E-stops
When using a node controller with digital I/O, the node controller can be connected directly to
an E-stop circuit. An E-stop is a user-supplied button (typically locking) that an operator can
press if an emergency situation arises to halt all motion on the specified paths. When the node
controller detects that the E-stop button is activated, it commands all paths that are associated
with that E-stop to suspend vehicle (puck) movement. All motors on those paths suspend
vehicle target requests and permissions and all vehicles come to a controlled stop and are held
in position by the motors. Stopping time for each vehicle is dependent on the load on the vehi-
cle and the acceleration setting of the current motion command for the vehicle. See the Node
Controller Hardware User Manual, MMI-UM013, for additional details and equivalent cir-
cuits.
NOTE: Motion cannot resume until the button is released and the host controller issues a
Resume command to the paths associated with the E-stop.
Interlocks
When using a node controller with digital I/O, the node controller can be connected directly to
an interlock circuit. An interlock is a user-installed circuit that another piece of equipment in
the facility activates to halt all motion on the specified paths temporarily. When the node con-
troller detects that the interlock circuit is activated, it commands all paths that are associated
with that interlock to suspend vehicle motion. All motors on those paths suspend vehicle tar-
get requests and permissions and all vehicles come to a controlled stop and are held in posi-
tion by the motors. Stopping time for each vehicle is dependent on the load on the vehicle and
the acceleration setting of the current motion command for the vehicle. See the Node Control-
ler Hardware User Manual, MMI-UM013, for additional details and equivalent circuits.
SHOCK HAZARD
The E-stop only executes the actions that are described, it is
not the same as an EMO (Emergency Off), which removes
power to the transport system.
AUTOMATIC MOTION HAZARD
When the interlock is cleared, automatic movement of the
vehicles on the MagneMover LITE transport system
resumes, which could result in personal injury.
