CANopen and CANlink Communication
‑43‑
Transmission Distance
The transmission distance of CANopen/CANlink bus is directly dependent on the baud
rate and communication cable. The mapping between the maximum transmission
distance of the bus and the baud rate is described in the following table.

3.3 Parameters
Table 3–10 Parameters
Para. No. Name Default
Value Range Description
Fd‑09
CANopen/CANlink
communication state
0
Ones (CANopen)
0: Stop
1: Initializing
2: Pre‑running
8: Running
Tens (CANlink)
0: Stop
1: Initializing
2: Pre‑running
8: Running
This read‑only parameter is used to
monitor the communication status.
Fd‑10
Communication
protocol selection
1
1: CANopen
2: CANlink
3: Communication card
mode
This parameter defines the CAN
communication protocol.
If it is set to 1, CANopen communication
is selected.
If it is set to 2, CANlink communication is
selected.
If it is set to 3, communication card
mode is selected.
You just need to set Fd‑10 of the power
supply unit. When the drive unit is
running, Fd‑10 of the power supply unit
cannot be modified.
