Inthefollowingchapter,physicalconnectionofthehardwarewillbeexplained.
Fieldbusgrounding
For AC500, which has optoisolated COM interfaces, it is recommended not to connect the ground. For AC500
eCo, where the COM interfaces are not optoisolated, it is recommended to connect the ground at one place,
typicallyinthebusmaster.Forconnectionexamples,seechapter“Installationexamples”.

Driveswithembeddedfieldbus
ThefollowingABBdriveshaveModbusRTUembedded:
ACS310
ACS/ACH550
ACS850
Since the builtin end termination of the drive automatically also activates pullup/pulldown resistors, it is
recommendedtoskipthebuiltinoption.
Itis recommended to connect a separateendtermination resistor to the first node (i
.e.thePLC COM interface)
andthelastnode(i.e.thelastdriveonthebus).
Forconnectionexamples,seechapter“Installationexamples”.
