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.)
