Number Cause Solution
F01044 Fault loading the data from
the memory card
 Replace the memory card of the CU.
F01105 Insufficient memory  Reduce the number of data records.
F01122 Frequency at the probe
input too high
 Reduce the frequency of the pulses at the measuring
input.
F01205 Time slice overflow  Contact Technical Support.
F01250 CU hardware fault  Replace the CU.
F01512 No scaling An attempt has been made to establish a conversion
factor for scaling which is not present.
 Apply scaling or check the transfer value.
F01662 CU hardware fault
1. Switch the CU off and on again.
2. Update the firmware.
3. Contact Technical Support.

Setpoint timeout: p2040 ≠ 0
ms and one of the following
causes:
● The bus connection is
interrupted
● The MODBUS master
is switched off
● Communications error
(CRC, parity bit, logical
error)
1. Establish the bus connection and switch on the
communication partners.
2. Possibly adapt p2040.
3. Set the PROFIBUS master to RUN.
F03505 Analog input, wire break
1. Check the connection with the signal source for
interruptions.
2. Check the level of the signal which is fed in.
The input current measured by the analog input can be
read in r0752.
F06310 Supply voltage (p0210)
incorrectly parameterized
1. Check the supply voltage and change the parameter
(p0210), if necessary.
2. Check the line voltage.
F07011 Motor overtemperature
1. Reduce the motor load.
2. Check the ambient temperature and the motor
ventilation.
3. Check the wiring and the connection of the sensor.
F07016 Motor temperature sensor
fault
1. Check that the sensor is correctly connected.
2. Check the parameter assignment (p0601).
3. Switch off the temperature sensor error (p0607 = 0).
F07086
F07088
Switching over units:
Parameter limit violation
 Check the adapted parameter value and correct it, if
necessary.
F07320 Automatic restart aborted
1. Increase the number of restart attempts (p1211). The
actual number of start attempts is shown in r1214.
2. Increase the waiting time in p1212 or the monitoring
time in p1213.
3. Apply the ON command (p0840).
4. Increase the monitoring time of the power unit or
disable the monitoring time (p0857).
5. Reduce the waiting time for resetting the fault
counter p1213[1] so that fewer faults are registered
in the time interval.
