Signals From Axis/Spindle (Db31 - Siemens SINUMERIK 840Di Function Manual

Detailed Description
2.15 Spindles (S1)
DB31, ...
DBX30.1 Spindle start, clockwise rotation
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.1 (spindle start, clockwise)
edge change (corresponds to M3 spindle direction of rotation, clockwise for the master spindle)
0 → 1
Application With the positive edge of the starting signal "spindle start clockwise", the contents of the setting
example(s) data:
SD43200 $SA_SPIND_S
are read and become effective.
Corresponding to .... DB31, ... DBX18.7 (setpoint direction of rotation, counter-clockwise)
DB31, ... DBX18.6 (setpoint direction of rotation, clockwise)
DB31, ... DBX17.6 (invert M3/M4)
DB31, ...
DBX30.0 Spindle stop
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.0 (spindle stop)
edge change (corresponds to M5 spindle stop for master spindle).
0 → 1
Application A spindle stop is executed if the interface signal:
example(s) DB31, ... DBX61.4 (axis/spindle stationary) = 1
is signaled.
Corresponding to .... DB31, ... DBX17.6 (axis/spindle stationary)

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.
