Operating Instructions, 03/2012, FW V4.5, A5E02999804B AB
Remedy
Create scaling or check transfer value.
Switch CU off and on again, upgrade firmware, or contact technical
support.
Check or replace the Power Module.
CE
Replace Power Module or upgrade CU firmware.
Replace the Power Module.
Switch CU off and on again, upgrade firmware, or contact technical
support.
Switch CU off and on again, upgrade firmware, or contact technical
support.
Replace Power Module or contact technical support.
Remedy
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 converter.
Explanation: Parameterization on the memory card has been created with a
different type of module (order number, MLFB)
Check the module parameters and recommission if necessary.
Set the value of the reference parameter to a value other than 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).
Reduce the frequency of the pulses at the probe input.
Carry out the maintenance.
Explanation: A PROFIBUS master is attempting to establish a connection
with a faulty configuration telegram.
Check the bus configuration on the master and slave side.
The alarm is generated when p2040 ≠ 0 ms and one of the following causes
is present:
The bus connection is interrupted

The MODBUS master is switched off

Communications error (CRC, parity bit, logical error)

An excessively low value for the fieldbus monitoring time (p2040)
Explanation: The cyclic connection to PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master
with cyclic operation.
