Group 3 − Control error
CPX error group 103
(CPX-MMI: [Control error] )
No.
Message
Error level Reset type
30
Time-out: Target value not reached
F1
R
Note
The drive did not reach the target tolerance on time (MC monitoring). Record
chaining is cancelled. Can, for instance, occur during positioning or jogging on a
stop within the effective stroke.
Cause
Obstacle in the travel range (only position controller).
Measure
Remove obstacle or correct target position.
Cause
Compressed air not sufficient.
Measure
Check supply pressure, check tubing connection, configure message 50 as an
error; enable drive with closed clamping unit only when there is sufficient
supply pressure.
Cause
Very strong friction or irregular friction (only position controller).
Measure
Increase control amplification.
Cause
Mechanical play (only position controller)
Measure
Check installation: Load, stability, guides, check play, repeat identification.
Cause
System not optimally configured.
Measure
Check configuration (valve, payload, base load, mounting position, supply
pressure), increase time-out, increase tolerance.
Cause
Modified system behaviour (only position controller).
Measure
Repeat identification.
31
No movement after start
F1
R
Note
Time-out: The drive has moved less than 11 mm within the time-out period.
Cause
Pressure could not be built up.
Measure
Check supply pressure.
Cause
Drive jammed or sluggish.
Measure
Check guide and mechanical structure.
Cause
Working pressure insufficient to move the entire load.
Measure
Set sufficient working pressure and check configuration of the load.
Cause
Valve defective.
Measure
Check pressure build-up with trace; replace valve if defective.
Cause
Faulty tubing connection.
Measure
Check tubing connection.
Cause
Valves (additional pneumatic circuit) installed between the valve and cylinder are
closed.
Measure
Open valves.
