8.6.2 NORD system bus participants
Up to 8 frequency inverters with the associated absolute encoders can be integrated into the NORD
system bus. All participants on the NORD system bus must be assigned a unique address (CAN ID).
The addresses of the frequency inverters are “set with parameter
P515
“CAN Address
.
The addresses of connected absolute encoders are set via DIP switches. Absolute encoders must be
assigned directly to a frequency inverter. This is carried out using the following equation:
Absolute encoder address = CAN ID of the frequency in 1
This results in the following matrix:
Device FI 1 (SP 550P) AG 1 FI 2 AG 2 …
CAN-ID 32 33 34 35 …
The termination resistor must be activated on the first and last participant in the system bus (

Frequency inverter manual) The bus speed of the frequency inverter must be set to "250 kBaud"

“CAN Baud Rate
). This also applies to any absolute encoders which are connected.
