These two, 2-pin Molex Minifit Jr. connectors allow you to control
"power-off" style 24VDC inline brakes. They can also be used as general
purpose outputs (GPOs) to control any 24VDC device through your
application code.

ASICS
•
Only two Brake Control outputs can be used per port. This
means, if 4 SC Hubs are chained together and connected to a
single USB or serial port, only the two brake outputs on the
first SC Hub in the chain would be useable.
•
Brake Control 0 and Brake Control 1 are linked to Axis 0 and
Axis 1 respectively. This is a fixed, relationship.
•
The Brake Control circuit was designed for use with 24VDC
"power-off" type brakes that draw 500mA or less.
•
Brakes will not release (allow motion) unless communication
with a motor has been established.
•
Brakes automatically engage (disallow motion) if
communication with the Application PC is interrupted.
Safety/Compliance Note: Ensure this feature is used only with ISO
13849 approved safety controls. Failure to do so could result in serious
injury or property damage. See the section "Safety Control Sketch (Brake
and Global Stop)" later in this section.
