Parameter
Switching the control method from the external terminal (MC signal)
● When "12 (2)" is set in Pr. 800 (Pr. 451 ), speed control is selected when the control mode
switching signal (MC) is off, and torque control is selected when the signal is off under real
sensorless vector control and vector control. Switching between speed control and torque
control is always enabled.
Under vector control, speed control/position control switchover and torque control/position
control switchover can be made by setting "4, 5" in Pr. 800. For the terminal used for MC
signal input, set "26" in any of Pr. 178 to Pr. 189 "Input terminal function selection" to assign
the function.
● When an analog input terminal (terminal 1,4) is used for torque limit, torque command, etc.,
terminal functions also switch as below if control mode is switched.
