Remedy
Replace CU.
Switch off CU and switch 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: The parameter assignments on the memory card were cre-
ated with a different type of module (Article no.).
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 in-
volved can be calculated in the per unit notation (p0304, p0305, p0310,
p0596, p2000, p2001, p2002, p2003, r2004).
Save parameters (p0971).
Switch CU off and on again.
Replace memory card or CU.
Insert a memory card or deactivate the warning A01101.
Activate message for a memory card that is not inserted
(Page 249)
Reduce number of data sets.
Reduce the frequency of the pulses at the probe input.
Contact technical support.
Replace CU.
Create scaling or check transfer value.
Carry out maintenance and reset the maintenance interval (p0651).
Select the STO safety function and then deselect again.
Carry out an acceptance test and create test certificate.
Switch off the Control Unit and switch on again.
Cause: The inverter should be reset to the factory setting. However, it is
not permissible to reset the safety functions as the safety functions are
currently enabled.
Remedy with operator panel:
p0010 = 30 Parameter reset
p9761 = ... Enter password for the safety functions.
p0970 = 5 Reset start safety parameter.
The inverter sets p0970 = 5 once it has reset the pa-
rameters.
Then reset the inverter to the factory setting again.
