Detailed Description
2.15 Spindles (S1)
DB31, ...
DBX82.0 - 82.2 Setpoint gear stage A to C
Corresponds to .... DB31, ... DBX82.3 (Change gear)
DB31, ... DBX16.0 - DBX16.2 (Actual gear stage A to C)
DB31, ... DBX16.3 (gear is changed)
DB31, ...
DBX82.3 Change gear stage
Edge evaluation: yes
Specification of gear stage:
•
•
Signal state 1 or New set gear stage was specified AND
edge change set gear stage <> actual gear stage
0 → 1
Special cases, Signal is not output if: Set gear stage == actual gear stage
errors, ......
Corresponds to .... DB31, ... DBX82.0 - DBX82.2 (Set gear stage A to C)
DB31, ... DBX16.0 - 16.2 (Actual gear stage A to C)
DB31, ... DBX16.3 (gear is changed)
DB31, ...
DBX83.0 Speed limit exceeded
Edge evaluation: yes
Signal state 1 or The actual speed exceeds the maximum spindle speed:
edge change MD35100 $MA_SPIND_VELO_ LIMIT
0 → 1 by more than the spindle speed tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL
Corresponds to .... MD35150 $MA_SPIND_DES_VELO_TOL (spindle speed tolerance)
MD35100 $MA_SPIND_VELO_LIMIT (maximum spindle speed)
124
Signal(s) updated: cyclic
Manual specification using M function M41 - M45 corresponding to gear stage 1 - 5
If set gear stage <> actual gear stage =>
DB31, ... DBX82.3 (change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (set gear stage) = set gear stage
Automatic gear step selection depending on the progr. Spindle speed through M-Function M40
For the previously given set speed, gear step change requires =>
DB31, ... DBX82.3 (Change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (Set gear step) = Set gear step
Signal(s) updated: cyclic
Basic logic functions: NC/PLC interface signals (Z1)
