Setting the applied motor
• Refer to the following list and set the parameters according to the applied motor.
 The setting is available for FR-A820-00630(11K) or lower.
 For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower.
 For the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher.
 The same operation is performed for the both settings.
