OC1: Power section - short circuit [xx.0123.00016]
OC2: Power section - earth fault [xx.0123.00017]

Response (Lenze setting printed in bold)
0: No Reaction : 1: Fault 2: Trouble 4: WarningLocked
Cause Remedy
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.
Motor control: Defining current limits
• 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.
Response (Lenze setting printed in bold)
0: No Reaction : 1: Fault 2: Trouble 4: WarningLocked
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.

4: 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 ) if necessary.

4: 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.
