Control method
The setting values of 100 and above are used when the fast-response operation is selected.
Advanced magnetic flux vector control if a vector control compatible option is not installed.
For induction motors, the operation for the setting of Pr. 800 (Pr. 451) = "10 or 110", speed control
under Real sensorless vector control, is performed when Pr. 800 (Pr. 451) = "13, 14, 113, or 114".
For IPM motors (MM-CF), the operation for the setting of Pr. 800 (Pr. 451) = "20 or 110", speed control
under PM sensorless vector control, is performed when a value other than "9, 13, 14, 109, 113, 114,
or 9999" is set in Pr. 800 (Pr. 451).
For IPM/SPM motors (other than MM-CF), the operation for the setting of Pr. 800 (Pr. 451) = "20 or
110", speed control under PM sensorless vector control, is performed when a value other than "9,
109, or 9999" is set in Pr.800 (Pr.451).
V/F control when Pr. 80 or Pr. 81 is "9999", regardless of the Pr. 800 setting. When Pr. 71 is set to the
IPM motor MM-CF, PM sensorless vector control is enabled even if Pr. 80 ≠ "9999" or Pr. 81 = "9999".
Setting Pr. 788 (Pr. 747) = "0" (low-speed range torque characteristic disabled) selects speed control.
Selecting the fast-response operation (Pr. 800 (Pr. 451) = "100 to 106, 109 to 114")
Setting Pr. 800 = "100 to 106 or 109 to 114" selects the fast-response operation. The fast-response op-
eration is available during vector control, Real sensorless vector control, and PM sensorless vector
control.

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.
NOTES During fast-response operation, the carrier frequency is always 4 kHz. (Refer to page 237.)
E.THT is more likely to occur when fast-response operation is set at the SLD or LD rating.
