PLC controls axis
Signal(s) updated: Cyclic
Axis is controlled by the PLC.
The reaction to interface signals is controlled by the PLC by means of the 2 stop bits, other
signals with deceleration action are ignored.
Axis is not controlled by the PLC.
DBX28.5, DBX28.6
Oscillation reversal active
Signal(s) updated: Cyclic
The deceleration period after external oscillation reversal (DB31, ...DBX28.0) is active
No deceleration after external oscillation reversal is active
Oscillation cannot start
Signal(s) updated: Cyclic
The oscillation axis cannot be started owing to incorrect programming. This status can occur
even when axis has already been traversed.
The oscillation movement can be started.
Error during oscillation movement
Signal(s) updated:
The oscillation movement has been aborted.
The oscillation movement is being executed correctly.
