The CVF-S1 utilizes digital and analog inputs for external control:
The is a series of low-power, single-phase variable frequency drives (VFDs) designed for general industrial applications, such as controlling three-phase AC induction motors. While often associated with the brand CONVO (acquired by the Bosch Group in 2006), these units are widely used for precision motor speed control in equipment like CNC machines.
