Remedy
Replacing the Control Unit.
Switch the Control Unit off and on again.
Upgrade firmware or contact technical support.
1. Switch the module off and on again.
2. After this fault has been output, the module is booted with the factory
settings.
3. Recommission the inverter.
Explanation: Parameterization on the memory card has been created with
a different type of module (Article number, MLFB).
Check the module parameters and recommission if necessary.
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 per unit notation (p0304, p0305, p0310, p0596,
p2000, p2001, p2002, p2003, r2004).
Save parameters (p0971).
Switch the Control Unit off and on again.
Replace the memory card or the Control Unit.
The maximum computing power of the Control Unit was exceeded. The
following measures reduce the load on the Control Unit:
● Use only one data record (CDS and DDS)
● Only use the safety features of the basic functions
● Deactivate the technology controller
● Use the simple ramp-function generator rather than the extended ramp-
function generator
● Do not use any free function blocks
● Reduce the sampling time of the free function blocks
Reduce number of data sets.
Reduce the frequency of the pulses at the probe input.
Contact technical support.
Replacing the Control Unit.
Create scaling or check transfer value.
Select the STO safety function and then deselect again.
Converter with the CU240B-2 and CU240E-2 Control Units
