Changing The Control Method And Mode - Mitsubishi Electric 800 Series Instruction Manual (Function

4.2

Changing the control method and mode

Set the control method and the control mode.
V/F control, Advanced magnetic flux vector control, Real sensorless vector control, Vector control, and PM sensorless vector
control are available.
The available control modes are speed control, torque control, and position control modes.
• Select a control method and a control mode by setting Pr.800 (Pr.451) Control method selection.
• The control mode can be switched using a mode switching signal (MC).

*1 The setting range for the 575 V class is "0, 3, 5, 6, 10, 13, 15, 16, 30, 33, 8090, 8093, 9090, and 9093".
*2 The initial value differs according to the inverter's voltage class (200/400/575 V).
*3 The inverter internal data is used under PM sensorless vector control.
 Setting the motor capacity and the number of motor poles (Pr.80, Pr.81)
• Motor specifications (the motor capacity and the number of motor poles) must be set to select Advanced magnetic flux
vector control, Real sensorless vector control, Vector control, or PM sensorless vector control.
• Set the motor capacity (kW) in Pr.80 Motor capacity and set the number of motor poles in Pr.81 Number of motor poles.
 Selection of the control method and the control mode
• Select a control method (and a control mode) from V/F control, Advanced magnetic flux vector control (speed control), Real
sensorless vector control (speed control, torque control), Vector control (speed control, torque control, position control),
and PM sensorless vector control (speed control).
