The terminal used to clear frequency-increase/decrease
setting can clear the frequency value of auxiliary channel
set by UP/DOWN, thus restoring the reference frequency
to the frequency given by main reference frequency
command channel.
This function is used to switch between the frequency
setting channels.
A frequency reference channel and B frequency
reference channel can be switched by no. 13 function;
the combination channel set by P00.09 and the A
frequency reference channel can be switched by no. 14
function; the combination channel set by P00.09 and the
B frequency reference channel can be switched by no. 15
function.
16-step speeds can be set by combining digital states of
these four terminals.
Note: Multi-step speed 1 is low bit, multi-step speed 4
is high bit.
