Node address
(1) Configuring node address switches (SW1 and SW2)
Before the inverter power is turned ON, the node address of the communications card should be
specified with SW1 and SW2 (rotary switches) on the card. The setting range is from 00 to 99 in
decimal. SW1 specifies a 10s digit of the node address and the SW2, a 1s digit.
Node address = (SW1 setting x 10) + (SW2 setting x 1)
Note: The node address switches should be accessed with the inverter being OFF. Setting these
switches with the inverter being ON requires restarting the inverter to enable the new settings.
Note: To specify a node address exceeding 99, use the function code o31 as described in (2) below.
(2) Configuring the o31 data
The node address can also be specified with the inverter's function code o31. The setting range is from
0 to 125.
With both SW1 and SW2 being OFF, restarting the inverter validates the setting made with the
function code 31. If those switches are set to any value other than 00, the setting made with those
switches remains valid.
Setting the o31 data to 126 or greater flashes the ERR LED on the communications card, telling an
occurrence of a data setting error.
Selecting the PPO type
This communications card supports PPO types 1 through 4. For details about the PPO, refer to the
instruction manual of the PROFIBUS-DP communications card.
The same PPO type should be specified at both the inverter keypad and the PROFIBUS master. If not,
the communications card cannot start data exchange with the PROFIBUS master and flashes the ERR
LED, telling an occurrence of a data setting error.
From the inverter keypad

The PPO type of the communications card can be specified with the inverter's function code o30 that is
accessible from the inverter keypad after the communications card is mounted on the inverter.
After the setting of the PPO type is modified, the inverter should be restarted to validate the new
setting.

From the PROFIBUS master

The PROFIBUS master sends the definition of the communications card in its configuration frame.
The definition is stored in the GSD file. For the configuration procedure, refer to the PROFIBUS
master's manual.
