3.1.3 Parameter Messages
The parameter messages, too, are divided into synchronous and asynchronous messages.
Synchronous parameter messages are responded to within the time interval of 1 ... X milliseconds.
The Response message is sent in the 1st millisecond.
The response to asynchronous parameter messages is independent of the time interval.

Configuration Examples
3.2.1 Configuration Example 1
The following settings shall be made:
• 4 drive inverters
• Process data length 1
• Baud rate 125 Kbit/s
01021AEN
Fig. 9: Example for configuration 1
Fig. 9 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 for the setting of one process data word and a baud rate of 125
Kbit/s.
Then the basic ID is set for the drive inverters. In this example the drive inverters are assigned their
basic ID in accordance with Table 4:
Table 4: Assignment of basic IDs for the drive inverters
Drive Inverter
Basic ID
1
000000 bin. = 0 dec.
2
000001 bin. = 1 dec.
3
000010 bin. = 2 dec.
4
000011 bin. = 3 dec.
ID = 0
ID = 1
ID = 2
