Inputting 0 to 5VDC (or 0 to 10V, 0 to 20mA) provides the
maximum output frequency at 5V (10V, 20mA) and makes
input and output proportional. Use Pr.73 to switch from among
input 0 to 5VDC (initial setting), 0 to 10VDC, and 0 to 20mA. Voltage input:

Inputting 0 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA (5V, 10V) makes input
and output proportional. This input signal is valid only when the
AU signal is on (terminal 2 input is invalid). Use Pr.267 to
switch between the input 0 to 20mA (initial value) and 0 to
5VDC, 0 to 10VDC.
