11.3.6 About Output Signals
11.3.6.1 Correspondence with Hard Wire
The following functions can be controlled either by hard-wire or by the
safety logic circuit.
Table 11-12: Hard-Wire Signal Name
Signal Name Hard-Wire signal name Explanation
S-EXDSW None • This is the external enable switch signal and functions only
in teach mode.
• When both the S-EXDSW signal and the enable switch on
the programming pendant are ON, the servo power can be
turned ON.
• When the S-EXDSW signal is not used in the safety logic
circuit, the safety circuit board regards this as the short-
circuit status.
S-EXESP EXESP • This is the external Emergency Stop input signal.
• When the S-EXDSW signal is turned OFF, the signal
performs the same control as the EXESP signal is turned
OFF.
• The hard-wired EXESP signal is always monitored. When
either the EXESP signal or the S-EXESP signal is OFF, the
servo power supply is turned OFF.
• When the S-EXESP signal is not used in the safety logic
circuit, the safety circuit board regards this as the short-
circuit status.
S-FST None This is the full speed mode signal.
Refer to chapter 11.3.6.3.
#n S-ONEN[x] #n ONEN[x]
This signal controls the servo power supply for each control
group.
(n indicates the number of the ASF01 board and x is 1 to 4. 4
points are available for one ASF01 board.)
When the S-ONEN signal is input, the signal performs the
same control as ON ENABLE signal.
When the hard-wired signal (ON ENABLE) is input, the servo
power supply for the appropriate control group is turned OFF.
When the signal is turned ON, the servo ON is enabled.
S-SAFF SAFF
When the S-SAFF signal is turned OFF, the signal performs
the same control as the SAFF signal. The hard-wired SAFF
signal is always monitored. When either the SAFF signal or the
S-SAFF signal is OFF, the servo power supply is turned OFF.
S-SVON_EN None
For details, refer to “YRC1000 INSTRUCTIONS
(RE-CTO-A221) chapter 8.26.13 “Enable Switch Link
Function ”.
MSOUT None
This is the data to transfer the data created in the safety logic
circuit to the functional safety function (optional).
NOTE
The signals which has been controlled by a hardware are
also always monitored. Thus, the safety function, which
turns OFF the servo power supply when the error is
detected, is maintained.
