Ethernet Setup

CONFIGURATION

To enable communications over the Ethernet an IP address must be set. With the default setting, an attempt at automatically obtaining an IP
address will be made.

Note: The IP address will be obtained or modified when an Ethernet cable is connected or the inverter is powered-up.

For the AC30P or AC30D if one port is already connected to a network, the IP address of the inverter will not be modified when the other port is
connected to a network.

The state of the Ethernet can be monitored using the parameter

0919 Ethernet State

and from the Ethernet icon

on the GKP status bar.

The current IP settings of the inverter can be monitored using the following parameters:

0926 IP Address

0927 Subnet Mask

0928 Gateway Address

The MAC address of the Ethernet port is fixed at the factory and can be read using the parameter

0945 MAC Address

ADVANCED CONFIGURATION

The IP address on the inverter may be set using the following methods:

•

Manually to a fixed address

•

Automatically by a DHCP server connected on the network

•

Automatically by the inverter to a link-local address using Auto-IP (also known as Automatic Private IP Addressing)

The parameters

0929 DHCP

and

0930 Auto IP

are used to determine how the IP address is set. The default of these two parameters is TRUE.

The parameter

0936 Setting Lock

, when set to TRUE, prevents a configuration tool from modifying the IP settings.

0935 User Gateway Address

If the network does not have a gateway to another network then the gateway address may be set to 0.0.0.0

Automatically Assigning an IP Address using DHCP

Parameter

Setting

0929 DHCP

TRUE

0930 Auto IP

FALSE

If the network on which the inverter 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 inverter will then request an IP address, subnet mask and gateway address from the
DHCP server.

Note: There is no guarantee that the DHCP server will provide the same IP address each time. The IP address is requested by the inverter when
the Ethernet port is connected to a network or when the inverter is powered up.

Automatically Assigning an IP Address using Auto-IP

Parameter

Setting

0929 DHCP

FALSE

0930 Auto IP

TRUE

The inverter 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 inverter directly to a PC (point to point). The Auto-IP
must be enabled.

The inverter 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 Inverter 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

Ethernet

12-6

TYPICAL WIRING CONFIGURATIONS

On the AC30P or AC30D either Ethernet port may be used.

Point to Point Connection

When connecting a PC directly to an inverter either:

•

Both sides use local-link addresses 169.254.*.* (recommended) , or

•

Both sides are set with a fixed IP address (each must be different and on the same subnet)

When using local-link addresses the parameter

0930 Auto IP

must be set to TRUE (see the section

Automatically Assigning an IP Address using

Auto-IP

). Normally the PC is already configured to allow for an Automatic Private IP address. However if problems are encountered check the

PC’s network settings (see the section

Troubleshooting the Ethernet – Changing the Ethernet settings on the PC).

Note: It may take some PCs up to 2 minutes to obtain an Automatic private IP address when the Ethernet cable is plugged in.

12-7

Ethernet

Local Network with a DHCP Server

For the inverter, the parameter

0929 DHCP

must be set to TRUE (see

the section

Automatically Assigning an IP Address using DHCP

Local Network without a DHCP Server

Devices on the network either:

•

Use fixed addresses, in which case the parameters

0929 DHCP

and

0930 Auto IP

must be set to FALSE (see the section

Advanced Configuration -

Manually Setting the IP Address

), or

•

Use link-local addresses, in which case the parameter

0930 Auto

must be set to TRUE (see the section Advance Configuration -

Automatically Assigning an IP Address using Auto-IP

Ethernet Daisy Chaining

The Ethernet on the AC30P or AC30D may be daisy-chained. The
order of the ports is not important, but it is recommended to follow the
order of, for example, Port 2 on the left-hand side inverter to Port 1
on the right-hand side inverter. However, an Ethernet loop MUST be
avoided.

Ethernet

TROUBLESHOOTING THE ETHERNET

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

No IP address - flashing GKP icon

Normally, once the inverter 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 inverter is waiting for a valid IP address to be set automatically, or 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 inverter 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.

Ethernet

12-12

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.

If connecting to a PC, the PC settings should also be checked – see the section

Changing the Ethernet settings on the PC

The administrator of a network should be aware of what IP settings are required.

Link detection

When the inverter 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 inverter 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 inverter will use parallel detection. As parallel detection will only
provide the link speed, the inverter will default to half-duplex.

12-13

Ethernet

Changing the Ethernet settings on the PC

Normally the PC Ethernet adapter is set to obtain an IP address automatically either from a DHCP server or using an automatic private IP
address (Auto-IP). The adapter settings may be checked / modified as follows:

For

Windows XP

under Control Panel



Network Connections

For

Windows 7

under Control Panel



Network And Sharing Center



Change adapter settings

Right-click on the required network adapter and choose Properties, then double-click on

Internet Protocol (TCP/IP)

(Windows XP) or

Internet

Protocol Version 4 (TCP/IPv4)

(Windows 7).

TROUBLESHOOTING THE WEB SERVER

Troubleshooting of the Ethernet in general is described in the section Troubleshooting below.

If the inverter web page still cannot be accessed then this may be due to the browser’s

proxy server

settings, especially if the PC has been used

on a corporate network. To check the settings, access the

Internet Options

dialog from within the browser and click on the

Connections

tab,

then click on

LAN settings

. Make sure the

Proxy server

checkbox is cleared, alternatively click on

Advanced

and add the IP address of the

inverter to the

Exceptions

list.

Contact your network administrator before making any changes to your browser settings.

12-18

Precision Time Protocol (PTP)

The Precision Time Protocol (IEEE 1588v2 or IEEE 1588-2008) is implemented in the AC30P and AC30D inverters.

The PTP will synchronize the internal clocks over the Ethernet to better than 1 microsecond. No external master is required for the PTP network;
any of the inverters may become a PTP master.

The initial use of the PTP is for shaft locking applications using the Virtual Master or Real Master control.

Note: Currently up to 16 inverters are supported on a PTP network.

CONFIGURATION

The two Ethernet ports provide a means of daisy chaining the inverters. The port order is not important, but an Ethernet loop must be avoided.
An external Ethernet switch should not be used, unless it is an IEEE 1588v2 transparent switch, as this will reduce the synchronization accuracy
by an indeterminate amount. Ethernet cables should be kept to a minimum length possible.

To enable the PTP set the parameter

1661 PTP Enable

to TRUE on all inverters participating.

In a PTP network, one device will be a master clock and the others will be slave clocks. On the AC30P or AC30D any inverter can become a
master or a slave clock. The decision on which inverter becomes the master is automatic when using the default parameter configuration.
However, it is possible to influence which becomes a master or slave by changing the PTP parameters.

Whilst the inverter is synchronising the icon on the GKP status bar

will flash. Once an inverter has become synchronised to the master

clock or has become the master clock, the diagnostic parameter

1688 PTP Locked

will be set to TRUE and he GKP icon

will stop flashing.

ADVANCED CONFIGURATION

PTP Modes
One-Step and Two-Step modes:

In one-step mode the hardware timestamping directly modifies the network packets, in two-step mode the

timestamps are stored and sent in a second step.

End-to-End (E2E) and Peer-to-Peer (P2P) Delay modes:

In E2E mode the slaves determine the delay between them and the master over the

whole network from end to end. In P2P mode each device only determines the delay to their nearest neighbour and adds this to the packets.
Standard Ethernet switches may be used with the E2E mode but is not recommended as it can add an indeterminate delay between clocks.

Address and ports

The PTP protocol uses the multicast IP address 224.0.1.129 and UDP ports 319 (event) and 320 (general).
