DBX82.0 - 82.2 Setpoint gear stage A to C
Edge evaluation: Yes
Edge change 0 → 1 The set gear stage is output in coded format:
Signal irrelevant ... Other spindle modes except oscillation mode
for ...
Corresponding to ... DB31, ... DBX82.3 (change over gear stage)
DB31, ... DBX16.0 - DBX16.2 (actual gear stage A to C)
DB31, ... DBX16.3 (gear is changed)
DB31, ...
DBX82.3 Change gear
Edge evaluation: Yes
Specification of gear stage:
● Manual specification using M function M41 - M45 corresponding to gear stage 1 - 5
● Automatic gear stage selection depending on the progr. Spindle speed via M-function M40
Edge change 0 → 1 New set gear stage was specified AND
set gear stage <> actual gear stage
Special cases, Signal is not output if: Set gear stage == actual gear stage
errors, ......

If set gear stage <> actual gear stage =>
DB31, ... DBX82.3 (change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (set gear stage) = set gear stage
at specified setpoint speed requires gear stage change =>
DB31, ... DBX82.3 (change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (setpoint gear stage) = setpoint gear stage
