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.
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.)
