VFDs and motors have two way of operation, in the US we use CW and CCW, in the rest of the world, or INT (International) it is used START/STOP and DIRECTION. These settings can usually be adjusted VFD settings.  The chances are that if you purchased the VFD in the US, it came pre-configured for US mode, and if you purchased it overseas, it came in INT mode.  Our Breakout boards take Step (PWM) and Direction Control, and pending on the position of the jumpers on the circuit, it activates the relays in the appropriate way.
