7 Baud rate setting/line lengths
The transmission speed of the CANopen
®
communication module CM-CAN can be set
via the parameter CAN Baud rate 385.
The transmission rate is a function of a variety of application-specific parameters. The
line length of the communication network limits the transmission speed due to the
signal propagation time of the CANopen
®
Transmission rate 10 kBaud
Transmission rate 20 kBaud
Transmission rate 50 kBaud
Transmission rate 100 kBaud
Transmission rate 125 kBaud
Transmission rate 250 kBaud
Transmission rate 500 kBaud
Transmission rate 1000 kBaud
Changing the baud rate causes a restart of the CANopen
®
system (NOT a reset of
the inverter).
8 Setting the node number
The CANopen
®
protocol supports a maximum of 127 nodes in a communication net-
work. Each frequency inverter is assigned a node ID
, which may only exist once in the
system, for its unambiguous identification. The node number is set with
parameter
CAN Node Number 387.
The factory setting CAN Node Number 387 = -1 means that the CANopen
®
inter-
face has been deactivated.
The value Can Node number 387 = 0 is not allowed and cannot be set.
Changing the node number causes a restart of the CANopen
®
system (NOT a reset
of the inverter).
