No response (configurable)

• The event can only be reset after a blocking time. Setting parameters: 0x2D45:001 (P310.01)

Motor phase failure phase W

A failure of the motor phase W has been detected.

• Check wiring between inverter and motor.
• In case of a false tripping, adapt the settings for the motor phase failure detection. - 0x2D45:002 (P310.02) (Current threshold) - 0x2D45:003 (P310.03) (Voltage threshold)

No response (configurable)

• The event can only be reset after a blocking time. Setting parameters: 0x2D45:001 (P310.01)

Motor parameter identification fault

During the automatic identification of the motor, an error has occurred.

• Set motor data so that they comply with the data on the motor nameplate.
• Check wiring of the motor.

Fault

FMF Error

Configuration or runtime error

• Check configuration
• Check FMF error code 0x4050:002 to determine the error cause.

Fault

Cascading overload

Cascade function for pumps and fans The maximum frequency in 0x2916 (P211.00) has been reached and no free additional pump is available.

• Check configuration of the cascade function.
• Check drive sizing.

Warning

Warning - Brake resistor overload

The calculated thermal load of the brake resistor has reached the warning threshold set in 0x2550:008 (P707.08). The regenerative energy is too high.

• Check drive dimensioning.
• Check settings for the brake energy management. Note: The warning status is reset if the thermal load falls below the warning threshold of - 20 %.

Warning (configurable) Setting parameters: 0x2550:010 (P707.10)

Automatic start disabled

At mains connection, a start command was already available and the automatic start at power-up is set in 0x2838:002 (P203.02) to "Off [0]".

Deactivate starting command and reset error.

Fault

Load loss detected

In a running motor, the motor load (current) is monitored. When the motor load falls below the threshold value specified in Load loss detection: threshold (0x4006:001 (P710.01)) for the period of time specified in Load loss detection: delay time (0x4006:002 (P710.02)), load loss protection is triggered.

Check utilisation

No response (configurable) Setting parameters: 0x4006:003 (P710.03)

Motor overload

If the apparent motor current exceeds a defined threshold value 0x4007:002 for a certain amount of time 0x4007:001, heavy duty monitoring is triggered.

Check the motor load.

No response (configurable) Setting parameters: 0x4007:003

Maximum motor frequency reached

• The limitation of the maximum motor speed set in 0x6080 (P322.00) is active.
• The maximum output frequency of the inverter has been reached.
• Depending on the parameter setting of 0x2D44:001 (P350.01) (Overspeed monitoring: threshold), the speed limitation (0x6080 / Max. motor speed) may become active before speed monitoring.

Check application.

Warning

Manual mode disabled

Indicates the deactivation of the manual speed control.

Warning

Manual mode activated

Indicates the activation of the manual speed control.

Warning

Manual mode time-out

If "manual operation" is active, an error is generated in case the communication links get lost.

The error can be only be reset if the connection is restored or the control mode is changed to a different value than "manual operation".

Fault

Wrong password

A wrong password has been entered several times.

Wait until the blocking time has elapsed and then enter the correct password.

Warning

• The blocking time for entering a password is more than 10 seconds. (The blocking time is doubled every time an incorrect password is entered.)
• No password can be entered as long as the blocking time is active.

Brand protection - not compatible

Inverter is not compatible with the Controller/PLC (brand protection).

• The Controller has not written a deactivation password in the parameter yet.
• The deactivation password written by the Controller is incorrect.

Use corresponding (compatible) OEM components.

Warning

• No response from the inverter.
• The decision on whether the machine will be commissioned or not is made by the Controller.

Fatal Error

Error when reading the data from the control unit.

• Switch inverter off and on again.
• If the error occurs again, the manufacturer must be contacted, since the control unit or the device has to be replaced.

Fault

• Operation of the inverter is not possible.

Power unit fatal error

Error when reading the data from the power unit.

• Switch inverter off and on again.
• If the error occurs again, the manufacturer must be contacted, since the power unit or the device has to be replaced.

Fault

• Operation of the inverter is not possible.

Keypad full control active

If the "Keypad Full Control" control mode is active.

To exit the control mode, press the keypad key CTRL.

Warning

• Both the activity of controlling and the setpoint selection are carried out via the keypad.
