Rockwell Automation Publication MMI-UM002F-EN-P - October 2022
Platooning: A group of vehicles that are moving together and following a lead vehicle. This
group of vehicles is allowed to maintain a distance between each other while in
motion that is less than the Brick-wall Headway.
Position: A specific location on a Path, which is measured from the beginning of that
path, which is used as a vehicle destination. Position zero on any path is
defined as the leading edge of the first LSM in the path.
A vehicle at a specific position has its midpoint over that location on the path.
Power Supply: The equipment that is used to convert facility AC power to the correct voltages
for the transport system.
Propulsion Power: The power that is used for vehicle motion. See also, Logic Power.
Protected Area: The area around a node that is defined by the Entry Gates and Node Clearance
Distances. This area is used to make sure that vehicles do not collide with other
vehicles in the node or with the mechanism that is related to the node.
Puck: A preconfigured vehicle for use on MagneMover LITE transport systems. The
magnet array is mounted to the puck and interacts with the motors, which
move each vehicle independently. See Glide Puck and Wheeled Puck. See also,
Vehicle.
QS: See QuickStick.
QuickStick: A MagneMotion linear synchronous motor that enables quick, efficient con-
veyance of large loads on user-designed guideways and vehicles. QuickStick
(QS) motors move loads up to 100 kg [220 lb] per vehicle. QuickStick High
Thrust (QSHT) motors move loads up to 4,500 kg [9,900 lb] per vehicle.
QuickStick System: A group of specific components that contribute to a Transport System. These
components include QuickStick motors, Node Controllers, Motor Controllers
(QSHT only), Magnet Arrays, and other parts available from MagneMotion.
Sensor Map: A snapshot of the signal state of vehicle magnet array sensors that are collected
from all blocks of a motor.
Signal: Each motor contains sensors that detect the magnetic field from the magnet
array. When the signal from the sensors is higher than a threshold, the signal
bit for the associated sensor is set high, otherwise it is set low.
Single Vehicle Area: A unidirectional area of a Path. Only one vehicle that is moving in the speci-
fied direction of the area is allowed to enter the area at a time. Other vehicles
on the path that are moving in the same direction as the initial vehicle in the
SVA must wait to enter this area until the previous vehicle exits. This queueing
allows one vehicle to move backward and forward along a portion of a path
without interfering with any other vehicles.
Slave (also Slave Controller): The subordinate controllers for the motor, they communicate with
the Master and operate the Inverters and position-sense hardware. They are
internal to the motor assembly on MagneMover LITE and QuickStick motors.
For QuickStick HT motors the slaves are in the Drive.
