Solution
3. Recommission the drive.
Set the value of the reference parameter not equal to 0.0 (p0304, p0305,

p0310, p0596, p2000, p2001, p2002, p2003, r2004).
Select the value of the reference parameter so that the parameters involved can

be calculated in the representation (p0304, p0305, p0310, p0596, p2000,
p2001, p2002, p2003, r2004).
Save the parameters (p0971).

Switch the CU off and on again.

 Replace the memory card of the CU.
Reduce the number of data records.

 Reduce the frequency of the pulses at the measuring input.
Contact Technical Support.

 Replace the CU.
An attempt has been made to establish a conversion factor for scaling which is not
present.
Apply scaling or check the transfer value.

 Switch the CU off and on again.
Update the firmware.

Contact Technical Support.

Establish the bus connection and switch on the communication partners.

 Possibly adapt p2040.
Set the PROFIBUS master to RUN.

Check the connection with the signal source for interruptions.

 Check the level of the signal which is fed in.
The input current measured by the analog input can be read in r0752.
 Check the supply voltage and change the parameter (p0210), if necessary.
Check the line voltage.

Reduce the motor load.

 Check the ambient temperature and the motor ventilation.
 Check the wiring and the connection of the sensor.
Check that the sensor is correctly connected.

Check the parameter assignment (p0601).

Switch off the temperature sensor error (p0607 = 0).

Check the adapted parameter value and correct it, if necessary.

Increase the number of restart attempts (p1211). The actual number of start

attempts is shown in r1214.
 Increase the waiting time in p1212 or the monitoring time in p1213.
Apply the ON command (p0840).

Increase the monitoring time of the power unit or disable the monitoring time

(p0857).
Reduce the waiting time for resetting the fault counter p1213[1] so that fewer

faults are registered in the time interval.
 Increase the search current (p1202).
