Coding 0 synchro-
nous,
acyclic
At every receipt of a SYNC a TPDO tele-
gram is transmitted on CAN.
1…240 synchro-
nous,
cyclic
In this setting range it is adjusted by means
of the value, how many SYNC telegrams
must be received, before a TPDO telegram
is transmitted on CAN.
ForparameterTPDO1...3thevaluetrans-
mission type = 0/1 means, that in status
OPERATIONAL a TPDO telegram is imme-
diately transmitted on CAN after receiving
a SYNC-telegram.
Forallsynchronousvalues ofthe tx_type
applies, that the SYNC-telegram triggers
the transmission of the appropriate TPDO
respectively the transmission of the RPDO.
Withtheexactvalueitisdeterminedhow
many SYNC-telegrams are necessary for
it. With the values 0 and 1 every SYNC ac-
tivates the corresponding event. The val-
ues 2 to 240 itself specify the number of
required SYNC-telegrams.
