Synchronization
The Synchronization option for the MagneMover LITE transport system provides the ability
for the end user to more accurately control movement of individual vehicles (pucks) within a
specified zone. More elaborate movement profiles can be implemented, such as jerk control. It
also provides the ability to co-ordinate vehicle motion to that of an external moving element,
(e.g. robot, filler, etc). Only those motors that are in a location where vehicle movement must
be synchronized with an external mechanism should use the Sync option.
In normal asynchronous operation, the Node Controllers route the orders from the Host to the
motors and the motors control the profiles (position, velocity, and acceleration) for the vehi-
cles. All asynchronous control is handled through the Node Controller’s RS-422 interface to
the motors.
In synchronous operation the profile (position, velocity, and acceleration) generation for indi-
vidual vehicles is the responsibility of the Host Controller, which generates profiles for all
vehicles in the synchronization region. This requires that the Host Controller be in charge of
collision avoidance. Once the vehicle leaves the sync region, the MMI control system picks
up profile generation and collision avoidance functions. The vehicle IDs assigned to the vehi-
cles by the transport system are preserved across non-Sync and Sync regions.
For synchronization, a SYNC IT controller is required for every three motors that are being
synchronized as shown in
Figure 6-6 . Refer to the LSM Synchronization Option User’s Man-
ual for configuration and operation details to use the Sync option with the MagneMover LITE
transport system.

NOTE: The SYNC IT controller is powered through its connection to the motors and does
not require any external source of power.
