3. Main Power Supply and Motor Traces: The power traces must be kept as far
away as possible from the feedback and control traces.
4. PE Terminal: The PE terminal is connected directly to the Ocarina's heatsink or to
the Castanet's two PE strips on its lower board. In the Ocarina, the heatsink
serves as an EMI common plane. The PE terminal should be connected to the
system's Protective Earth. Any other metallic parts (such as the chassis) of the
assembly should be connected to the Protective Earth as well.
5. Under normal operating conditions, the PE trace carries no current. The only time
these traces carry current is under abnormal conditions (such as when the device
has become a potential shock or fire hazard while conducting external EMI
interferences directly to ground). When connected properly the PE trace prevents
these hazards from affecting the drive.
Follow these instructions to ensure safe and proper implementation.
Failure to meet any of the above-mentioned requirements can result
in drive/controller/host failure.
