AC30V series Variable Speed Drive
Automatically Assigning an IP Address using DHCP
Parameter Setting
0929 DHCP TRUE
0930 Auto IP FALSE
If the network on which the AC30 is connected has a DHCP (Dynamic Host Configuration Protocol) server then the IP address may be assigned
by this server. The DHCP must be enabled. The AC30 will then request an IP address, subnet mask and gateway address from the DHCP
server.
Note: The IP address is requested by the AC30 each time the drive is powered up or when the Ethernet cable is plugged in. There is no
guarantee that the DHCP server will provide the same IP address each time.
Automatically Assigning an IP Address using Auto-IP
Parameter Setting
0929 DHCP FALSE
0930 Auto IP TRUE
The AC30 may assign itself a link-local address automatically using Auto-IP. This would be used where an automatic address is required but
where no DHCP server is available, such as a small local network or when connecting an AC30 drive directly to a PC (point to point). The Auto-
IP must be enabled.
The AC30 will choose an IP address randomly from the link-local range
169.254.*.* . The AC30 checks that no other Ethernet device on the
network is using the address before allocating it. The AC30 will store this IP address (in parameter 0931 Last Auto IP Address ) and attempt to
use it next time Auto-IP is used. The gateway address is fixed to 0.0.0.0
Using Both DHCP and Auto-IP
Parameter Setting
0929 DHCP TRUE
0930 Auto IP TRUE
0932 DHCP To Auto IP
The timeout in seconds before DHCP
gives up and an IP address is obtained
using Auto-IP
If both the DHCP and Auto-IP are enabled then an IP address will be obtained automatically depending on the network. First an attempt will be
made to obtain an IP address from a DHCP server (if connected). If after a timeout period a DHCP server is not available then a link-local
address will be obtained using Auto-IP.
Note: If an Auto-IP address is used and subsequently a DHCP server becomes available, no further request will be made to the DHCP server
until either the Ethernet cable is disconnected and reconnected or the AC30 is power cycled.
