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.
The load was too high during 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.
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.
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.
The load was too high during 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.
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).
•
Disconnect the machine from the motor if possible.
Torque limit when motoring is too low
(L7-01 and L7-02).
• Check L7-01 and L7-02 settings.
• Increase the setting.
The load was too high during 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.
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 direction and PG direction are
opposite.
Check the motor speed monitor U1-05 while manually turning the motor forward. 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 restart Auto-Tuning.
Digital Operator Display Error Name
Er-11 Motor Speed Error
Cause Possible Solutions
Torque reference is too high.
• Increase the acceleration time 1 (C1-01).
•
Disconnect the machine from the motor if possible.
