This signal indicates the status of safe operating stop (SBH) (refer to Chapter 3,
"Safe operating stop (SBH)").
1 signal: SBH is active
0 signal: SBH is not 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: STOP A/B is not active
1 signal: STOP A/B is active
This signal indicates that STOP C is active.
The signal must be used for the forced checking procedure for external STOPs.
0 signal: STOP C is not active
1 signal: STOP C is active
This signal indicates that STOP D is active.
The signal must be used for the forced checking procedure for external STOPs.
0 signal: STOP D is not active
1 signal: STOP D is active
This signal indicates that STOP E is active.
The signal must be used for the forced checking procedure for external STOPs.
0 signal: STOP E is not active
Otherwise: STOP E is active
This SGA indicates whether the absolute value of the actual speed is above or
below a speed specified in the machine data.
1 signal: Actual speed is lower than the limit speed
0 signal: Actual speed is greater or equal to the limit speed
