Jumpers on the control unit:
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). If DIGND floats, the common of
digital inputs DI1…DI5 should be connected to
XD24:2. The common can be either GND or
V
cc
as DI1…DI5 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.
Continue with drive start-up according to the
instructions in the appropriate
Quick Start-up
Guide.
