3.5.4 PDO2 Tx
PDO2 Tx is a command transmitted by a VFD to the master station. It contains a SW and
real-time process data (Returned value 1, returned value 2, and returned value 3). A SW is
used to notify of the state of the VFD, and returned values are used to transmit the real-time
running values of VFD, such as running frequency.
The default transmission type of PDO2 Tx is 254, and therefore PDO2 Tx is transmitted once
data corresponding to a SW or returned value changes.

Description
A SW is two bytes. Byte0 is the LSB, and Byte1 is the MSB. Table 3-18 describes the
definitions of the Goodrive350 series VFD SWs. For VFD of other series, see the
corresponding VFD operation manual.
