Detailed Description
2.15 Spindles (S1)
DB31, ...
DBX30.2 Spindle start, counter-clockwise rotation
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.2 (spindle start, counter-clockwise)
edge change (corresponds to M4 counter-clockwise spindle direction of rotation for the master spindle)
0 → 1
Application The contents of the setting date:
example(s) SD43200 $SA_SPIND_S
can be read and become effective with the positive edge of the start signal "spindle start, counter-
clockwise direction of rotation".
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, ...
DBX30.3 Select gear step
Edge evaluation: yes
Signal state 1 or This function is presently being prepared. This is the reason that interface signal is temporarily
edge change reserved.
0 → 1
Application One parameter set each is provided for each of the 5 gear stages.
example(s) When changing over to the spindle mode, the corresponding parameter set 1 to 5 is selected
according to the gear stage engaged.
A gear stage can be preselected as follows:
•
•
•
•
Corresponding to .... MD35010 $MA_GEAR_STEP_CHANGE-ENABLE (the gear stage can be changed)
MD35590 $MA_PARAMSET_CHANGE-ENABLE (a parameter set can be specified by the PLC)
DB31, ... DBX82.3 (change over gear stage)
DB31, ...
DBX30.4 Spindle positioning
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.4 (spindle positioning)
edge change (corresponds to M19 position for spindle positioning)
0 → 1
Application If the spindle is to be stopped from direction of rotation (M3 or M4) with orientation, or is to be re-
example(s) oriented from standstill (M5), then the positioning mode is selected with SPOS, SPOSA or M19.
Corresponding to .... MD20850 $MC_SPOS_TO_VDI (for SPOS/SPOSA, "M19" is output to the VSI interface)
SD43240 $SA_M19_SPOS (position for spindle positioning with M19)
DB31, ... DBX84.5 (active spindle operating mode, positioning mode)

Signal(s) updated: cyclic
Signal(s) updated: cyclic
M40 automatically by the programmed spindle speed
M41 to M45 permanently by the part program
By the PLC, using function block FC 18
In the RESET state by writing to the VDI interface
Signal(s) updated: cyclic
Basic logic functions: NC/PLC interface signals (Z1)
