*1 The main speed setting is indicated.
• When the Terminal 4 input selection (AU) signal is turned ON, terminal 4 is used to set the main speed. In this case,
terminals 1 and 2 are not used to set the main speed.
• Set Pr.267 and the voltage/current input selection switch according to the following table.

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.
• The frequency setting auxiliary input through terminal 1 is added to the main speed setting signal input through terminal 2 or 4.
• When the override setting is selected, terminal 1 or 4 is set to the main speed setting, and terminal 2 is set to the override
signal (0 to 5 V or 0 to 10 V, and 50% to 150%). (If the main speed signal is not input through terminal 1 or 4, the compensation
by terminal 2 is disabled.)
• 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. Also, the acceleration/
deceleration time, which is a slope up/down to the acceleration/deceleration reference frequency, is not affected by the change
in Pr.73 setting.
• When "4" is set in Pr.858 Terminal 4 function assignment (Pr.868 Terminal 1 function assignment), the stall prevention
operation level is input through terminal 1 (4). To input frequency through terminal 1 (4), set "0 (initial value)" in Pr.858 (Pr.868).
• Always calibrate the input after changing the voltage/current input signal with Pr.73 (Pr.267) and the voltage/current input
selection switch.
• When Pr.561 PTC thermistor protection level ≠ "9999", terminal 2 is not used for the analog frequency command.
 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.
