• High-voltage & current: Input from the DC power supply.
• Low-voltage: Signals
• STO Safety inputs
This graphic shows the traces from the EZ board as
an example of the zones on the UMB that have
different rules for spacings, etc.

These rules are good practice in the PC board design but are
not requirements to any standard.
Seven high-current traces are used for the
+HV, HVCOM, motor U/V/W outputs, Frame
Ground, and Protective Earth (PE)
Traces used on EZ board are paired on top
and bottom layers, connected by vias.
This gives a 3 oz, 0.50 inch width
combination
