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
... All spindle modes except for control mode (speed mode).
for ...
Application
Feed enable in the channel only at the end of the acceleration phase of the spindle:
example(s)
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)
DB31, ...
DBX83.2
Setpoint speed increased (programmed speed too low)
Edge evaluation: yes
Signal state 1 or
The set speed of the spindle that is specified directly (programmed spindle speed) or indirectly
edge change
(constant cutting speed) would violate the current minimum limit value. The set speed is therefore
0 → 1
defined at the minimum limit value.
Limit values:
•
•
•
•
•
Signal state 0 or
The set speed of the spindle is outside the minimum limit value.
edge change
1 → 0
Application
The interface signal indicates if the programmed set speed is unattainable. The feed can be
example(s)
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)
