FAQ
Solution
Failure to write
frequency
1. Check the address in the configuration table based on F0‑03.
When F0‑03 is set to 0, the address should correspond to the
value of F0‑08. When F0‑03 is set to 9, the address should be
1000H or 7310H.
2. Check whether the termination resistor is connected. If not,
connect the termination resistor and then power on the AC
drive again.
Failure to start the AC
drive
1. Ensure that F0‑02 is set to 2 (communication). 0 means
operating panel and 1 means terminal.
2. Check whether the termination resistor is connected. If not,
connect the termination resistor and then power on the AC
drive again.
Unstable connection
1. Ensure stable connection on PLC side.
2. Ensure stable connection on AC drive side and firm contact
between the LAN cable and the LAN port.
3. Check whether the signal cable is close to the power cable.
Keep the signal cable away from the power cable.
Incorrect reading
1. Ensure that the address configured is correct.
2. Ensure that data conversion is performed.
3. Ensure that the D element is not occupied.
3.5.2 Configuration for CANopen Communication Between AC Drive and
H5U
Software Acquisition and Hardware Wiring
1. Log in to Inovance website http://www.inovance.com/support/download.html to
download the H5U programming software and the latest EDS file.
2. Connect one registered jack of a standard LAN cable to the CN3/4 port of the power
supply unit of the AC drive and connect the other end to H5U.
