Yaskawa VS-616G5 Modbus Plus Communication Card - Manual (Page 116)

B-2 Command Priority
Command Priority
The setting of parameter b1-02 determines the origin of operation commands. This was
discussed in detail in Chapter 4, Establishing Communications. Some commands may be
accessed by a source other than the one set up by parameter b1-02, as illustrated in the tables B-
1, B-2, and B-3 on the following pages.
How to use the Command Priority Tables:
First, determine the source of control you wish to use for your VS-616G5 drive. Then b1-02
should be set up for the desired control you have chosen. (See the table below for parameter
settings.) Select the appropriate Command Priority table on the following pages based upon what
type of operation your drive is set up for.

The left hand column of the Command Priority tables is the source of the command (serial
communication, external terminals, and the Digital Operator). The middle column lists the
functions or commands, and the right most column indicates whether the functions are
operational (O) or not available (n/a) from each source.
