Err8: Optional Unit Error

    One of the optional devices (such as a communication device) is faulty.
    Solutions: Check the connection of the optional card(s). Refer to the relevant instructions and try to resolve the issue (Section 6.36).

Etn: Auto-tuning Error

    The capacity of the connected motor is 2 levels or more smaller than the inverter capacity.
    The connected motor is not a three-phase inductive motor.
    Tuning was performed while the motor was running.

    Solutions:
        Ensure a motor is connected.
        Ensure the motor is stopped.
        Perform auto-tuning again, and if the error persists, perform manual tuning.

Etn1 (F410): F410 Tuning Error

    Tuning could not be performed for the torque boost specified by F410.
    The capacity of the connected motor is 2 levels or more smaller than the inverter capacity.
    The connected motor is not a three-phase inductive motor.
    Tuning was performed without a motor connected.
    The cables connecting the inverter and the motor are too long (over 30m).
    Tuning was performed while the motor was running.

    Solutions:
        Ensure a motor is connected.
        Ensure the motor is stopped.
        Perform auto-tuning again, and if the error persists, perform manual tuning.

Etn2 (F412): F412 Tuning Error

    Tuning could not be performed for the leakage inductance specified by F412.
    Tuning could not be performed for the torque boost specified by F410.
    The capacity of the connected motor is 2 levels or more smaller than the inverter capacity.
    The connected motor is not a three-phase inductive motor.
    Tuning was performed without a motor connected.
    The cables connecting the inverter and the motor are too long (over 30m).
    Tuning was performed while the motor was running.

    Solutions:
        Ensure a motor is connected.
        Ensure the motor is stopped.
        Perform auto-tuning again, and if the error persists, perform manual tuning.

Etn3: Motor Constant Setting Error

    Some elements from the motor nameplate have been entered incorrectly:
        Base frequency (UL)
        Base frequency voltage (UU)
        Motor rated capacity (F405)
        Motor rated current (F406)
        Motor rated speed (F407)

    Solution: Ensure all elements from the motor nameplate are entered correctly.

EtyP: Inverter Type Error

    Has the circuit board (or the main circuit/driver circuit board) been replaced? Solution: If the board has been replaced, enter 6 for the tYP parameter.

E-10: Analog Input Terminal Overvoltage

    Overvoltage has been applied to the analog input. Solution: Apply voltage within the specified limits.
