A01028
Configuration error
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.
A01590
Motor maintenance interval
lapsed
Carry out maintenance and reset the maintenance interval (p0651).
A01900
PROFIBUS: Configuration
telegram faulty
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.
A01920
PROFIBUS: Cyclic connection
interrupt
Explanation: The cyclic connection to PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master
with cyclic operation.

Temperature sensor fault
Check that the sensor is connected correctly.
A05000
A05001
Power Module overtemperature 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?
A07012
