# ID 60250

Axis which is not referenced, exceeds velocity limit.
Description | When the axis is not referenced, max. permissible speed is limited to P-AXIS-00268 .
Response | Class | 6 | Stopping the axis, and aborting the NC program.
Solution | Class | 6 | Generally there are two possibilities to avoid this message: increase the value of P-AXIS-00268 so that the commanded velocity for the axis is less than P-AXIS-00268. or you command a velocity value for this axis that is smaller than P-AXIS-00268.

It’s necessary for both methods, to know the source of the commanded velocity value, to move a not referenced axis. If the message occurs because

homing is triggered, refer to the function description [FCT-M1// Homing] which describes which of the parameters P-AXIS-00218 or P-AXIS-00219 is used for the selected homing method. For the different homing modes, either one of the two or both parameters is taken into account and are therefore decisive for the comparison with P-AXIS-00268.

If a motion command is triggered, i.e. by NC program code or by a job from the PLC, the feeds specified there are decisive for comparison with P-AXIS-00268.

Parameter | %1: | Logical axis number [-]
