Boundary conditions
Premature block change
A premature block change is not possible in the following cases:
● Oscillating axis
During oscillation with partial infeed, the block-specific oscillation motion must remain active
until the axis with partial infeed has reached its final position.
● Handwheel
For handwheel input, the last set end-of-motion criterion applies.
Changing the axis state
The axis for which a block change occurred within the braking ramp can only be programmed
in the following block in the same axis state.
When the axis state changes, e.g. to POS followed by SPOS, the last programmed end-of-
motion criterion FINEA, COARSEA, IPOENDA is active. This also applies in the following cases:
● a positioning axis becomes a path axis
● if the program waits for the end of the positioning movement: WAITP, M30, end of the
technology cycle, preprocessing stop
● Velocity override is deactivated or activated
