8.23.4.6 Message of Output Signals
The signals input by the hard-wired and the safety logic circuit display the
following messages on the programming pendant.
(Note) The upper line: the message by the hard-wired signal
The lower line: the message by the safety logic circuit
S-FST FST ࣭This is the full speed signal and functions only in the teach mode.
࣭When this signal is ON in the teach mode, the manipulator operation
speed can be switched to 100% output. The machine safety board
does not check the status of the hard-wired FST signal if the S-FST
signal is used in the safety logic circuit.
࣭The control status signal #80047 is turned ON/OFF.
#n S-ONEN[x] ON ENABLE[x] ࣭
This signal controls the servo power supply in units of control groups.
(n shows the number of the YSF22 board and x shows the available
point number. Four points can be controlled with a YSF22 board.)
When The S-ONEN signal is turned ON, the signal performs the
similar control to the ON ENABLE signal. Therefore, the servo power
of the connected control group can be individually turned ON/OFF.
࣭When the S-ONEN signal is not used in the safety logic circuit, the
machine safety board regards this as the short-circuit status.
࣭The control status signal #80061 is turned ON/OFF.
S-SAFF SAFF ࣭This is the safeguarding signal and functions only in the play mode.
࣭When The ONS-SAFF signal is turned OFF, the signal performs the
similar control to the SAFF signal. The hard-wired SAFF signal is
monitored at all times only in the play mode. When either the SAFF
signal or the S-SAFF signal is OFF, the servo power supply is turned
OFF.
࣭When the S-EXESP signal is not used in the safety logic circuit, the
machine safety board regards this as the short-circuit status.
࣭The control status signal #80023 is turned ON/OFF.
S-SVON_EN (None) For details, refer to chapter 8.23.4.7 .
MS-OUT (None) This is the data area to transfer the data created in the safety logic
circuit to the machine safety board.
