NC/PLC Interface Signals (Z1)
2-126 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
DB31, ...
DBX30.1 Spindle start, clockwise rotation
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
DB31, ... DBX30.1 (spindle start, clockwise)
(corresponds to M3 spindle direction of rotation, clockwise for the master spindle)
Application
example(s)
With the positive edge of the starting signal "spindle start clockwise", the contents of the setting
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(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
DB31, ... DBX30.0 (spindle stop)
(corresponds to M5 spindle stop for master spindle).
Application
example(s)
A spindle stop is executed if the interface signal:
DB31, ... DBX61.4 (axis/spindle stationary) = 1
is signaled.
Corresponding to .... DB31, ... DBX17.6 (axis/spindle stationary)
2.15.2 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX60.0 Spindle/no axis
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The machine axis is operated in one of the following spindle modes:
• Control mode
• Oscillation mode
• Positioning mode
• Rigid tapping
• Synchronous mode
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.
