Hitachi SJ-PB(T) instruction manual PPO- description, Operating

CHAPTER5 OPERATING

This section describes how to control the inverter via control word/status word and how to access the inverters parameters.

5.1 PPO- description

The structure of the user data is designated as parameter process data objects (PPO) in the Profidrive profile. The profile defines five PPO types, where SJ-PB supports all these PPO types.

There are PPO’s with a parameter area (PKW) and a process data area (PZD). There is also PPO’s that consist exclusively of process data (PZD).

1.PPO1 consists of the PKW area and 2 words PZD.

2.PPO2 consists of the PKW area and 6 words PZD.

3.PPO3 consists only of 2 words PZD.

4.PPO4 consists only of 6 words PZD.

5.PPO5 consists of the PKW area and 10 words PZD.

The user can configure what shall be transferred in PZD3-10 (shaded grey below), for more instructions of how to do this configuration see chapter 5.3.3, 5.4.2, 5.4.3 and Appendix.
