• The second PID function parameters and signals function in the same way as the following parameters and signals of the
first PID function. Refer to the first PID function when setting the second PID functions.

NOTE
• Even if the X14 signal is ON, PID control is stopped and multi-speed or JOG operation is performed when the multi-speed
operation (RH, RM, RL, or REX) signal or JOG signal (JOG operation) is input.
• PID control is invalid under the following settings.
Pr.79 Operation mode selection = "6" (Switchover mode)
• Note that input to the terminal 1 is added to the terminals 2 and 4 inputs. For example when Pr.128 = "20 or 21", the terminal
1 input is considered as a set point and added to the set point of the terminal 2.
• To use terminal 4 and 1 inputs in PID control, set "0" (initial value) to Pr.858 Terminal 4 function assignment and Pr.868
Terminal 1 function assignment. When a value other than "0", PID control is invalid.
• Changing the terminal functions with Pr.178 to Pr.189 and Pr.190 to Pr.196may affect other functions. Set parameters after
confirming the function of each terminal.
• When PID control is selected, the minimum frequency becomes the frequency of Pr.902 and the maximum frequency becomes
the frequency of Pr.903.
(The Pr.1 Maximum frequency and Pr.2 Minimum frequency settings also are valid.)
