Torque command (Pr. 804 = 0 (initial value)) by analog input (terminal 1)
● Torque command is given by voltage (current) input to terminal 1.
● When torque command is input from terminal 1, set "4 or 3" in Pr. 868 "Terminal 1 function
assignment".
● Torque command by analog input can be calibrated using calibration parameter C16
(Pr. 919) to C19 (Pr. 920). (Refer to section 6.20.6.)
