Response (Lenze setting printed in bold)
 None  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 re-
commended by Lenze.

 None  Fault  Trouble  WarningLocked
Cause Remedy
The device has detected an error during the motor data
identification.
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.

 None  Fault  Trouble  WarningLocked
Cause Remedy
Too frequent and too long braking processes. Check drive dimensioning.
Response (Lenze setting printed in bold) Setting: C606 ( Adjustable response)
 None  Fault  Trouble  WarningLocked
Cause Remedy
Thermal overload of the motor. • Observe load requirements.
• Correct dimensioning if necessary.
• In case of VFCplus operation: Check Vmin boost
( C016 ).
 Set Vmin boost
Response (Lenze setting printed in bold) Setting: C598/1 ( Adjustable response)
 None  Fault  Trouble  WarningLocked
Cause Remedy
Open-circuit monitoring for analog input has tripped.
• Only if the analog input has been configured as a cur-
rent loop of 4 ... 20 ( C034/1 = 2).
• Check wiring of the analog X4/A1U input terminal for
open circuit.
• Check connection of the external 250-Ω load resistor
between the terminals A1U and GND.
• Check minimum current values of the signal sources.
