Supplementary Conditions For Expansions - Siemens SINUMERIK 828D Function Manual

MD37052
With the machine data MD37052 $MA_FIXED_STOP_ALARM_REACTION, the drive is not disconnected from
the power supply by setting the bits, even when an alarm is generated, as the NC/PLC interface signal
DB11 DBX6.3 (mode group ready) remains active.
Bit value=0:
The alarms have an effect on FXS (drive becomes disconnected as previously).
NST DB11 DBX6.3 (mode group ready) is deleted.
Bit value=1:
The alarms have no effect on FXS.
NST DB11 DBX6.3 (mode group ready) remains active.
Bit Alarm Meaning
0 20090 Travel to fixed stop cannot be programmed
1 20091 Fixed stop is not reached.
2 20092 Travel to a fixed stop active.
3 20093 Standstill monitoring on fixed stop is triggered.
4 20094 Travel to fixed stop aborted.

Response to pulse blocking
The cancellation of the pulse enable, either using terminal EP (Enable Pulses) or using IS DB31, ... DBX21.7
("Pulse enable") is known as pulse blocking in the following.
The machine data:
MD37002 $MA_FIXED_STOP_CONTROL
can be used to influence the interaction of travel to fixed stop and pulse blocking.
Bit 0: Response in case of pulse blocking at stop as follows:
Bit 0 = 0
Bit 0 = 1
Once the pulse blocking is canceled again, the drive will press at the limited torque again. The torque is actuated
step­like.
Programming FXS in synchronized actions
The function is not available for analog axes (PLC acknowledgment cannot be awaited).
Select FXS[ ]=1:
The following signal interfaces are set:
