S748-772 Instructions Manual | 11 Expansions
11.1.8 Expansion module -2CAN-
2CANConnector X6 of the S700 is assigned to the signals for the RS232 interface and the
CAN interface. It is therefore not the standard pin assignment for these interfaces, and a spe-
cial cable is required to be able to use both interfaces simultaneously. The -2CAN- expansion
module provides the interfaces on separate Sub-D connectors. The two CAN connectors are
wired in parallel. A termination resistor (120 ) for the CAN bus can be switched into circuit if
the S700 is at the end of the bus.
11.1.8.1 Installation
The modul mu st be placed onto the option slot after levering off the cover of the option slot 1
(➜ # 126):
Screw the distance pieces into the fixing lugs of the option slot.
Place the expansion module onto the option slot.
Screw the screws into the threads of the distance pieces.
Plug the Sub-D9 socket into connector X6 on the S700
11.1.8.2 Connection technology
Standard shielded cables can be used for the RS232 and CAN interfaces.
If the servo amplifier is the last device on the CAN bus, then the switch for the bus ter-
mination must be set to ON.
Otherwise, the switch must be set to OFF (condition as delivered).
