FC 300 Interbus Operating Instructions 5. How to Control the FC 300 5.2.1. The Drivecom State Machine The state machine describes the device status and the possible control sequence of the frequency converter. A status represents a specific internal and external response. By means of device control commands and/ or internal events, the status can be changed and a control sequence thus executed. The current status can be read out via the frequency converter’s status word.
