- *1 The safety input signal is negative logic (Active Low).
- If a signal level High is input to the safety input, this function will return 1 and the function assigned to the safety input will not operate.
If a signal level Low is input to the safety input, this function will return 0 and the function assigned to the safety input will operate. This occurs if a device is not connected to the safety input. - *2 The safety output signal is negative logic (Active Low).
- If one of the functions assigned to the safety output is operating, the safety output will be enabled, the signal level at the safety output will be Low, and this function will return 0.
If none of the functions assigned to the safety output are operating, the safety output will be disabled, the signal level at the safety output will be High, and this function will return 1.
If no function is assigned to the safety output, the signal level at the safety output will be Low and this function will return 0. - *3 If the target enters the monitored position, this function will return 1 regardless of whether or not the SLP function is assigned to the safety input as well as the input signal is enabled.
The cause of an error can be checked using STF_ID, STF_DET_L, or STF_DET_H. How to check using SPEL+ will be described later. The information for STF_ID, STF_DET_L, and STF_DET_H is as follows.

*1 The correspondence between the monitored parts J2, J3, J5 for Safety Limited Speed in Safety Function Manager and the speed exceeded parts hand, wrist, elbow, and shoulder referred in this manual is as follows:
- SCARA robots
- J2: Elbow
- J3: Not applicable
- J5: Not applicable
- Hand: Hand
- 6-axis robots
- J2: Shoulder
- J3: Elbow
- J5: Wrist
- Hand: Hand
*2 The correspondence between the monitored position X1, X2, Y1, Y2, Z1, Z2 for Safety Limited Position in Safety Function Manager and the monitored position XL, XU, YL, YU, ZL, ZU referred in this manual is as follows:
- When "Wall" is selected for the monitored position
- X1 = XL, X2 = XU
- Y1 = YL, Y2 = YU
- Z1 = ZL, Z2 = ZU (6-axis robots only)
- When "Restricted Area" is selected for the monitored position
- X1 = XU, X2 = XL
- Y1 = YU, Y2 = YL
- Z1 = ZL, Z2 = ZU (6-axis robots only)
How to check the cause of an error using STF_ID, STF_DET_L and STF_DET_H
Enter and confirm the commands in the following order in the command window and so on.
> SF_GetStatus (12)
115 'Indicates the error of "Stop notification SLP_A position exceedance".
> SF_GetStatus (13)
1 'Indicates that "YL" direction monitored position has been exceeded. (Check for STF_ID: 115.)
> SF_GetStatus (14)
1 'Indicates the "J2Flag" exceeded. (Check for STF_ID: 115.)
To summarize the above, we can see that the error occurred because "the J2Flag cross the monitored position in the YL of SLP_A."
Error information is also recorded in the Epson RC+ system history. The cause of the error is recorded in "Additional information". See SPEL+ error messages in the SPEL+ Language Reference manual.
This command can be used with the Controllers with Safety Board.
SF_GetStatus Function Example
If (SF_GetStatus(3) And &H1) = &H1 Then
Print "SAFETY_IN1 is High"
Else
Print "SAFETY_IN1 is Low"
