F10.30~F10.31 is the PI parameter used for weak magnetic regulation, and F10.32 is used to limit
the PI output of weak magnetic regulation.

F10.33 ~ f10.35 are used for the current compensation when the synchronous motor starts. If it is
difficult to start the synchronous motor, the frequency compensation point can be adjusted properly.
F10.36 ~ f10.37 are used for speed estimation of synchronous motor. If there is sound in the
spindle when the synchronous motor is running, these two parameters can be adjusted
properly.

During acceleration and deceleration, if output current exceeds current limit (F11.01), inverter
stops acceleration/deceleration and remains at present running frequency, and will
accelerate/decelerate as per previous acceleration/deceleration time after output current decreased.
During steady state, after output current exceeds the current limit (F11.01), inverter decelerates
as per the decreasing time (F11.02) of constant speed current frequency, and the minimum
deceleration could reach lower limit frequency (F01.10). After output current decreases, inverterwill
accelerate to setting frequency as per setting acceleration time, see Figure 6-19.
