Parameters
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.
The operation for the setting of "10 or 110" is performed when "13, 14, 113, or 114" is set.
The operation for the setting of "20 or 110" is performed when a value other than "9, 13, 14, 109,
113, or 114" is set.
The operation for the setting of "20 or 110" is performed when a value other than "13, 14, 113, 114,
or 9999" is set.
The operation for the setting of "20 or 110" is performed when a value other than "9 or 109" is set.
The operation for the setting of "20 or 110" is performed when a value other than "9999" is set.
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 = "any of 100 to 106 or 109 to 114" selects the fast-response operation. The fast-re-
sponse operation 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.
