Tuning again.
