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
machine depending on selected function, please refer to VFD manual.

Control word (CW): The first word of PZD is control word (CW) of VFD. The definitions of CWs on the
