Detailed parameter description
Default
value
P00.00
Speed control mode
0: SVC 0 - Sensorless Vector Control mode
0
1: SVC 1 - Sensorless Vector Control mode
1 (recommended SVC mode)
2: V/F (SVPWM) - Sensorless Vector Pulse
Width Modulation
3: VC - Vector Control
Note: If 0, 1 or 3 is selected, it is required
to carry out motor parameter autotuning
first.

Motor parameter
autotuning
0: No operation
1: Rotary autotuning; carry out
comprehensive motor parameter
autotuning; rotary autotuning is used in
cases where high control precision is
required;
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) ;
