Description: This machine data defines whether or not the NC waits for acknowledgment messages from
the PLC when the "Travel to fixed stop" function is active.
Bit 0 = 0
Once the NC has transmitted the interface signal DB390x DBX2.4 (Activate travel to
fixed stop) to the PLC, it starts the programmed traversing.
Bit 0 = 1
After the NC has transmitted the interface signal DB390x DBX2.4 (Activate travel to
fixed
stop) to
the PLC, it waits for the PLC to acknowledge with the interface signal
DB380x DBX3.1 (Enable travel to fixed stop) and then starts the programmed traversing.
Bit 0 = 1 should be set for analog drives so that the motion is not started before the
PLC has limited the torque in the drive.
Bit 1 = 0
Once the NC has transmitted the interface signal DB390x DBX2.5 (Fixed stop reached) to
the PLC, the program advances to the next block.
Bit 1 = 1
After the NC has transmitted the interface signal DB390x DBX2.5 (Fixed stop reached)
to
the PLC,
it waits for the PLC to acknowledge with the interface signal DB380x DBX1.1
(Acknowledge fixed stop reached), outputs the programmed torque and then advances to
the next block.
Bit 1 should be set for analog drives so that the PLC can switch the drive to torque-
controlled operation if a programmable clamping torque has to be specified.
With digital drives (PROFIdrive), the "Travel to fixed stop" function can be executed
without any acknowledgments, thus allowing program run times to be reduced.
