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 receive side 
(Rx), these then being supplied with data parallel and simultaneously. 
The input link not used in the TxPDO1 of frequency inverter 1 is on ZERO and is thus
not served.
