Upstream: The beginning of a motor or path as defined by the logical forward direction.
The upstream ends of all paths are connected to node controllers. Vehicles typ-
ically exit the motor or path on the
Downstream end.
V-Brace: The mechanical fixture that is used to align and secure MagneMover LITE
guide rail and motor sections.
Vehicle: The independently controlled moving element in a MagneMotion transport
system. The vehicle consists of a platform that carries the payload and a pas-
sive magnet array to provide the necessary propulsion and position sensing. All
vehicles on paths in the transport system that are connected through nodes
must be the same length.
The transport system constantly monitors and controls vehicle position and
velocity for the entire time the vehicle is on the transport system. All vehicles
are assigned a unique ID at startup and retain that ID until the transport system
is restarted or the vehicle is removed or deleted.
Vehicle Directives: The Demo Script commands that define the individual motion characteristics
for a specific vehicle. See also Global Directives .
Vehicle Gap: The distance between the bottom of the magnet array that is attached to a vehi-
cle and the top surface of a motor.
Vehicle ID Master Database: The HLC database for the assignment and tracking of Vehicle IDs in
the transport system. When using HLC Control Groups , the Master HLC main-
tains this database.
Vehicle ID Slave Database: The Slave HLC database for tracking of Vehicle IDs in the HLC Con-
trol Group managed by that Slave HLC and assigned by the Master HLC. This
database is only used when using
HLC Control Groups to subdivide a transport
system.
Vehicle Master: The motor controlling the vehicle.
Vehicle Signal: A motor software flag for each vehicle that is used to indicate if the vehicle is
detected on the transport system.
Vehicle Spacing: The distance between two vehicles on the same path.
Wheeled Puck: A preconfigured vehicle for use on MagneMover LITE transport systems that
uses low friction wheels to ride on the integral rails.
Zero Point: The position on the Upstream end of a Path that denotes the first part on which
a Vehicle travels.
