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 only at the end of the acceleration phase of the spindle:
IF ( DB31, ... DBX83.5 (spindle in set range) == 1 )
THEN ( DB21, ... DBX6.0 (feed disable) = 0 )
ELSE ( DB21, ... DBX6.0 (feed disable) = 1)
Note: Positioning axes are also stopped.
Corresponds to .... MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START
MD35500 $MA_SPIND_DES_VELO_TOL (spindle speed tolerance)

DBX83.2
Setpoint speed increased (programmed speed too low)
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The set speed of the spindle that is specified directly (programmed spindle speed) or indirectly
(constant cutting speed) would violate the current minimum limit value. The set speed is therefore
defined at the minimum limit value.
Limit values:
• Minimum speed of the specified gear stage
• Minimum spindle speed
• Speed limiting by means of NC/PLC interface
• Programmed spindle speed limiting G25
• Programmed spindle-speed limiting for G96
Signal state 0 or
edge change
1 → 0
The set speed of the spindle is outside the minimum limit value.
Application
example(s)
The interface signal indicates if the programmed set speed is unattainable. The feed can be
enabled nonetheless by means of the PLC user program.
The PLC user can accept this state as permissible and enable the path feed, or he can disable the
path feed or the complete channel, IS:
DB31, ... DBX83.5 (spindle in set range)
is processed.
Corresponds to .... DB21, ... DBX6.0 (feed disable)
DB31, ... DBX4.3 (feed/spindle stop)
DB31, ... DBX83.5 (spindle in set range)
