5.5 -Dual Axis Interface Card
This card contains the interfaces necessary to connect 2
motor drives to the MX2000 controller. A stepper drive
or servo drive can be interfaced to the controller. In ad-
dition 4 dedicated inputs and up to 2 analog inputs can
be interfaced to each axis.
Up to four Axis cards can be plugged into an MX2000-8
back plane. Each axis card must be assigned a different
id (1-4) and id 1 must always be assigned to one of the
boards. The factory setting is board Id 1. For proper op-
eration, a Dual Axis board must always be plugged into
the MX2000 controller. The ID switches are located
behind the Analog output connector on the Dual Axis
card.
The 4 dedicated inputs for each axis are optically iso-
lated and can be either sinking or sourcing inputs. This
selection is made on the Dual Axis Interface card by
plugging the select jumper into the desired position. See
the card layout diagram to locate the jumper. The factory
setting is Sink.

5.5.1 – Stepper Drive Connections
The stepper drive connections are made to the STEPPER
DRIVE connector. If an encoder is attached to the step-
per motor the Encoder connections are made to the EN-
CODER connector. An illustration of this is provided.
The signal descriptions and equivalent circuits of each
connector will be covered later on in this section.
5.5.2 – Servo Drive Connections
The servo drive connections are made to the ANALOG
DRIVE connector. The encoder connections from the
motor are made to the ENCODER connector. An illus-
tration of this is provided. The signal descriptions and
equivalent circuits of each connector will be covered
later on in this section.
