Signals from axis/spindle (DB31, ...)

DB31, ...
DBX83.3 Geometry monitoring
Edge evaluation: No
Signal state 1 or edge Error in grinding wheel geometry.
change 0 → 1
Note:
There is no further reaction to the response of this monitoring function.
Reactions deemed necessary must be programmed by the PLC user.
Signal state 0 or edge No error in grinding wheel geometry.
change 1 → 0
Application exam‐ Grinding-specific tool monitoring

DBX83.6 Speed monitoring
Edge evaluation: No
Signal state 1 or edge Error in grinding wheel speed.
change 0 → 1
Note:
No further reaction to this signal state is programmed.
Reactions deemed necessary must be programmed by the PLC user.
Signal state 0 or edge No error in grinding wheel speed.
change 1 → 0
Application exam‐ Grinding-specific tool monitoring

DB31, ...
DBX84.1 GWPS active
Edge evaluation: No
Signal state 1 or edge Constant grinding wheel peripheral speed (GWPS) is active.
change 0 → 1
If GWPS is active, then all S value inputs from the PLC are interpreted as the grinding wheel periph‐
eral speed.
Signal state 0 or edge Constant grinding wheel peripheral speed (GWPS) is not active.
change 1 → 0
Application exam‐ GWPS in all operating modes.
