Wiring
The safety related terminals are described in Table.2 and Table.3
Terminal
Symbol
For input of safety stop channel1.
S1-SC is
S1
Open: In safety stop mode.
Short: Non safety stop mode.
For input of safety stop channel2.
S2-SC is
S2
Open: In safety stop mode.
Short: Non safety stop mode.
As output for safety stop condition.
SO terminal type is 'Open collector output'.
SO-SC is
SO
OFF(Open): Drive enabled, or drive shutoff (with
(SAFE)
ON(Close): Drive shutoff (no internal circuit fault)
Important: SO terminal should be used for monitoring safety stop
condition only. SO terminal cannot be used for safety function.
Common terminal for S1,S2,SOsignals.
SC
*SC is connected terminal SD internally.
As output for failure detection and alarm. RUN terminal type is 'Open
collector output'.
RUN-SE is
OFF(Open): Detect failure or Alarm.
ON(Close): No failure detected.
RUN
(SAFE2)
Attention: To use RUN terminal for monitor output of failure
Note: This terminal can be used for alarm or to prevent restart only,
SE Common terminal for safety RUN signal.
As output for failure detection. A,C terminal type is 'Relay output'.
A-C is
OFF(Open): Detect failure or Alarm.
ON(Close): No failure detected.
A,C
(SAFE2)
Attention: To use A,C terminal for monitor output of failure
Note: This terminal can be used for alarm or to prevent restart only,
