Startup Considerations
For robust startup operations, it is important that the configured vehicle length, not the
physical vehicle length, be shorter than the path where it is located during startup. For
example, a vehicle that is 300 mm long must not be started on a path that only consists of one
¼ meter or curve motor.
Collision prevention is only supported for vehicles that are started up in locations where the
system would move them during normal operation. There are conditions under which
manually located vehicles can collide after startup:
• Two vehicles on different paths of a switch, which are both within the gate protection
area (see Figure 9).
• Two wide vehicles next to a curve (see Figure 8).
Motion Considerations
Vehicle motion can become erratic when using wide vehicles due to the inertia created by the
wide vehicle as it enters and exits curves or the curve section of switches. This erratic motion
can cause a vehicle with a large offset payload to get stuck in a standard switch or take the
wrong path through a standard switch
The larger the payload on a vehicle, especially vehicles with large amounts of mass at the
edges of the vehicles, the larger the inertia. This larger inertia causes more erratic motion
through both curve motors and the curve section of switches. This erratic behavior becomes
worse as the mass or velocity is increased.
MagneMotion recommends the use of a high-payload switch in applications where this type
of erratic motion is observed.
