Description
Default
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: To select 0, 1, or 3 as the control mode, enable
the VFD to perform motor parameter autotuning first.

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.
3: Static autotuning 2 (partial autotuning); when the
present motor is motor 1, only P02.06, P02.07 and
P02.08 are autotuned; when the present motor is
motor 2, only P12.06, P12.07 and P12.08 are
autotuned.
