Fast-switching valves of the CMSX
defective
Send the device to the Festo repair
service
Mechanical connection between
CMSX and drive defective
Restore mechanical connection

tighten coupling, if necessary;
replace defective coupling
Failure of the compressed air
supply or unstable compressed air
supply
Establish compressed air supply;
minimise pressure fluctuations

The process valve does
not take on the correct
position if there is an
operating voltage failure.

The device does not react
to setpoint value
specifications.
Compressed air supply is lacking
Establish compressed air supply
Display shows the Sensor Error

The semi-rotary drive runs
to an end position, even
though another setpoint
value is specified.
The operating voltage supply is
outside the permissible range or
switched off. The fast-switching
valves take on the neutral position
