Commissioning
To disable DHCP, click the box again. Power must be cycled for any changes to [Configure IP Address] to take
effect. On changing any ethernet parameter value, the dialog box in Figure 17 will appear. Click [Ok] and cycle
power for changes to take effect.
4.3.4.3 Configuring the IP Address Automatically (Dynamic Address)
When connecting a PositionServo drive onto a network domain with a DHCP enabled server (where all devices
have dynamic IP addresses assigned by the server) the IP address of the PositionServo drive can also be
assigned automatically by the server.
To have the address assigned automatically the drive must have its DHCP mode enabled. This can be done
by using the drive keypad and display. Press the ‘mode’ button on the display and use the “UP” and “DOWN”
buttons to access parameter ‘DHCP’. Check this parameter is set to a value of ‘1’. If the DHCP parameter is set
to ‘0’ then use the ‘mode’ and up arrow to set to ‘1’ and then cycle power to the drive in order for this change
to take effect.
When the PositionServo drive is waiting for an IP address to be assigned to it by the server it will display ‘----‘
in each of the four octet parameters (IP_1, IP_2, IP_3, and IP_4) on its display. Once the address is assigned by
the server it will appear in these parameters. If this parameters continue to display ‘----‘ then it is likely that a
connection between the drive and server has not been established, or the server is not DHCP enabled.
DHCP can be enabled through the MotionView software for convenience should the operator wish to configure the
drive using a manual (static) IP address and switch over to an automatic (dynamic) address once configuration
is complete.
4.3.5 Re-Initializing
To activate any changes made the drive has to be reinitialized. Hence the warning within MotionView
Figure 17: REBOOT Message
This can be done by cycling the power to the drive.
4.3.6 Non-Communication Based Parameter Settings
In addition to configuring the Modbus settings and depending upon the application there may be several
drive based parameters that will need to be set using MotionView or an Indexer program or via the Modbus
parameter access channel. Such as:
• PID34 – Drive Mode (VAR_DRIVEMODE)
• PID37 – Reference (VAR_REFERENCE)
• PID29 – Enable switch funtion (VAR_ENABLE_SWITCH_TYPE)
