No. Name
119 Temperature 7798785 OH: Heatsink overtemperature
The heatsink temperature is higher than the
fixed limit temperature (90 ° C).
The ambient temperature of the controller may
be too high or the fan or its ventilation slots may
be dirty.
1: Error -
pulse inhibit
("Fault")
Check control cabinet temperature.
Clean air filter of control cabinet
Clean controller.
If required, clean or replace the fan
Provide for sufficient cooling of the
device.
119 Temperature 7798834 OC5: Ixt overload
The Ixt overload check has tripped due to
1.) wrong dimensioning of the device with
regard to its motor load or
2.) non-compliance with the load cycles
C00604 Regarding 1.) Check and, if required,
correct the dimensioning between the
device and motor load with regard to
technical data
Regarding 2.) Reduce load cycles of the
motor.
Observe load cycles according to the
documentation.

8060942 OU: DC-bus overvoltage
The device has detected an overvoltage in the DC
bus and an earth fault on the motor side. In order
to protect the device hardware, the inverter
control is switched off.
Depending on the configuration of the auto-
start lock function, C00142 serves to set that, if
the this error has been tripped, the controller
only starts after the controller inhibit is
switched.
If this error message remains active longer than
the time set in C00601 , a "Fault" is tripped.
2: Trouble Reduction of the load in generator
mode.
Use of a brake resistor
Use of a regenerative power supply
module.
Layout of a DC-bus connection.
Remove earth fault on the motor side.

8060943 LU: DC-bus undervoltage
The device has detected an undervoltage in the
DC bus. The inverter control is switched off since
the drive characteristics of the motor control
cannot be ensured anymore due to the DC-bus
undervoltage. The configuration of the auto-
start lock function C00142 serves to set that,
after this error has tripped, the controller only
starts after the controller inhibit is switched.
2: Trouble Switch on the mains supply or ensure
sufficient supply via DC bus.
Adapt C00142 , if required

8060944 OC1: Power section - short circuit
The device has detected a short circuit of the
motor phases. In order to protect the device
electronics, the inverter control is switched off.
Mostly, faulty motor connections are the reason.
If the device is dimensioned inappropriately with
regard to the motor load and if the current
limitation in the current controller is
misadjusted (I
max
controller), this error message
may occur as well.

current limits
1: Error -
pulse inhibit
("Fault")
Check of the motor connections and
the corresponding plug connector at
the device.
Compliance with the permissible
combinations of device and motor
power.
Do not set the dynamics of the current
limitation controller too high.
