 None : Fault  Trouble  TroubleQuickstop  Warning  WarningLocked  Information
Cause Remedy
The device has recognised an earth fault at one of the
motor phases. To protect the device electronics, the
inverter 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
recommended by Lenze.

 None : Fault  Trouble  TroubleQuickstop  Warning  WarningLocked  Information
Cause Remedy
The device displays that the maximum current has been
reached.
• Check and, if required, correct dimensioning of the
load with regard to the installed device power.
• Check the maximum current settings in C00022
(Imax in motor mode) and C00023
(Imax in generator
mode).

: None ; Fault  Trouble  TroubleQuickstop ; Warning  WarningLocked  Information
Cause Remedy
Due to a short overcurrent, the inverter was switched off
for a short time (clamp disconnection).
• Check and, if required, correct dimensioning of the
load with regard to the installed device power.
• Reduce the dynamics of the setpoint change or speed
control.
Response (Lenze setting printed in bold) Setting: C00579 (; Adjustable response)
: None ; Fault  Trouble  TroubleQuickstop ; Warning  WarningLocked  Information
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
) if necessary.
