Option Card
<1> If two PG option cards are connected, use both CN5-B and CN5-C. If only one PG option card is connected to the drive, use the CN5-C
connector.
<2> These option cards are not available for the application with Motor 2 Selection.
<3> These option cards are not available with models CIMR-A†4A0930 and 4A1200.
<4> When AI-A3 and DI-A3 are to be used as monitors, the card can be connected to any of CN5-A, CN5-B or CN5-C. The input status of
AI-A3 can then be viewed using U1-21, U1-22, and U1-23, and the input status of DI-A3 can then be viewed using U1-17.
