Remedy
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.
Check the following:
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
Reduce the motor load.
Check ambient temperature.
Check sensor's wiring and connection.
Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
Make sure that the sensor is connected correctly.
Check the parameterization (p0601).
Check the adapted parameter values and if required correct.
