NOTE
• To enable terminal 4, turn ON the AU signal.
• Set the parameters and the switch settings so that they agree. Incorrect setting may cause a fault, failure, or malfunction.
• Use Pr.125 (Pr.126) (frequency setting gain) to change the maximum output frequency at the input of the maximum output
frequency command voltage (current). At this time, the command voltage (current) need not be input. The acceleration/
deceleration time is shown as a slope up/down to the acceleration/deceleration reference frequency. The acceleration/
deceleration time is not affected by the change in Pr.73 setting.
• Always calibrate the input after changing the voltage/current input signal with Pr.73 (Pr.267) and the voltage/current input
selection switch.
 Running with analog input voltage
• For the frequency setting signal, input 0 to 5 VDC (or 0 to 10 VDC) between 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 supply is 5 VDC output between terminals 10 and 5.

• To supply the 10 VDC input to terminal 2, set "0 or 10" in
• Set "1 (0 to 5 VDC) or 2 (0 to 10 VDC)" in
through terminal 4. Turning ON the AU signal activates the terminal 4 input.
Use an external power supply.

NOTE
• The wiring length of terminal 10, 2, and 5 should be 30 m at maximum.
 Running with analog input current
• For constant pressure or temperature control with fans, pumps, or other devices, automatic operation is available by setting
the regulator output signal 4 to 20 mADC to between terminals 4 and 5.
• To use terminal 4, the AU signal needs to be turned ON.
