4.11.5.3 Examples of virtual links
Example 1:
Control word
Parameter 950 = Source-No. 740
Parameter 955 = Source-No. 62
The control word of frequency inverter 1 is linked with the control word of frequency
inverter 2. In this way, both frequency inverters can be operated synchronously via
the remote control. The output of the reference value channel of frequency inverter 1
is laid onto the output of the ramp of frequency inverter 2. In this way, both frequency
inverters have a joint source of reference values and are given reference values in the
internal notation.
As an extension, a number of frequency inverters can also exist on the receiving side
(Rx), which are supplied simultaneously with data parallel.
The input links not used in the TxPDO1 of frequency inverter 1 are set to ZERO and is
thus not be served.
