3.2.2 Configurating Example 2
The following settings should be made:
• 4 drive inverters
• Process data length 3
• Baud rate 500 kbit/s
01023AEN
Fig. 11: Example for configuration 2
Fig. 11 shows the system to be configured. The DIP switch settings are shown enlarged.
First of all, set the process data length and the baud rate on all the drive inverters. This is done on
the upper DIP switch block. See Table 1 for the setting of 3 process data words and a baud rate of
500 Kbit/s.
Then the basic ID is set for the drive inverters. In this example, the drive inverters are assigned the
basic ID in accordance with Table 6:
Table 6: Assignment of basic IDs for the drive inverters
As you can see, you need not observe a specific order when setting the basic ID via the DIP
switches. However, the basic IDs may not be assigned more than once, i.e. no two drive inverters
should have the same basic ID.
In addition, the terminating resistor must be connected at the line ends. Set the DIP switch identi-
fied by an 'R' on drive inverters 1 and 4 at ON.
