Error message  Possible causes  To correct or avoid errors  Interrupts in
S7T Config* 
8045 Illegal command with 
current status 
•  A command of higher 
priority is busy (e.g. 
MC_Stop). 
•  The technology object is 
disabled or not ready. 
•  Received measurement 
command when homing
Acknowledge all queued errors of 
the technology object. 
Wait for the initialization of the 
technology object (after restart). 
Enable the technology object. 
Disable MC_Stop. 
Do not start any measuring 
commands in the homing phase. 
30006, 30009 
8047  Can not acknowledge 
this error 
It is not possible to reset the 
error with FB MC_Reset. 
Examples: 
•  An axis has been brought 
to standstill, and the error 
causing this can not be 
acknowledged. 
•  Further errors occur in the 
acknowledgment or restart 
phase.
Eliminate all causes of error and 
retry to acknowledge. Please note 
that you must acknowledge 
particular errors by cycling power.
30007 
8048  Unable to restart  The object is busy or a queued 
error prevents restart. 
Eliminate and acknowledge all 
queued errors and disable the 
object. 
20012 
8049 Illegal object 
combination 
Faulty combination of 
technology objects. Examples: 
•  Axis_2 was set as leading 
synchronization axis for 
Axis_1, and Axis_1 was 
set as leading axis for 
Axis_2. 
•  All synchronized drives are 
processed at different run 
levels. 
•  Set a definite leading / 
following axis combination. 
•  Assign the leading / following 
axes to the same run level 
(usually the interpolator 
cycle). 
20007 
804A  The required object 
interconnection is 
missing 
No allowances have been 
made in the application 
program for relevant 
combinations of leading / 
following axes and cam disks. 
Set the required leading axes and 
cam disks in the "Configuration" 
section of the synchronization 
object of the following axis. 
30008 
8087  Illegal cam position  At least one output cam 
position is invalid. The output 
cam was moved beyond the 
limits of the operating range. 
Check the output cam positions. 
Reduce the current delay / 
derivative time.
