19.11 Spindles (S1)
DB31, ...
DBX83.0
Speed limit exceeded
Edge evaluation: Yes
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
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 (maximum 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
Edge change 1 → 0
The effective setpoint speed of the spindle is outside the maximum limit value.
