Terminal name
Used as the power supply for an external frequency
setting (speed setting) potentiometer.
Inputting 0 to 5 VDC (or 0 to 10 VDC) provides the
maximum output frequency at 5 V (or 10 V) and makes
input and output proportional. Use Pr.73 to switch
between input 0 to 5 VDC (initial setting) and 0 to 10
VDC. This terminal can be used for voltage input only.
Inputting 4 to 20 mADC (or 0 to 5 V, 0 to 10 V) provides
the maximum output frequency at 20 mA and 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
(initial setting), 0 to 5 VDC, and 0 to 10 VDC. Set the
voltage/current input switch to the "V" position to select
voltage input (0 to 5 V or 0 to 10 V).
