Tab. 5-159: Terminal 4 functional calibration parameter
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). (C2 (Pr. 902) to C7 (Pr. 905) settings do not need to be changed.)
