Chapter 6 Parameter Description

8 Communication reference、
It means that the main frequency source is given by the host
computer via the communication mode .
When the auxiliary frequency source is used as independent
frequency reference channel , its usage is as the same way as
that of the main frequency source .
When the auxiliary frequency source is used as overlap
reference , it has special points as follows

1:When the auxiliary frequency source is digital reference ,
the preset frequency F0.08 has no action , and it can be
adjusted on the base of the main reference frequency by the keys
and ” (or UP and DW terminals ) .

When the frequency source selection is frequency overlap
reference F0.07 is set to 2 it is used to determine the
adjustment range of auxiliary frequency source . F0.05 is
used to determine the relative object of that range . If it is
relative to upper limit frequency F0.11 , this rangeis a fixed
value ; if it is relative to main frequency source X ,
this range will vary along with the variety of the main
frequency X .
（），
well then
When the frequency source selection is auxiliary frequency
source Y F0.07 is set to 1 and F0.05 is set to 1 , simple
and convenient control can be realized through
setting the main frequency source X as the main frequency
standard and the auxiliary frequency source as the synchronous
coefficient to make corresponding setup .

2:When the auxiliary frequency source is analog input
reference
（）AI1 and AI2 or pulse input reference , the 100%
of input setup is relative to the auxiliary frequency source range
( refer to F0.05 and F0.06 ) . If adjust on the base of the main
reference frequency , please set the corresponding setup
range of analog input into -n% to +n% (refer to F3.08 to F3.15).
3:When the frequency source is pulse input reference , it is
similar to the analog value .

This parameter is used to select the frequency
reference channel . Frequency reference is realized
by the combination of the main frequency source X and
the auxiliary frequency source Y .
When 2 is selected it can realize frequency overlapping
function .
，
When 3 or 4 or 5 is selected, the frequency source switching
is realized by the X input terminal frequency source
switching function .
“
”
In this way ,mutually switching between the frequency
reference modes can be realized, for example, switching
between PID running and common running , switching
between simple PLC and common running , switching
betweenpulse setup and analog setup , and switching
between analog setup and common running .
