9999
Tab. 5-119: Terminal 1 functional calibration parameter
Use Pr. 148 "Stall prevention level at 0 V input" and Pr.149 "Stall prevention level at 10 V input" to
adjust the bias and gain for stall prevention operation level under V/F control and Advanced
magnetic flux vector control.
● Calibration parameter according to the terminal 4 function

Tab. 5-120: Terminal 4 functional calibration parameter
Use Pr. 148 "Stall prevention level at 0 V input" and Pr.149 "Stall prevention level at 10 V input" to
adjust the bias and gain for stall prevention operation level under V/F control and Advanced
magnetic flux vector control.
Change the stall prevention operation level at maximum analog input
(C18 (Pr. 920), C40 (Pr. 933))
To only change the stall prevention operation level setting (gain) of the maximum analog input volt-
age (current), set to C18 (Pr. 920), C40 (Pr. 933).
