CANopen & CANlink Communication
‑70‑
Common Problems and Solutions
The must‑dos are listed as follows:
1. Check the wiring. Check whether the wrong pins are wired as CANH and CANL to
the PLC.
2. Check the value of FD‑10. 1 indicates CANopen and 2 indicates CANlink.
3. Check whether the CAN communication baud rate defined by FD‑00 is consistent
with that of the PLC.
4. Check whether the CAN station number defined by FD‑02 is unique to avoid
conflicts with other drives.

Problem Solution
Failure to write
frequency
1. Check F0‑03 to confirm that the D component and the address
in the configuration table are correct (when F0‑03 is 0, the I/O
mapping is 2000sub8; when F0‑03 is 9, the I/O mapping is
2073sub11).
2. Check whether the terminal resistor is ON. If not, switch on the
terminal resistor and then power on the AC drive again.
Failure to start the AC
drive
1. Check that F0‑02 is set to 2 (0: Operating panel; 1: Terminal; 2:
Communication).
2. Check whether the terminal resistor is ON. If not, switch on the
terminal resistor and then power on the AC drive again.
