CANopen & CANlink Communication
‑64‑
7. Read the DI state.
Convert the DI state address U007 to 7007 based on the conversion rule, and
convert the read value into a binary value. The LSB indicates DI1, the second bit
indicates DI2, and so on.
The following figure shows the configuration and the program.
8. Read the fault code.
Convert the fault code address U045 to 702D and convert the fault subcode address
U046 to 702E based on the conversion rule.
The following figure shows the configuration and the program.
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 AC drives.
