Reduced Acceptance After Component Replacement And Firmware Change; If The Converter No Longer Responds - Siemens Sinamics CU240D-2 DP Operating Instructions Manual

9.4 Reduced acceptance after component replacement and firmware
change
After a component has been replaced or the firmware updated, a reduced acceptance test of
the safety functions must be performed.
Measure
Replacing the Control Unit.
Replacing the Power Module.
Replacing the motor with an iden-
tical pole pair number
Replace the gearbox with an iden-
tical ratio
Replacing safety-related I/O de-
vices (e.g. Emergency Stop
switch).
Inverter firmware update.

If the converter no longer responds

If the inverter no longer responds
For example, when loading an incorrect file from the memory card, the inverter can go into a
state where it can no longer respond to commands from the operator panel or from a higher-
level control system. In this case, you must reset the inverter to its factory setting and
recommission it. This inverter state is manifested in two different ways:
Case 1
● The motor is switched off.
● You cannot communicate with the inverter, either via the operator panel or other
interfaces.
● The LEDs flicker and after 3 minutes the inverter has still not powered up.
