Perform stall prevention operation level bias/gain adjustment by using the Pr.148 Stall prevention level at 0 V input and Pr.149 Stall
prevention level at 10 V input.
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).
(Pr.902 to Pr.905 settings do not need to be changed.)
