Message
32
Target force outside the force limits
F1 (W)
R
Note
Message can be parameterised alternatively as a warning (W) or error (F1).
Cause
Target force outside the set force limits.
Measure
Correct target force or force limit.
Cause
The target force is larger than the maximum force that can be reached (the
maximum attainable target force determined by the CMAX may deviate from the
theoretical value calculated by the FCT).
Measure
Correct target force, increase supply pressure, reduce moving load in vertical
structure, use larger drive.
33
Target position outside the software or hardware end positions
F1 (W)
R
Note
Message can be parameterised alternatively as an error (F1) or warning (W).
Cause
Target position is outside the set software end positions.
Measure
Check and correct target position, software end positions and project zero
point.
Cause
Target position is outside the reachable hardware end positions.
Measure
Check and correct target position and project zero point.
34
Setpoint value in tracking mode outside the limit values
W (F1)
F (R)
Note
Message can be parameterised alternatively as a warning (W) or error (F1).
Cause
Setpoint position is outside the set software end positions.
Measure
Check and correct setpoint position, software end positions and project zero
point.
Cause
Setpoint position is outside the reachable hardware end positions.
Measure
Check and correct setpoint position and project zero point.
35
Software end position passed
W (F1)
F (R)
Note
The actual position has exceeded a software end position with active position
control, whereby a tolerance of 2 mm has been taken into account.
Message can be parameterised alternatively as a warning (W) or error (F1).
Cause
The drive was pushed out of the valid range by an external force.
Measure
Prevent external force, if possible.
Cause
Controllers which are not optimally set can lead to considerable overshooting.
Measure
Optimize controller, check parameterisation, perform identification again.
36
Software end position reached during force control
F1
R
Note
The actual position has exceeded a software end position with active force con
trol. A tolerance of 2 mm has been taken into account here.
Cause
No workpiece.
Measure
Check workpiece; check workpiece position.
Use record sequencing for return travel or stop.
Cause
Software end positions can be reached in the desired sequence.
Measure
Correct software end positions.
