Cancel
The PLC axis control cannot be aborted by means of parameter "Start", but only by means of
the axial interface signals (e.g. delete distancetogo). The axial interface also returns status
signals of the axis that may need to be evaluated (e.g. exact stop, traverse command).
Axis disable
With the axis disabled, an axis controlled via PLC axis control will not move. Only a
simulated actual value is generated. (Behavior as with NC programming).
Fault detection
If a PLC axis control could not be executed, this is indicated by the error signal
(V390x 3000.1 or V390x 3000.0) with 'logical 1'. The cause of the error is coded as an error
number.
