Note!
System bus (CAN)
The ECSxA...axis module can communicate with a higher−level host system
(PLC) or further controllers via both CAN interfaces (X4 or X14).
MotionBus (CAN)
The "MotionBus (CAN)" term expresses the functionality of the CAN interface
X4 in case of ECSxS/P/M... axis modules, where communication takes place
using a higher−level host system (PLC) or further controllers exclusively via the
X4 interface. Interface X14 (CAN−AUX) is exclusively used for parameter setting
and diagnostics.
Basic wiring of the CAN bus networks
The two following schematic diagrams show drive systems with different master value
concepts:
ƒ In Fig. 5−14 a higher−level control assumes the function of the master, e.g. ETC.
ƒ In Fig. 5−15 the function of the master is enabled by a controller intended as master.
In both representations, the master value transmission is effected via the
MotionBus (CAN), interface X4.
The system bus (CAN), interface X14, serves to diagnose and/or parameterise the drives.
