Operating Instructions, 04/2018, FW V4.7 SP10, A5E31759476B AG
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 powered up 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 CU off and on again.
Replace memory card or CU.
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 components
● Reduce the sampling time of the free function blocks
Insert a memory card or deactivate alarm A01101.
Activate message for a memory card that is not inserted
(Page 372)
Reduce number of data sets.
Reduce the frequency of the pulses at the probe input.
Contact technical support.
Replace CU.
A function requested by the Control Unit is not supported by a DRIVE-CLiQ
component.
