The control interface set under C4010 ( ^ 130) is used to cyclically transmit process data
to the axis module.
)
Note!
ƒ For communication between master control (path control) and drive system,
only the process data channels CAN1_IN and CAN1_OUT of MotionBus
interface X4 are used.
The MotionBus (CAN) serves ...
– to synchronise the control cycle of the slaves to the one of the control
master,
– to transmit the master value,
– to control the drive and
– if required, to transmit the monitor data for diagnostic purposes.
ƒ The system bus interface X14 can only be used for parameter setting and
diagnostics with the Lenze parameter setting and operating program
"Global Drive Control" (GDC).
ƒ Further information on communication can be found in chapter
"8 Configuration" (
^ 196).
