Ethernet 12-9
AC30V series Variable Speed Drive
Troubleshooting
The following parameters are useful for monitoring the IP settings:
0929 IP Address
0928 Subnet Mask
0931 Gateway Address
The state of the Ethernet can be monitored using the parameter 944 Ethernet State, normal operation is when the state is RESOLVED IP, and
from the GKP icon
FLASHING GKP ICON
Normally, once the AC30 is connected to a network, the GKP Ethernet icon will flash for a short period as the IP address is being resolved, and
then will become a solid icon indicating an IP address has been set. If the icon continues to flash for more than 1 – 2 minutes this can indicate a
problem. Check the parameter 0919 Ethernet State.
RESOLVING IP
The AC30 is waiting for a valid IP address to be set manually using the parameters:
0933 User IP Address
0934 User Subnet Mask
0935 User Gateway Address
Note that the IP address must be set to a non-zero value.
RESOLVING DHCP
The AC30 is waiting for a DHCP server to provide an IP address. If there is no DHCP server detected on the network then the Ethernet will stay
in this state. If there is no DHCP server the IP address may be obtained using Auto-IP or set manually.
DUPLICATE IP
Another device on the network with the same IP address has been detected. This will cause communication issues. The Duplicate IP warning
will clear after approximately 1 minute once the conflicting device has been removed or the IP address changed.
