*2 Use Pr.148 Stall prevention level at 0 V input and Pr.149 Stall prevention level at 10 V input to adjust bias and gain for setting the stall
prevention operation level.
 Changing the torque for the maximum analog input (C18 (Pr.920), C40
(Pr.933))
• Use C18 (Pr.920) or C40 (Pr.933) to change the torque setting (gain) for the maximum analog input voltage (current).
 Analog input bias/gain calibration (C16 (Pr.919) to C19 (Pr.920), C38
(Pr.932) to C41 (Pr.933))
• The "bias" and "gain" functions serve to adjust the relationship between a setting input signal and the torque. A setting
input signal is such as a 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mADC signal externally input to set the torque command or
the torque limit.
• Set the bias torque of the terminal 1 input using C16 (Pr.919). (The initial value is the torque for 0 V.)
