(T) Multi-Function Input Terminal Parameters
416
PARAMETERS
Relationship between the analog input terminal function and the
calibration parameter
• Calibration parameter according to the terminal 1 function
• Calibration parameter according to the terminal 4 function
To change the frequency for the maximum analog input (Pr.125, Pr.126)
• To change only the frequency setting (gain) for the maximum analog input voltage (current), set Pr.125 (Pr.126).
(C2 (Pr.902) to C7 (Pr.905) settings do not need to be changed.)
