Warning message  Possible causes  To correct or avoid errors  Interrupts in
S7T Config* 
0020  Restart to apply 
parameter changes 
You have changed a 
parameter which is not applied 
directly 
To apply the parameter changes, 
you need to lock and reinitialize 
the object (MC_Reset with 
Restart
= TRUE)

0021  Dynamic values are 
being limited 
The dynamic values of the 
command (velocity, 
acceleration, delay or starting 
torque) are being limited, 
because they are out of 
configured limits. 
Check why the setpoint values are 
too high: configured max. values; 
mean velocity setpoint interface; 
encoder connection; mechanical 
configuration.

8001  Fatal internal error  Faulty / inconsistent project / 
software; can not be 
influenced by the user. 
Check the consistency of your 
project data. Compile the data 
again, then download all data to 
the module. Evaluate the error 
code in the alarm view of 
S7T Config and inform the 
Siemens Hotline.

8002 Internal fault  •  Version conflict 
•  Firmware error 
•  Inconsistent software 
Check consistency of your project 
data. Compile the data again, 
then download all data to the 
module. Evaluate the alarm view 
of S7T Config and inform the 
Siemens Hotline.

8003 Fatal configuration 
error 
Faulty axis configuration data. 
A hardware driver, or the 
device it addresses, may not 
be available 
•  Check the plausibility of 
changed parameters. 
(Example: Spindle pitch is 
0; 
Homing with absolute value 
encoder above zero mark is 
not possible). 
•  Check the connected devices 
and their configuration in 
HW Config. 
•  Verify that the telegram used 
is compatible with the object. 
•  Reload the technology to the 
PLC. 
20004, 20006 
8004  Configuration error  The configuration of a 
technological object is 
incomplete or faulty. 
Check the plausibility of changed 
parameters. Evaluate the detailed 
information in the alarm view of 
S7T Config.
