12-10 Ethernet
AC30V series Variable Speed Drive
AN IP ADDRESS IS SET BUT THERE IS NO COMMUNICATION
If there is an IP address set but there are problems communicating with other devices (say a PC) then the IP address may not match the subnet
on which it is connected. The range of the IP address permitted on a network depends upon the particular network. Normally if the IP address is
obtained automatically then the settings will be correct for the network.
The administrator of a network should be aware of what IP settings are required.
LINK DETECTION
When the AC30 Ethernet is connected to a network or other device, the Ethernet Link LED will be on and the Ethernet Activity LED will be
flickering.
When first connected, the AC30 will attempt to determine the speed and duplex of the Ethernet link. This is done using a method call auto-
negotiation.
Some older devices or hubs do not support auto-negotiation, in which case the AC30 will use parallel detection. As parallel detection will only
provide the link speed, the AC30 will default to half-duplex.
