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 ter-
minal is used for a voltage input with jumper J1 connected.
D
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.
D
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.
D
If a 0 to
±
10 VDC input is set, H3-01 must also be set to a 0 to
±
10 VDC input.
