Operation
NOTE
For any PC that will need regular configuration to communicate with a PositionServo Drive and if the
default PC Ethernet port on your computer is already being used for another purpose (such as email,
web browsing, etc,) then it may be more convenient for the operator to add an additional Ethernet
port to the PC.
The most common and cost effective way to do this is by using a USB / Ethernet dongle or a PCMCIA
Ethernet card. The additional port can be configured for communication to the PositionServo drive
without effecting the operation of other PC functions.
6.2.1 PositionServo Ethernet Port Configuration
The IP address of the PositionServo drive is composed of four sub-octets that are separated by three dots
to conform to the Class C Subnet structure. Each sub-octet can be configured with number between 1 and
254. As shipped from the factory the default IP address of a drive is:
192.168.124.120.
There are two methods of changing the current IP address. An address can be assigned to the drive
automatically (dynamic IP address) when the drive is connected to a DHCP (Dynamic Host Configuration
Protocol) enabled server, or the drive can have an IP address assigned to it manually be the user (static IP
address). Both methods of configuring the drive’s IP address are detailed herein.
6.2.1.1 Obtaining the PositionServo’s Current Ethernet Settings
The current Ethernet setting and IP address of the PositionServo drive can be obtained from the drive display
and keypad. Press the recessed ‘mode’ button (
) on the display and use the “UP” and “DOWN” buttons
(p q) to access parameters IP_1, IP_2, IP_3 and IP_4. Each of these parameters contain one sub-octet of
the full IP address, for example in the case of the drive default (factory set) address parameters:
IP_1 = 192
IP_2 = 168
IP_3 = 124
IP_4 = 120
By accessing these four parameters the full IP address on the drive can be obtained.
If parameters IP_1, IP_2, IP_3 and IP_4 all contain ‘----‘ rather than a numerical values it means that the
drive has DHCP enabled and the DHCP server is yet to assign the drive its dynamic IP address. As soon
as an IP address is assigned by the server the address assigned will be display by the drive in the above
parameters. See section on obtaining IP addresses through DHCP.
6.2.1.2 Configuring the IP Address Manually (Static Address)
When connecting directly from PositionServo drive to the PC without a server or when connecting to a
private network (where all devices have static IP addresses) the IP address of the PositionServo drive will
need to be assigned manually.
To assign the address manually, the drive must have its DHCP mode disabled. This can be done using
the drive keypad and display. Press the recessed ‘mode’ button (
) on the display and use the “UP” and
“DOWN” buttons (p q) to access parameter ‘DHCP’. Check this parameter is set to a value of ‘0’. If the
DHCP parameter is set to ‘1’ then use the ‘mode’ (
) and down (q) arrows to set to ‘0’ and then cycle
power to the drive in order for this change to take effect. When DHCP is disabled and power cycled to the
drive, it will revert back to its previous static IP address.
