DBX82.3 Change gear
Edge evaluation: yes Signal(s) updated: Cyclic
Specification of gear stage:
• 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 stage selection depending on the progr. Spindle speed via M-function M40
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
Signal state 1 or
edge change
0 → 1
New set gear stage was specified AND
set gear stage <> actual gear stage
Special cases,
errors, ......
Signal is not output if: Set gear stage == actual gear stage
Corresponding to ... DB31, ... DBX82.0 - DBX82.2 (Setpoint 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(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The actual speed exceeds the maximum spindle speed:
MD35100 $MA_SPIND_VELO_ LIMIT
by more than the spindle speed tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL
Corresponding to ... MD35150 $MA_SPIND_DES_VELO_TOL (spindle speed tolerance)
MD35100 $MA_SPIND_VELO_LIMIT (maximum spindle speed)
DB31, ...
DBX83.1 Setpoint speed limited (programmed speed too high)
Edge evaluation: yes Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The effective setpoint speed exceeds the actual max. limit value. The setpoint speed is limited to this
limit.
Limit values:
• MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT (maximum speed of gear stage)
• MD35100 $MA_SPIND_VELO_LIMIT (max. spindle speed)
• DB31, ... DBX3.6 (spindle speed limitation to MD35160 $MA_SPIND_EXTERN_VELO_LIMIT)
• G26 (upper spindle speed limitation)
• LIMS (speed limitation for the master spindle if G96/G961/G97 is active)
• VELOLIM: Programmed spindle speed limitation in the open-loop speed controlled mode
• Safety Integrated
MD36931 $MA_SAFE_VELO_LIMIT (limit value for safely-reduced speed)
Signal state 0 or
edge change
1 → 0
The effective setpoint speed of the spindle is outside the maximum limit value.
