D
When the terminal is being used as a voltage input terminal (setting 0 or 1), jumper J1 must be discon-
nected on the control board. (See Figure 6.1.) The terminal’s input resistor will be destroyed if the termi-
nal is used for a voltage input with jumper J1 connected.
D
When frequency references are being input simultaneously from both the voltage terminal 36 and the
current terminal 39, the final reference value will be the sum of the two references that are input.
D
To switch the frequency reference input between the voltage terminal 36 and the current terminal 39,
set a value of 1F in any one of the multi-function inputs (H1-01 through H1-06).
The voltage terminal 36 will be used when this multi-function input is OFF and the current terminal 39
will be used when this multi-function input is ON.
D
If a 0 to ±10 VDC input is set, H3-01 must also be set to a 0 to ±10 VDC input.

Function and Signal Level for Multi-function Analog Input (Terminal 42): H3-04,
H3-05
D
This function is useful when switching between two analog inputs. The input is from terminal 42.
D
When using the multi-function input (terminal 42) as the frequency reference terminal, first set the mul-
ti-function analog input function to “Auxiliary Reference” by setting constant H3-05 to 0.

The auxiliary reference is factory-preset to 0.

After setting H3-05 to 0, set any one of the multi-function inputs (H1-01 through H1-06) to a value of
3 (multi-step speed reference 1).
D
When a multi-function analog input has been set to “Auxiliary Reference,” it is treated as frequency
reference 2 during multi-step speed operation, so it can’t be used unless the multi-step speed reference
1 has been set.
