Jumpers

DI/DIO grounding selector (located between XD24 and XDI) – Determines whether
the DIGND (ground for digital inputs DI1...DI5) floats, or if it is connected to DIOGND
(ground for DI6, DIO1 and DIO2). See the JCU isolation and grounding diagram on
page 121.
If DIGND floats, the common of digital inputs DI1...DI5 should be connected to
XD24:2. The common can be either GND or V
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.
