(T) Multi-Function Input Terminal Parameters
422
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
Change the torque at maximum analog input. (C18 (Pr.920), C40 (Pr.933))
• To only change the torque setting (gain) of the maximum analog input voltage (current), set to C18 (Pr.920), C40 (Pr.933).
