Control mode
(5) 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.
Terminal 1 function according to control
