Downstream Gap

Rockwell Automation Publication MMI-UM002F-EN-P - October 2022
Downstream Gap: The physical distance from the end of the stator in one motor to the beginning
of the stator in the next motor downstream on the same path. This distance
includes the Motor Gap.
Drive: The remote QSMC motor controller or the QSHT 5700 inverter for a QSHT
motor.
Emergency Off: A user-supplied device that disconnects AC power to the transport system.
Emergency Stop: A user-supplied circuit with a locking button that anyone can press to stop
motion in the transport system. It can be wired through the digital I/O on some
Node Controllers.
EMO: See Emergency Off.
Entry Gate: The position on a path associated with a node where the leading edge of a vehi-
cle is considered cleared from the node. See Node Clearance Distance.
Entry Path: A path whose downstream end is a member of a node. A vehicle that is moving
downstream enters a node on an entry path.
Equivalent-Route Path: A path in a set of Moving Path node member paths that offers a route to a
destination that is reachable via any other path in the set.
E-stop: See Emergency Stop.
Ethernet Chain: Ethernet chains allow devices to be connected in series with standard Ethernet
cable, without the need for additional network switches. A daisy chain device
has two embedded Ethernet ports that function as an Ethernet switch and an
interface to the local device. This embedded switch allows information to flow
to the device, or flow through the ports to other devices in the chain.
Exit Path: A path whose upstream end is a member of a node. A vehicle that is moving
downstream exits a node on an exit path.
Fixed Path: A path whose position is fixed in the track layout. See Moving Path.
Following Vehicle: A vehicle following another vehicle in a platoon. This vehicle can be following
either the lead vehicle or another following vehicle.
Forward Direction: The default direction of motion, from Upstream to Downstream, on a Magne-
Motion transport system.
Glide Puck: A preconfigured vehicle for use on MagneMover
®
LITE transport systems that
uses low friction skids to slide on the integral rails.
Global Directives: The Demo Script commands that define the general operating characteristics
for all vehicles specified. See also Vehicle Directives.
Ground: The reference point in an electrical circuit from which voltages are measured.
This point is typically a common return path for electric current. See also PE.
Guideway: A component of the Track System that consists of rails or other devices in con-
tact with the Vehicle, either through wheels or low friction runners on the vehi-
cle. The guideway maintains the proper relationship between the vehicles and
