 Changing the control mode with external terminals (MC signal)
• To use ON/OFF of the MC signal to switch the control mode, set Pr.800 or Pr.451. Refer to the FR-E800 Instruction Manual
(Function) and set Pr.800 or Pr.451. To input the MC signal, set "26" in any parameter from Pr.178 to Pr.189, or Pr.525 to
Pr.531 (Input terminal function selection) to assign the function.
• When an analog input terminal (terminal 1) is used for auxiliary speed setting or torque limit, switching of the control mode
changes the terminal function as follows:
Speed control / torque control switchover
