 Setting multiple PID functions
• When the second PID function is set, two sets of PID functions can be switched for use. The PID setting is selected as
shown in the following table.
Pr.128 setting
(First PID setting)
"0" or not applied to the
frequency
"0" or not applied to the
frequency
Applied to the frequency
Applied to the frequency
*1 While Pr.155 = "0", the second function is enabled immediately after the RT signal turns ON. While Pr.155 = "10", the second function is enabled
only during constant speed operation when the RT signal turns ON. (For the details, refer to
• The parameters and signals for the second PID function are 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.
