Chapter 8 – CAN Interface (HG G-73350)
8.2.1.2 PDO_2
PDO_2 is sent with identifier 0x280 + node address. It contains exactly four 16bit
words (left-aligned) in the order Us1, Ud1, Us2, Ud2. The synchronous identifier
which is up to be received is 0x80. It can be read in index [1005,00].
The values transmitted in PDO_2 are based on the values shown in the status line
of the monitor program but are converted according to the following schema:
8.2.2 Receiving Objects
The frequency of the wires can also be changed using a non-cyclical receiving PDO.
Additionally, the RPDO can be deactivated/activated by setting/deleting the highest
bit in the corresponding PDO-COB identifier [1400,01].
The RPDO is expected on identifier 0x200 + node address. It contains 4 bytes for the
frequencies F1 and F2 in Hz. The order of the bytes within the 16bit words can be
altered using the CAN menu
(see 7.3.3 on page 24) or the SDO with index
0x2003,02 (Node config).
If values are transmitted which are not situated within the value range, they will be
ignored. Frequency changes are carried out as soon as the time, mentioned as fre
-
quency switch in the Technical Data (chapter 11 on page 47), is reached.
