Detailed Description
2.15 Spindles (S1)
DB31, ...
DBX84.7 Active spindle mode: Control mode
Signal state 1 or The spindle is in control mode with the following functions:
edge change
•
0 → 1
•
Corresponds to .... DB31, ... DBX84.6 (spindle mode oscillation mode)
DB31, ... DBX84.5 (spindle mode positioning mode)
DB31, ...
DBX85.5 Spindle in position
Edge evaluation: yes
The interface signal is processed exclusively with the function spindle positioning. This includes:
•
•
•
•
If the spindle travels with the already set signal DB31after positioning , ... DBX85.5 (Spindle in
position) e.g. in the mode JOG, then this signal is cleaned. If the spindle returns to its original
position in JOG mode, then the signal DB31, ... DBX85.5 (Spindle in position) is reset.
The last position selection is maintained.
A requirement for the sending of NST DB31, ... DBX30.4 (spindle positioning ) is the reference
status of the spindle. During a fault free run, the reference signal is always active at the end of the
positioning movement.
Signal status 1 or A requirement for output of NST DB31,... DBX85.5 (Spindle in position) is the arrival of NST DB31,
edge change ... DBX60.7 (Exact stop fine). Additionally the last programmed spindle position must have arrived
0 → 1 at the desired value.
If the spindle is already at the programmed position after a positioning, then signal DB31,...
DBX85.5 (Spindle in Position) remains set.
Signal status 0 or With the removal of NST DB31, ... DBX60.7 (Exact stop fine) , the
edge change NST DB31, ... DBX85.5 (Spindle in position) will always be reset.
1 → 0
Application Spindle in position for the tool change
example(s)
If the tool change cycle is interrupted by the machine operator e.g. with NC stop, NC stop axis plus
spindle, BAG stop etc., then the correct position in which the spindle must travel in the tool changer
must be queried via the
NST DB31, ... DBX85.5 (Spindle in position).
corresponds to .... DB31, ... DBX60.7 (Exact stop fine)
