DI/DIO grounding selector (located between XD24 and XDI) – Determines whether the
DIGND (ground for digital inputs DI1…DI4) floats, or if it is connected to DIOGND (ground
for DI5 DIO1 and DIO2). See the JCU isolation and grounding diagram on page 115.
If DIGND floats, the common of digital inputs DI1…DI4 should be connected to XD24:2.
The common can be either GND or V
cc
as DI1…DI4 are of the NPN/PNP type.
AI1 – Determines whether analog input AI1 is used as a current or voltage input.
AI2 – Determines whether analog input AI2 is used as a current or voltage input.
T – Drive-to-drive link termination. Must be set to the ON position when the drive is the last
unit on the link.
