The number of available process data objects for inverters of the 8400 series depends on the device
version:
Receive PDOs (RPDOs)
The process data objects transmitted from the system bus to the drive are processed via the
...
• Every port block provides 4 words (2 bytes/word). The data of every first word are provided in a
bit decoded manner (bit 0 ... 15).
• The first word of the
port block is defined as control word
wCtrl
. The
wCtrl
control
word does not have a permanent connection to the device control and can be used as required.
The predefined assignment of the
wCtrl
control word in the
= "30: CAN" control mode
depends on the technology application selected in
