Actual value: Actual value is a 16-bit word, which contains converter operation information. Monitoring
capabilities are defined by VFD parameter. The integer scaling of actual value is sent to master

Control word (CW): The first word of PZD is control word (CW) of VFD. The definitions of CWs on the
PWM rectifier regenerative part are different from those on the inverter part, and therefore two tables
are used to describe the CWs.
