External Control (I/O / Fieldbus) 32 DESKTOP ROBOT JR3000
2.13
AC Power Control of an External Device during an Emergency Stop
If the AC power supply to an external device for the tool attached to the robot is cut during an
emergency stop (the emergency stop switch has been pressed, etc.), construct a relay (such as
the one below) for the external device AC power supply input and connect the coil of this relay to
the #sysOut7 (Emergency Stop Output) signal on the I/O-SYS terminal of the robot.
*1:
The relay coil and I/O-SYS terminal connections are shown for a robot with an NPN external
power supply type.
For all other power supply types, make the connections by referring to the following:
•
NPN internal power supply type:
“2.7 Input Signal (NPN)” – “2.9 Circuit Diagram (NPN)”
•
PNP external power supply or PNP internal power supply types:
“2.10 Input Signal (PNP)” – “2.12 Circuit Diagram (PNP)”
*2:
Make sure to use a relay that adheres to the following:
•
Coil voltage: DC 24 V
•
Coil current: less than 100 mA
Relay Example: Force guided relay (Manufacturer: IDEC, Product No.: RF1V-2A2B-D24)
Coil voltage: DC 24 V
Coil current: 7.5 mA
Allowable contact voltage: AC 125 V, DC 125 V
Allowable contact current: 6 A
