Default
P00.00
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 VFD to perform motor parameter autotuning
first.

P00.15
Motor parameter
autotuning
0: No operation
1: Rotary autotuning.
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.
3: Static autotuning 2 (partial autotuning); when the
present motor is motor 1, only P02.06, P02.07 and
0
