SGA SBH/SG active
This signal is used to signal the drive monitoring channel the status of the SBH and
SG functions as follows:
0 signal:
1 signal:
SGA status, pulses are cancelled (drive only)
After the shutdown path test has been initiated using the SGE test stop selection
or if a limit value is violated with a resulting STOP A response, this signal is output
to indicate that the drive pulses have been internally cancelled (refer to Subsec-
tion 6.1.1, "Shutdown paths").
0 signal:
1 signal:
SGA axis safely referenced
This indicates as to whether the relevant axis/spindle has been safely referenced
(see Subsection 5.4.3, "Axis states").
0 signal:
1 signal:
SGA SN1+, SN1–, SN2+, SN2–, SN3+, SN3–, SN4+, SN4–
These signals are used to indicate which of the plus or minus cams of cam pair 1,
2, 3 or 4 is "actuated".
0 signal:
Axis/spindle is located to the left of the cam (actual value < cam position)
1 signal:
Axis/spindle is located to the right of the cam (actual value > cam position)
SGA SBH active
The signal indicates the status of the safe operating stop (SBH).
1 signal:
0 signal:
SGA STOP A/B is active
This signal indicates that STOP A/B is active.
The signal must be used for the forced checking procedure for external STOPs.
0 signal:
1 signal:
