SuperTrak Behavior
Each section has two (2) power connections:
• Motor power (28VDC for high power sections, 15VDC for low power sections,)
• Digital power (24V)
Motor power turns OFF with the safety circuit, but digital power remains ON.The
digital power maintains feedback from the encoders, so that the SuperTrak
conveyance platform continues to monitor the pallet positions.
The SuperTrak conveyance platform digital power turns ON when the main power
disconnect switch is placed in the ON position (if the SuperTrak conveyance
platform power disconnect switch is in the ON position). This provides power
to the SuperTrak conveyance platform controller, encoders, and other digital
electronics in the motors. The SuperTrak Conveyance Platform digital power can be
ON prior to the main disconnect turning ON if the UPS has battery power
remaining.
SuperTrak Conveyance Platform Power ON Behavior
When the system is in a safe state and cell power is ON, the system safety circuit
turns the fail safe output ON to the SuperTrak conveyance platform control panel,
which turns the SuperTrak conveyance platform motor power supplies ON. This
must only occur when the guard doors are closed and the system is in a safe state
to start operation. To avoid rapid switching of the SuperTrak conveyance platform
power supplies, the system safety circuit must be configured with a minimum 2
second delay after the fail safe output turns OFF before it turns back ON.
When the PLC is ready to allow pallet motion, the PLC enables the SuperTrak
conveyance platform by turning ON defined bits on the PLC network. Pallet
movement does not occur until the PLC enables pallet motion. The PLC can enable
pallet motion at the system level or for individual sections. The PLC must verify
that all robots and tooling are clear before it enables pallet motion.
When the PLC enables pallet movement, the SuperTrak conveyance platform
initializes the pallets, returns them to their proper starting location, and then
moves pallets as required.
The system startup procedure varies, depending on whether the UPS has timed
out or not and digital power was lost:
The SuperTrak conveyance platform is typically integrated with a larger
automation system. This section describes the SuperTrak conveyance
platform power ON procedure and does not include any steps for the
larger system.
