rameter value invalid

ence value change unsuccessful

SINAMICS G120C converter
Operating Instructions, 07/2015, FW V4.7 SP3, A5E34263257B AC
Remedy
Switch CU off and on again, upgrade firmware, or contact technical sup-
port.
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 sup-
port.
Switch CU off and on again, upgrade firmware, or contact technical sup-
port.
Replace Power Module or contact technical support.
Remedy
1. Switch off the converter power supply and switch it on again.
2. After this fault, the converter powers up with the factory settings.
3. Recommission the converter.
Explanation: The parameter assignments on the memory card were made
with a different type of module (Article No.).
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.
Check the connection to the signal source for interrupts.
Check the level of the signal supplied.
The input current measured by the analog input can be read out in r0752.
Check that the sensor is connected correctly.
