Response (Lenze setting printed in bold)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
The device has recognised an earth fault at one of the
motor phases. To protect the device electronics, the in-
verter control is switched off.
• Mostly, incorrectly executed motor connections are
the cause.
• If motor filter, motor cable length, and cable type
(shielding capacity) are dimensioned incorrectly, this
error message may occur due to leakage currents to
PE.
• Check motor connections and the corresponding plug
connector on the device.
• Use motor filters, cable lengths, and cable types rec-
ommended by Lenze.
Response (Lenze setting printed in bold) Setting: C00579 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
The device has recognised that the maximum speed has
been reached.
• Limit setpoint selection to maximum values.
• Adjust set speed limitation ( C00909 ) and frequency
limitation ( C00910 ).
Response (Lenze setting printed in bold)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
The device has recognised that the maximally permissi-
ble motor speed has been reached.
• Limit setpoint selection to the maximally permissible
motor speed.
• If required, adapt set maximum motor speed
( C00965 ).

 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
During the identification of motor parameters, an error
has occurred.
Possible causes:
• Interrupted motor cable.
• Switched-off power section during the identification.
• Implausible start parameter settings.
• Check the motor connections and the corresponding
plug connector on the device and, if necessary, the
motor terminal box.
• Correct start parameters for the motor parameter
identification (motor nameplate data).
• Stable power supply of the device.

 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Too frequent and too long braking processes. Check drive dimensioning.
