• When Pr.809 = "9999" (initial value), speed limit is determined by the setting value of Pr.808 for both forward and reverse
rotations.

 Forward/reverse rotation speed limit using analog input (Pr.1113 =
"9999", Pr.807 = "2")
• When performing speed limit by analog inputs to terminal 1, speed limit can be switched between forward and reverse
rotation by its voltage polarity.
• When Pr.868 Terminal 1 function assignment = "5", forward/reverse speed limit is enabled.
• If 0 to 10 V is input, forward rotation speed limit is applied. Reverse rotation speed limit at this time is the value of Pr.1
Maximum frequency.
• If -10 to 0 V is input, reverse rotation speed limit is applied. Forward rotation speed limit at this time is the value of Pr.1
Maximum frequency.
• Upper speed limit is the value of Pr.1 for both forward and reverse rotations.
