DB31, ...
DBX83.1
Set speed limited (programmed speed too high)
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 maximum limit value. The set speed is therefore
defined at the maximum limit value.
Limit values:
•
Maximum speed of specified gear stage
•
Maximum spindle speed
•
Speed limited by VDI
•
programmed spindle speed limit
G26
•
programmed spindle speed limit for
G96
Signal state 0 or
edge change
1 → 0
The set speed of the spindle is outside the maximum limit value.
Application
example(s)
The interface signal:
DB31, ... DBX83.1 (set speed limited)
can be used to determine if the programmed speed is unattainable.
The PLC user can accept this state as permissible and enable the path feed, or can disable the
path feed and/or the complete channel, IS:
DB31, ... DBX83.5 (spindle in set range)
is processed.
DB31, ...
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 limitation
G25
•
programmed spindle speed limitation 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)
