current vector of the AM, and then decomposes the stator current vector into exciting current (current component that
generates internal magnet field) and torque current (current component that generates torque) based on field orientation
principle, and therefore controls the amplitude values and phase positions of the two components (namely, controls the
stator current vector of the AM) to realize decoupled control on exciting current and torque current, thus achieving
high-performance speed regulation of the AM.
The inverter unit uses the sensor-less vector control algorithm, which can be used to drive AMs and permanent-magnet
SMs simultaneously. As the core algorithm of vector control is based on accurate motor parameter models, the accuracy
of motor parameters affects vector control performance. It is recommended to enter accurate motor parameters and
autotune motor parameters before executing vector control.
As the vector control algorithm is complicated, exercise caution before modifying vector control function parameters.

Speed control mode
0: Sensorless vector control (SVC) mode 0
1: Sensorless vector control (SVC) mode 1
2: Space voltage vector control mode
3: Closed-loop vector control mode
Note: Before using a vector control mode (0, 1, or
3), enable the inverter unit to perform motor
parameter autotuning first.

P00.15
Motor parameter autotuning
0: No operation
1: Rotary autotuning 1.
Comprehensive motor parameter autotuning. It is
recommended to use rotating autotuning when high
control accuracy is needed.
2: Static autotuning 1 (comprehensive autotuning);
static autotuning 1 is used in cases where the motor
cannot be disconnected from load.
