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

DB31, ...
DBX60.0 Spindle/no axis
Edge evaluation: yes
Signal state 1 or The machine axis is operated in one of the following spindle modes:
edge change
•
0 → 1
•
•
•
•
The interface signals to the axis (DB31, ... DBB12 - DBB15) and from the axis
(DB31, ... DBB74 - DBB81) are invalid.
The interface signals to the spindle (DB31, ... DBB16 - DBB19) and from the spindle
(DB31, ... DBB82 - DBB91) are valid.
Signal state 0 or The machine axis is operated as an axis
edge change
The interface signals to the axis (DB31, ... DBB12 - DBB15) and from the axis
1 → 0
(DB31, ... DBB74 - DBB81) are valid.
The interface signals to the spindle (DB31, ... DBB16 - DBB19) and from the spindle
(DB31, ... DBB82 - DBB91) are invalid.
Application If a machine axis operates alternatively as a spindle or rotary axis:
