Mitsubishi Electric FR-A820-00046 Instruction Manual page 267

Parameters
Vector control test operation, PM sensorless vector control test operation (Pr. 800 = "9, 109"")
Test operation in the speed control is available without connecting a motor.
The speed calculation changes to track the speed command, and such speed changes can be checked
on the operation panel or by outputting it as analog signals to the terminal FM, AM, or CA.
NOTES Since current is not detected and voltage is not output, monitors related to current and voltage
such as output current and output voltage, etc. and output signals do not function.
For speed calculation, speed is calculated in consideration of Pr. 880 "Load inertia ratio".
Since current synchronization operation occurs during PM sensorless vector control, the output
frequency becomes the same value as the command frequency.
