NOTE
• Even if the X14 signal is ON, PID control is stopped and multi-speed or JOG operation is performed when the RH, RM, RL, or
REX signal (multi-speed operation) 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 assignment using Pr.178 to Pr.189 or Pr.190 to Pr.196 may 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.)
• During PID operation, the remote operation function is invalid.
• When control is switched to PID control during normal operation, the frequency during that operation is not carried over, and
the value resulting from PID calculation referenced to 0 Hz becomes the command frequency.
