Parameter
Setting torque bias amount with terminal 1 (Pr. 840 = 3)
● C16 "Terminal 1 bias command (torque/magnetic flux)", C17 "Terminal 1 bias (torque/
magnetic flux)", C18 "Terminal 1 gain command (torque/magnetic flux)", C19 "Terminal 1
gain (torque/magnetic flux)", and Pr. 846 "Torque bias balance compensation" can be set
automatically according to the load.
● When torque command is set from terminal 1, set "6" in Pr. 868 "Terminal 1 function
assignment".
