Tab. 5-165: Terminal 4 functional calibration parameter
Adjustment of the bias and gain for stall prevention operation level is done by Pr. 148 "Stall
prevention level at 0 V input" and Pr. 149 "Stall prevention level at 10 V input".
Torque change at maximum analog input (C18 (Pr. 920), C40 (Pr. 933))
To only change the torque setting (gain) of the maximum analog input voltage (current), set to C18
(Pr. 920), C40 (Pr. 933).
