Status and Error LEDs
Sabertooth 2x60 has three indicator LEDs.
The green LED marked Status is used to
communicate various information about the
current state. In most cases Status acts as a
power indicator. In R/C mode, it glows dimly if
there is no RC link present and brightly if there
is an RC link.
The green LED marked Cells will blink the
amount of cells you have attached when running
in Lithium mode. Cells will also illuminate along with the Error LED if you have tripped the
under-voltage alarm.
The red Error LED illuminates if the Sabertooth has detected a problem. It will light if the driver
has shut down due to a depleted battery or due to overheating, overcurrent or overvoltage. The
Error LED will flash along with Cells if there is an issue with your battery. If both of those are
blinking simultaneously, your battery is depleted.
Mounting your Sabertooth 2x60
The Sabertooth is supplied with four mounting holes. These can be used to attach it to your
robot. The centers of the mounting holes form a 3.25” x 2.75” rectangle. The holes are .125
inches in diameter. The proper size screw is a 4-40 round head machine or wood screw. Four
5/8” long machine screws and nuts are included.
Sabertooth 2x60 has an onboard fan and heat sink, so it has
slightly different mounting requirements than other
Dimension Engineering motor drivers which are passively
cooled. You do not need to worry about whether your
mounting surface is thermally conductive or insulating -
standoffs are not required from a thermal perspective.
However, to ensure adequate airflow, please ensure than
the top and sides of the unit are not tightly enclosed. Air is
drawn in by the fan on top of the unit, blown through the
large heat sink, and exhausted out the sides of the heat sink.
These three sides should be no less than 3/4" from the faces
of any enclosure to allow for adequate airflow.
