When the DHCP or BOOTP function is used, the MAC address of the expansion card is
required. You can obtain the MAC address by checking the label on the expansion
card, or viewing the related parameter of the AC drive.
The MD500‑EN1 expansion card also supports the IP address conflict detection
function. When the IP address of this card is the same as that of another device in the
network, the red indicator D7 becomes steady on, and bit2 of FD‑58 changes to 1.
There are three IP address conflict situations, as described in the following table.
No. Scenario
Symptom
Solution
1
Both devices support
IP address conflict
detection.
The two devices are
powered on at
different time.
The device powered
on first keeps the IP
address and
continues to run,
and the other device
enters conflict mode.
Check device IP
addresses and
change duplicate
addresses.
2
Both devices support
IP address conflict
detection.
The two devices are
powered on at
almost the same
time.
Both devices enter IP
address conflict
mode.
3
One device supports
IP address conflict
detection while the
other does not.
The device that does
not support IP
address conflict
detection occupies
the IP address no
matter whether it is
powered on first.
The device that
supports IP address
conflict detection
enters conflict mode.
