servo wiring

Translating a superb theoretical design into a reliable servo requires attention to the mundane practical details that often eludes a gifted designer’s interest.
Poorly designed ground connections, for example, can lead to inadequate protection against common mode errors—or crosstalk in multi-axis motion control systems.  Power supply selection that’s left to last moment decision may inhibit servomotor acceleration.  Or the unusual duty cycles of a PCB drilling system—if not anticipated—cause MTBF-degrading heat dissipation.  And don’t wait for a power supply explosion to focus attention on regenerative braking deficiencies.
This article may help differentiate between a superbly performing servo, and persistent problems that create customer friction or costly field fixes.
