Diagnostics & error management
Error messages of the operating system
oC1: Power section - short circuit [xx.0123.00016]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
The device has recognised a short circuit of the motor
phases. To protect the device electronics, the inverter
control is switched off.
• Mostly, incorrectly executed motor connections are
the cause.
• If the device is inappropriately dimensioned with
regard to the motor load and the current limitation in
the controller (Imax controller) is set incorrectly, this
error message may also occur.

oC2: Power section - earth fault [xx.0123.00017]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
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.
• If motor filters with additional terminals for +UG and
–UG and devices greater or equal 3 kW are used, the
earth fault detection may be triggered due to leakage
currents to +UG and –UG.
• A cause can also be the use of shielded motor cables
longer than 50 m.
oC10: Maximum current reached [xx.0123.00030]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
The device displays that the maximum current has been
reached.
oC17: Clamp sets pulse inhibit [xx.0123.00031]
Response (Lenze setting printed in bold)
0: No Reaction
Cause
Due to a short overcurrent, the inverter was switched off
for a short time (clamp disconnection).

4: WarningLocked 5: Warning 6: Information
Remedy
• Check motor connections and the corresponding plug
connector on the device.
• Only use permissible combinations of device power
and motor power.
• Do not set the dynamics of the current limitation
controller too high.

Remedy
• Check motor connections and the corresponding plug
connector on the device.
• Use motor filters, cable lengths, and cable types
recommended by Lenze.
• If motor filters with additional terminals for +UG and
–UG and devices greater or equal 3 kW are used:
– Up to version V05.00.00:
(C00602) to "0: No Reaction".
– From version V05.01.00:
detection during operation by setting a filter time
(C01770) of 250 ms.
• If motor cables longer than 50 m are used:
– From version V05.01.00:
earth fault detection during operation (C01770).

Remedy
• Check and, if required, correct dimensioning of the
load with regard to the installed device power.
• Check the maximum current settings in
(Imax in motor mode) and
mode).

Remedy
• 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.
