Node Address
The node address is established by means of two rotating switches on the electronic Profibus DP board, allowing
the addressing from 1 to 99. Looking at the board with the inverter in normal position, the leftmost switch sets
the ten of the address, while the rightmost switch sets the units of the address:
Address = (leftmost rotary switch x 10) + (rightmost rotary switch x 1).
Ten setting Integer setting

NOTE!
The node address must not be changed with the network in operation.
Configuration File (GSD File)
Each element of a Profibus DP network is associated to a GSD file that has all information about the element
operation. This file is supplied together with the product and is used by the network configuration program.
Signaling
The electronic board has a bicolor LED indicating the status of the Fieldbus according to the
Table 9.2 on page
9-4 .
Table 9.2: Fieldbus status LED signaling
LED Color Frequency Status
Red 2 Hz Fault during the test of the ASIC and Flash ROM
Green 2 Hz Board has not been initialized
Green 1 Hz Board has been initialized and is operating
Red 1 Hz Fault during the RAM test
Red 4 Hz Fault during the DPRAM test
NOTE!
The red signalizations may indicate hardware problems on the electronic board. Its reset is performed
by cycling the power of the inverter. If the problem persists, replace the electronic board.
The board also has other four LEDs grouped at the right bottom corner, indicating the Fieldbus network status
do Fieldbus according to
Figure 9.6 on page 9-4 and Table 9.3 on page 9-5 below.
