Motor Connections
for detailed information on connector placement. For each Atlas, connect the motor using the
chart below and the correct axis-specific 6-terminal jack screw plug on the carrier card, either J2, J5, J8, or J11 for axis
1, 2, 3, or 4 respectively. Use copper wire gauge 14AWG or larger to ensure that all current output requirements can
be met.
If you are using a one axis Atlas DK for motor connections and all other connections described in subsequent sections,
refer to the description for axis numbers.
A.2.3
Power Connections
For each Atlas, connect the bus supply voltage (HV) and the associated return ground signal at the correct axis-specific
jack screw plug, either J1, J4, J7, or J10 for axis 1, 2, 3, or 4 respectively. Once again, utilize AWG 14 or larger to ensure
that full current demand can be met while operating the unit. The power signals are lHV and GND.
For most installations you will use a single, common power supply to power all Atlas units. However this is not
required. If desired, you can operate different Atlas units at different voltages by connecting to different DC supplies.
A.2.4
Enable Signal Connection
You must provide an ‘active’ enable signal to allow Atlas to operate. There are a few options to accomplish this
depending on how you plan to operate your system. A simple approach is to use a short piece of AWG 20 or larger
wire to connect the GND connection on the spring clamp Phoenix connector to the Enable input (labeled ~Enab),
either J3, J6, J9, or J12 for axis 1, 2, 3, or 4 respectively.
For safety reasons, you may prefer to wire the enable input into a separate switch or E-stop button. Regardless of how
it is accomplished, the enable signal must be driven active (low) for Atlas to operate.
A.2.5
Installing and Connecting to the Magellan DK
Card
To set up and install the Magellan DK card refer to the Magellan Developer’s Kit product that you are using. This
manual will help you select jumper settings and make connections to the motor’s encoders and other connections.
Connect the Atlas DK’s SPI bus cable to the appropriate Magellan DK card connector.
Once all connections have been made you should power up the PC (but not the Atlas units) and follow the manual's
direction for installing Pro-Motion software. You can run Pro-Motion, check for encoder feedback, etc…. but for axes
that utilize Atlas amplifiers, motor output will not yet be operational.
