 Using a PM motor
Operating procedure
1.
Set the applied encoder (Pr.359 (Pr.852), Pr.369 (Pr.851)).
Refer to
2.
Set the applied 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 and Pr.725 as required.
3.
Select Vector control (speed control). (Refer to
4.
Perform offline auto tuning and encoder position tuning (Pr.96). (Refer to
Set Pr.96, and perform tuning.
5.
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, Vector control for the PM
motor with an encoder is enabled.
"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
6.
Perform the test operation.
NOTE
• For PM motors, after performing offline auto tuning and encoder position tuning, first perform PM parameter initialization. If
parameter initialization is performed after setting other parameters, some of those parameters are initialized too. (Refer to
page 231
Downloaded from ManualsNet.com
page 94 and set the parameters according to the option and the encoder to be used.
