Process data object
RPDO1 | Port block "LP_CanIn1"
RPDO2 | Port block "LP_CanIn2"
RPDO3 | Port block "LP_CanIn3"
TPDO1 | Port block "LP_CanOut1"
TPDO2 | Port block "LP_CanOut2"
TPDO3 | Port block "LP_CanOut3"
Receive PDOs (RPDOs)
The process data objects transmitted from the CAN bus to the drive are processed via the
LP_CanIn1 ...
 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
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
C00007
C00005:
– TA "Actuating drive speed":
Process data assignment for fieldbus communication
– TA "Switch-off positioning":
Process data assignment for fieldbus communication
Transmit PDOs (TPDOs)
The process data transmitted from the drive to the CAN bust are processed via the
LP_CanOut1
 Every port block receives 4 words (2 bytes/word). The data of every first word are
transmitted bit by bit (bit 0 ... 15).
 The first word of the
wState status word does not have a permanent connection to the device control and
