DB31, ...
DBX83.5
Spindle in the set range
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The actual speed of the spindle deviates from the set speed by less than the spindle speed
tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL.
Signal state 0 or
edge change
1 → 0
The actual speed of the spindle deviates from the set speed by more than the spindle speed
tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL.
Normal status during the acceleration/deceleration phase of the spindle.
Signal irrelevant for
...
... All spindle modes except for control mode (speed mode).
Application
example(s)
Feed enable in the channel first with the end of the acceleration phase of the spindle:
IF ( DB31, ... DBX83.5 (Spindle in the set range) == 1 )
THEN ( DB21, ... DBX6.0 (Feed disable) = 0 )
ELSE ( DB21, ... DBX6.0 (Feed disable) = 1 )
Instruction: Axes positioning will also be stopped.
Corresponds to .... MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START
MD35500 $MA_SPIND_DES_VELO_TOL (spindle speed tolerance)

DBX83.7
Actual direction of rotation clockwise
Edge evaluation: yes Signal(s) updated: cyclic
Interface signal is only valid if the spindle is rotating:
DB31, ... DBX61.4 (axis/spindle stationary) == 0
The actual direction of rotation is derived from the position measuring encoder.
Signal state 1 or
edge change
0 → 1
Actual direction of rotation: Right
Signal state 0 or
edge change
1 → 0
Actual direction of rotation: Left
Signal irrelevant for
...
• Spindle is stationary: DB31, ... DBX61.4 (axis/spindle stationary) == 1
• Spindles without position measuring encoder
Corresponds to .... DB31, ... DBX61.4 (axis/spindle stationary)
