Linking Source to Sink Parameters
In order for information from a Source parameter to be input to a Sink
parameter, a link must be made between the two desired parameters. For
example, to send the information from Parameter 400 (first Source
parameter associated with Port A) to Parameter 151 (pre-defined as Logic
Cmd 2, input), then Parameter 151 must be linked to Parameter 400.
Linking of Parameter 151 to 400 is shown in Figure 5.3.
Linking of parameters is accomplished using the drive Setup Mode on the
Programming Terminal. The drive will allow a total of 20 links to be
made. There are two fixed links that cannot be altered or reconfigured,
thereby allowing a maximum of 18 user configurable links. Linking of
Sources to Sinks is referred to as “Configuring” the drive. For a complete
description of how to use the Programming Terminal to configure the
drive, refer to the Programming Terminal Instruction Manual. It should be
