Signals to axis/spindle (DB31, ...)

VDI input signals
The PLC user program uses the following signals to control the oscillation process.
DB31, ...
DBX28.0
Edge evaluation: Yes
Signal state 1 or edge
change 0 → 1
Signal state 0 or edge
change 1 → 0
DB31, ...
DBX28.3
Edge evaluation: No
Signal state 1 or edge
change 0 → 1
Signal state 0 or edge
change 1 → 0
DB31, ...
DBX28.4
Edge evaluation: No

External oscillation reversal
Signal(s) updated: Cyclic
Brake oscillation motion and move oscillation axis in the opposite direction.
Continue oscillation without interruption
Set reversal point
Signal(s) updated: Cyclic
Reversal point 2
Reversal point 1
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
