[. . . ] Hitachi Inverter SJ300/L300P SERIES SJ-PB(T) INSTRUCTION MANUAL Thank you for purchase of "HITACHI INVERTER". This manual explains about treatment of "SJ-PB(T) (Profibus-DP Option)". By reading this manual and an instruction manual of inverter use practically for installation, maintenance, and inspection. After reading this manual, keep it handy for future reference.

Requests and responses is a handshake procedure and cannot be batched, meaning that if the master sends out a read/write request, it has to wait for the response, before it sends a new request. The PKW is further divided into three parts; PKE- Parameter ID (2 bytes), IND ­ Sub-index (2 bytes) and PWEParameter value (4 bytes). PKW PKE PZD PZD1 STW ZSW IND PWE PZD2 HSW HIW PCD3 PCD4 PCD5 PCD6 PCD7 PCD8 PCD9 PCD10 PKW: Parameter ID/value. IND: Sub-index (3rd byte, 4th byte is reserved). PWE: Parameter value (4 bytes).

Range 1- 418 for Hitachi specific parameters and 900-999 for Profidrive specific parameters. Please refer to chapter 3. 5 for which Profidrive specific parameters that are supported. 11 CHAPTER5 OPERATING Request/Response handling The AK portion of the PKE word defines the request/response that may be issued. Since parameter length of the SJ300/L300P inverter may vary, parameter values are always transferred so that the least significant byte is placed in octet 8. If the Request/Response contains array elements, the high byte (byte 3) of the IND word will carry the array sub index, low byte (byte 4) is reserved for future use.

The describing fault number will be found in the PWE part. (note) Not supported by the SJ-PB(T) option board. 12 CHAPTER5 OPERATING 5. 3 PZD-part In this chapter the process data part (PZD) of a PPO is discussed. The PZD part consists of a fixed part (PZD1-2, all PPO's) and a parameterable part (PZD 3-10, shaded grey above, PPO 2, 4 and 5). In the fixed part, control word and speed reference are transferred to the inverter while status word and actual output frequency are transferred from the inverter. In the parameterable part, PZD word 3-10, the user can configure what parameters that should be transferred to/from the inverter every bus-cycle (see chapter 5. 3. 3 and Appendix). 5. 3. 1 Control- / status word (STW/ZSW) This section describes how to operate the inverter with the control-/status word. With the control word the Profidrive state-machine (Figure 5-2) is controlled, the status word is reflecting the state of the inverter. Profidrive Control Word (STW): The control word is used to send control commands to the inverter (PLC->Inverter).
