CAN Communication Plug-in Module
To connect the CFW500 frequency inverter using this
module, the following points must be observed:
It is recommended to use specific cables for
„
CANopen networks.
Grounding the cable mesh in only one site, thus
„
avoiding current loops. This point is often the source
of mains power. If more than one power supply
is used, only one of them must be connected to
ground protection.
Install termination resistors only at the ends of the
„
main bus, even if there are derivations.
The power supply network must be capable of
„
supplying current to operate all the equipment
transceivers. The CF W500 CANopen module
consumes approximately 50 mA.
For further details on the installation of network,
CANopen, DeviceNet and communication see in there
CD-ROM, the manual user's, respectively.
This module has a connector
use of the CFW500-MMF Flash Memory Module , which
allows data transfer between inverters. For further details
on this accessory, refer to the installation and operation
guide of the CFW500-MMF.
