Description
The application methods for PDO3 Rx and PDO4 Rx are the same as that for PDO2 Rx. For the relationship
between the settings and PZD in PROFIBUS communication, see
3.5.6
PDO3 Tx and PDO4 Tx
PDO3 Tx and PDO4 Tx are used by the VFD to transmit real-time process data to the master station, such as
running frequency.
The default transmission type of PDO3 Tx and PDO4 Tx is 254, and therefore PDO3 Tx or PDO4 Tx is
transmitted once data corresponding to a returned value in the same command changes.
