• To enable the control method and the control mode selected in Pr.800 (Pr.451), the condition to start operation must be
satisfied as shown in the following table. Otherwise the operation does not start due to the setting error (SE) alarm when
the start signal is input.

*1 The control method depends on the motor selected in Pr.71 (Pr.450): Real sensorless vector control for the induction motor, and PM sensorless
vector control for the PM motor.
*2 Operation can start regardless of the setting.
*3 A Vector control compatible option is required.
 Automatic parameter setting by changing the Pr.800 setting
• The Pr.10 and Pr.22 settings are automatically changed when the control method is changed.
• When the control method is changed from V/F control or Advanced magnetic flux vector control to Vector control, the Pr.10
setting is automatically changed as follows.
Pr. Setting value before change
10 3 Hz (initial value)
• When the control method is changed from Vector control to V/F control or Advanced magnetic flux vector control, the Pr.10
setting is automatically changed as follows.
Pr. Setting value before change
10 0.5 Hz
• When the control method is changed from V/F control or Advanced magnetic flux vector control to Real sensorless vector
control or Vector control, the Pr.22 setting is automatically changed as follows (only for the ND rating in the FR-E820-
0175(3.7K) or lower, FR-E840-0095(3.7K) or lower, FR-E860-0061(3.7K) or lower, and FR-E820S-0110(2.2K) or lower).

• When the control method is changed from Real sensorless vector control or Vector control to V/F control or Advanced
magnetic flux vector control, the Pr.22 setting is automatically changed as follows (only for the ND rating in the FR-E820-
0175(3.7K) or lower, FR-E840-0095(3.7K) or lower, FR-E860-0061(3.7K) or lower, and FR-E820S-0110(2.2K) or lower).
