SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Setting-up with the protective door open
•
Safely-reduced speed (SG1) spindle axes
(example values)
2m/min 50 rpm
•
The axes and spindles must stop when the door is opened, or the speed of
axis/spindle must be < SG1 (this must be ensured by the PLC user
program).
•
The PLC program interlocks the NC modes MDA and AUTO.
Setting-up with the protective door closed
•
Safely-reduced speed (SG2) spindle axes
(example values)
10 m/min
2000 rpm
(drives are monitored for maximum speed).
•
When the door is closed, Safety Integrated automatically changes over to
the SG2 limit
•
All NC operating modes are permitted when the protective door is closed.
Production with the protective door open:
•
The NC operating modes MDA and AUTO are disabled by the PLC
program – automatic mode is not permitted when the protective door is
open.
The safety function safe operating stop (SBH) is activated with the key-
operated switch position "Production" when the protective door is open.
This means that the drive is monitored for zero speed.
•
The axes and the spindle must stop when the protective door is opened
(this must be controlled by the PLC user program)
Production with the protective door closed:
•
Safely-reduced speed (SG2) ) axes
spindle
(example values)
10 m/min
2000 rpm
•
When the door is closed, Safety Integrated automatically changes-over to
the SG2 limit
•
All operating modes are permitted when the protective door is closed.
Once the safety functions have been defined function charts are drawn up for
the individual functions to which the
