How To Connect Teaching Tool When Grounding Positive Terminal Of 24-V Power Supply - IAI RoboNet Operation Manual

2.2.9 How to Connect Teaching Tool When Grounding Positive Terminal of 24-V Power
Supply
If the positive terminal of the 24-V power supply is grounded (= the +24-V side is grounded), use a SIO converter as shown
below to connect a teaching pendant or PC to the GateWayR unit. At this time, do not connect the FG of the SIO converter.

Do not

the FG.
24-V power supply
With the ROBONET, basically the negative terminal of the 24-V power supply is grounded (= the 0-V side is grounded).
Since most teaching pendants and PCs have their communication ground line and FG (frame ground) shorted internally,
grounding the 24-V power supply at the positive terminal (= grounding the +24-V side) will cause the 24-V power supply to
short when a teaching pendant or PC is connected to the GateWayR unit, resulting in damage to the teaching pendant or PC.
Caution
Do not connect the FG of the SIO converter.

Do not connect the FG of the PC to ground.
If the FC may be connected to ground
through other COM port, disconnect the
communication cable from the applicable
