Detailed Description
2.15 Spindles (S1)
DB31, ...
DBX83.5 Spindle in the set range
Edge evaluation: yes
Signal state 1 or The actual speed of the spindle deviates from the set speed by less than the spindle speed
edge change tolerance:
0 → 1 MD35150 $MA_SPIND_DES_VELO_TOL.
Signal state 0 or The actual speed of the spindle deviates from the set speed by more than the spindle speed
edge change tolerance:
1 → 0 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 Feed enable in the channel first with the end of the acceleration phase of the spindle:
example(s) 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)
DB31, ...
DBX83.7 Actual direction of rotation clockwise
Edge evaluation: yes
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 Actual direction of rotation: Right
edge change
0 → 1
Signal state 0 or Actual direction of rotation: Left
edge change
1 → 0
Signal irrelevant for •

Signal(s) updated: cyclic
Spindle is stationary: DB31, ... DBX61.4 (axis/spindle stationary) == 1
Spindles without position measuring encoder
