Alter reversal point
Signal(s) updated: Cyclic
The selected reversal point can be altered by manual traverse.
In conjunction with DB31, ...DBX28.0:
The position at which axis is braked after external oscillation reversal must be accepted as
new reversal point.
The selected reversal point cannot be altered by manual traverse.
In conjunction with DB31, ...DBX28.0:
No change to reversal point
DBX28.3
Stop at next reversal point
Signal(s) updated: Cyclic
The oscillation movement is interrupted at the next reversal point.
The oscillation movement continues after the next reversal point.
DBX28.6, DBX28.7
Stop along braking ramp
Signal(s) updated: Cyclic
The axis is decelerated along a ramp, the oscillation movement is interrupted.
The oscillation movement continues without interruption.
DBX28.5, DBX28.7
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.
