11.4 PDO Function
The PDO (Process Data Objects) messages are messages with up to eight bytes of
process data. The process data objects are mapped to the Rx/Tx-
PDO’s with the help
of communication objects (communication/mapping parameter). Active Cube inverters
support 3 RxPDO’s (PLC inverter) and 3 TxPDO’s (inverter PLC).
Process data objects are directly linked to application functions of the inverter.
PDO-message:
The number of data bytes is 1 … 8 and depends on the mapped objects. The byte
alignment is in Intel format.
TxPDO1 384 + Node-ID
RxPDO1 512 + Node-ID
TxPDO2 640 + Node-ID
RxPDO2 798 + Node-ID
TxPDO3 896 + Node-ID
0x180 + Node-ID
0x200 + Node-ID
0x280 + Node-ID
0x300 + Node-ID
0x380 + Node-ID
11.5 Emergency Function
In the event of a communication error or an error inside the inverter, the inverter
sends an emergency message. This emergency message includes the relevant error
information. After error acknowledgement (fault reset), an emergency message is
sent with all data bytes set to zero.
EEC: Emergency Error Code according to DS301
ER: Emergency Register Code according to DS301
MEC: Manufacturer Error Code
The Manufacturer Error Code corresponds to the inverter Fault codes that are de-
scribed in the Operating Instructions and in this documentation in chapter 16.5 “Fault
Additional information is described in chapter 12.2.13 “0x1014/0 COB-ID Emergency
Message”.
