(A negative voltage is a command for rotation in the opposite direction.)

Note When
the terminal is being used as a voltage input
terminal (setting 0 or 1), jumper J1 must be
disconnected
on the control board. (See the following diagram.) The terminal’
s
input resistor will
be destroyed if the terminal is used for a voltage input with jumper J1 connected.
• When
frequency references are being input simultaneously from both the voltage terminal 13 and
the
current terminal 14, the final reference value will be the sum of the two references that are input.
• To
switch the frequency reference input between the voltage terminal 13
and the current terminal 14,
set
a value of 1F in any one of the multi-function inputs (H1-01 through H1-06). The voltage terminal 13
will
be used when this multi-function
input is OFF and the current terminal 14 will be used when this
multi-function input is ON.
• The following diagram shows the location of jumper J1 on a 200-V Class, 0.4-kW Unit.

H Frequency Reference: Terminal 16 Voltage Input (H3-04 and H3-05)
This
function is useful
when switching between two analog inputs. When using this multi-function input
(terminal
16) as the frequency reference terminal, first set the multi-function analog input’
s function to
“Auxiliary
Reference” by setting parameter H3-05 to
“0.” (Neither H3-04 nor H3-05 can be changed dur
-
ing operation.)
