Setting Procedure Of Vector Control For Motor With Encoder - Mitsubishi Electric FR-A820-00046 Instruction Manual

6.2

Setting procedure of vector control for motor with encoder

Follow the following procedure to change the setting for the vector control for the motor with an encoder.
Set the applied encoder. (Pr.359, Pr.369)
Set Pr.359 Encoder rotation direction and Pr.369 Number of encoder pulses according to the encoder to
be used.
Set the motor. (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, Pr.84)
Set Pr.71 Applied motor, Pr.9 Rated motor current, Pr.80 Motor capacity, Pr.81 Number of motor poles,
Pr.83 Rated motor voltage, and Pr.84 Rated motor frequency according to the motor specifications.
(Setting "9999 (initial value)" in Pr.80 or Pr.81 selects V/F control.)
Set Pr.702, Pr.706, Pr.707, Pr.724, or Pr.725 as required for the PM motor.
Select vector control (other than position control). (Refer to
Perform offline auto tuning for induction motors, or perform offline auto tuning and the encoder position
tuning for PM motors. (Pr.96) (Refer to
Set Pr.96, and perform tuning.

motor
Configure the initial parameter setting for the applied motor using Pr.998.
When the setting for the PM motor is selected in Pr.998 PM parameter initialization, the vector control for the
motor with an encoder is selected.
"8009": Parameter (rotations per minute) settings for an IPM motor other than MM-CF
"8109": Parameter (frequency) settings for an IPM motor other than MM-CF
"9009": Parameter (rotations per minute) settings for an SPM motor
"9109": Parameter (frequency) settings for an SPM motor
Under position control
