NOTE
• For details on the addition compensation and override function, refer to
• Use C14 (Pr.918) Terminal 1 gain frequency (speed) to change the maximum output frequency at the input of the
maximum output frequency command voltage. At this time, the command voltage 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.
• To input frequency through terminal 1, set "0" (initial value) in Pr.868.
• Always calibrate the input after changing the input specification using Pr.73.
Performing forward/reverse rotation with the analog input (polarity reversible operation)
• Setting "10 to 17" in Pr.73 enables the polarity reversible operation.
• Set a positive or negative input (0 to ±5 V or 0 to ±10 V) to terminal 1 to allow the operation of forward/reverse rotation
according to the polarity of the input value.
