Parameters Speed control under Real sensorless vector control, vector control, PM sensorless vector control
FR-A800 5 - 81
5.3.2 Setting procedure of vector control (speed control)
Fig. 5-11: Setting procedure of vector control (speed control)
NOTES The speed command setting range under vector control is 0 to 400 Hz.
The carrier frequency is limited during vector control. (Refer to page 5-222.)
For vector control for a motor with a resolver, refer to the Instruction Manual of the FR-A8APR.
