PC SMART 3AS is an open-loop CNC controller designed primarily for stepper motors that operate with step/direction signals.
However, it can also be connected to servo drives that support pulse and direction (step/dir) input mode, simply by wiring the controller’s output pins to the corresponding servo drive terminals.
