8074  The leading axis is 
not configured for 
synchronous 
operation 
•  In the configuration of 
the following axis, the 
axis connected at the 
"Master" terminal was 
not defined as leading 
axis. 
• 
The leading axis is not 
enabled (applies only 
for the external 
encoder). 
•  The leading axis is 
operated with velocity 
control. 
Adjust the configuration of the 
following axis or use the 
configured leading axes. 
Operate the leading axis in 
position-controlled mode or 
enable it.

8077 Deactivation of 
synchronous 
operation aborted 
Deactivation of 
synchronous operation 
was rejected, because the 
current synchronous 
operation type (gear/cam 
gear) does not agree with 
the deactivation type. 
Deactivate camming with 
MC_CamOut and gearing 
with MC_GearOut, or use 
global instructions (MC_Halt, 
MC_Stop, ...)

8078 Superimposing 
synchronism is not 
possible 
Superimposing 
synchronism was set for 
the axis in the experts list.

experts list 
8082 Illegal Zero value in 
parameter 
A command was passed 
alongside with a 
Zero 
parameter. This value 
must always be unequal 
to 
Zero. 
Check the transferred 
parameters, preset values 
and, in particular, the dynamic 
and limit values. (e.g. max. 
velocity, or acceleration for 
positioning)

8085 Illegal limit switch 
parameters 
Implausible position 
values for the SW limit 
switch. One of the values 
violates the range, or the 
start value exceeds the 
end value. The latter may 
occur if the order is 
neglected when the 
parameters are changed. 
Adjust the setting of the SW 
limit switch. After the first 
change of the position, the 
position value of the positive 
switch must be higher than 
that of the negative switch.
