Result of the movement test not clear F1 R
Cause Drive jammed.
Measure Check friction of the drive and guide.
Check pressure build-up with trace.
Cause Obstacle in the travel path
Measure Check travel path and software end positions.
Cause Working pressure insufficient to move the load.
Measure Set sufficient working pressure and check the load.
Cause Cylinder not correctly projected.
Measure Check size and correct.
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.

Identification failed F1 R
Cause Incorrect base load and/or payload parameterised or incorrect payload
transferred to parameter 2 (byte 5 ... 8 in commissioning mode).
Measure Check load and data.
Cause Too much mechanical play in the system.
Measure Check system structure.
Cause Constructional design not stable enough.
Measure Check system structure.
Cause Tubes used are too long.
Measure Move valve closer to the drive.
Cause Compressed air not sufficiently stable.
Measure Check compressed air supply.
17 Identification not yet executed W F
Cause Identification was not executed before record start and direct mode.
Measure Carry out identification.
18 Clamping unit was activated with operation enable W F
Cause Operation enable was granted (CCON.STOP = 1), although the clamping unit was
not yet released, or the clamping unit was closed without the operation enable
having been blocked beforehand (CCON.STOP=0).
Measure Remove operation enable.
Release clamping unit.
Correct the sequence when changing from operation enable and clamping
