Siemens SINUMERIK 840D sl Function Manual page 2006

Detailed Description
2.1 Various interface signals and functions (A2)
DB10
DBX108.6 611D-Ready
Edge evaluation: no
Signal state 1 or All existing drives signal the status drive ready (summary of axial interface signals "DRIVE ready").
edge change 0 → 1
Signal state 0 or As soon as the drive not ready status is signaled from a drive
edge change 1 → 0 (i.e. IS "DRIVE ready" = 0).
Signal irrelevant for SINUMERIK 840Di
...
Corresponding to .... DB31, ... DBX93.5 (DRIVE ready)
DB10
DBX108.7 NC Ready
Edge evaluation: no
Signal state 1 or The control system is ready.
edge change 0 → 1
This interface signal is an image of the relay contact "NC Ready".
This signal is set if:
•
•
•
Signal state 0 or The control is not ready. The relay contact "NC Ready" is open.
edge change 1 → 0
The following faults will cause NC Ready to be canceled:
•
•
•
If the signal "NC Ready" goes to 0 the following measures are introduced by the control if they are
still possible:
•
•
For further information see References!
The control is not ready again until after POWER ON.

Signal(s) updated: cyclic
Signal(s) updated: cyclic
Relay contact "NC Ready" is closed
All the voltages in the control have been established
The control is in the cyclic mode
Undervoltage and overvoltage monitoring function has responded
Individual components are not ready (NCK CPU Ready)
NC CPU watchdog
The controller enable signals are withdrawn (this stops the drives)
The following measures are introduced by the PLC basic program:
Status signals from NCK to PLC (user interface) are deleted (cleared)
–
Change signals for help functions are deleted
–
Cyclic processing of the PLC to NCK user interface is terminated
–
Basic logic functions: NC/PLC interface signals (Z1)
