(A) Application parameters
Setting the upper and lower limits of the PID manipulated amount (Pr. 1134, Pr. 1135)
● Set the upper and lower limits of the PID manipulated amount.
● The upper limit of the manipulated amount is the frequency obtained by adding the value
resulting from frequency conversion of Pr. 1134 to the main speed.
The lower limit of the manipulated amount is the frequency obtained by subtracting the value
resulting from frequency conversion of Pr. 1135 from the main speed.
