COMMONLY USED CONFIGURATIONS
When Cn.46 is set to 1 (Angle Detect), the motor is operated according to
the pole position detected by changes in the current. The voltage pulse
input is used to detect the pole position and it results in a small amount of
noise at motor startup.
When Cn. 46 is set to 2 (Alignment), the drive forcefully align the rotor
position by supplying DC current for a certain period of time.

6. Voltage compensation
These parameters set the output compensation values during a PM
synchronous motor operation in sensorless vector control mode.
If the motor fails operating at low speeds, at or below 5% of the rated motor
speed, increase the parameter values set at Cn.39 and Cn.40 by 10%
increments. Decrease the values in 10% decrements if a clanking noise
occurs at motor startup and motor stop.
