DB31, ...
DBX84.7 Active spindle mode: Control mode
Edge evaluation: yes Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The spindle is in control mode with the following functions:
• Spindle direction of rotation specification M3/M4 or spindle stop M5
• M41...M45, or automatic gear stage change M40
Corresponding to ... DB31, ... DBX84.6 (spindle mode oscillation mode)
DB31, ... DBX84.5 (spindle mode positioning mode)
DB31, ...
DBX85.5 Spindle in position
Edge evaluation: yes Signal(s) updated: Cyclic
The interface signal is processed exclusively with the function spindle positioning. This includes:
• SPOS, SPOSA and M19 in the part program
• SPOS and M19 in synchronized actions
• Spindle positioning, using FC18
• Spindle positioning via PLC interface (DB31,...DBX30.4)
Signal state 1 or
edge change
0 → 1
Precondition for the output of the DB31, ... DBX85.5 signal (spindle in position) is reaching the
"Exact stop fine".
DB31, ... DBX60.7 (exact stop fine) = 1
Additionally, the last programmed spindle position must have been reached on the setpoint side.
If the spindle is already at the programmed position after a positioning, then signal DB31,... DBX85.5
(spindle in position) is set.
Signal state 0 or
edge change
1 → 0
When signal DB31, ... DBX60.7 is withdrawn (exact stop fine), then signal DB31,...DBX85.5
(spindle in position) is also always reset.
Application
example(s)
Spindle in position for the tool change
If the machine operator interrupts the tool change cycle (e.g. with NC stop, NC stop axis plus
spindle, mode group stop etc.), then NC/PLC interface signal DB31,...DBX85.5 can be used to
query that the position has been reached with which the spindle should enter the tool changer.
Corresponding to ... DB31, ... DBX60.7 (Exact stop fine)
DB31, ...
DBB86 M function for spindle
Edge evaluation: yes Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
From the NCK one of the following M functions: M3, M4, M5, M70 is output to the PLC.
The output occurs by means of: See "Corresponds to ..." below
Corresponding to ... DB31, ... DBB86 - DBB87 (M function for spindle), axis-specific
DB21, ... DBB58, DBB68 - DBB97 (M function for spindle), channel-specific
