PARAMETERS
To run with an analog input voltage
• Concerning the frequency setting signal, input 0 to 5 VDC (or 0 to 10 VDC) to
terminals 2 and 5. The 5 V (10 V) input is the maximum output frequency.
• The power supply 5 V (10 V) can be input by either using the internal power
supply or preparing an external power supply. The internal power source is 5
VDC output between terminals 10 and 5, and 10 VDC output between
terminals 10E and 5.
• To supply the 10 VDC input to terminal 2, set "0, 2, 4, 10, 12, or 14" in Pr.73.
(The initial value is 0 to 5 V.)
• Setting "1 (0 to 5 VDC)" or "2 (0 to 10 VDC)" in Pr.267 and turning the voltage/
current input switches OFF sets the terminal 4 to the voltage input
specification. Turning ON the AU signal activates terminal 4 input.
NOTE
• The wiring length of the terminal 10, 2, 5 should be 30 m at maximum.
