Sensorless Vector Control Mode Settings for PM Synchronous
Motors
To operate a PM synchronous motor in sensorless vector control mode, set dr.09 (Control Mode) to
6 (PM Sensorless), select the motor capacity at dr.14 (Motor Capacity), and enter the nameplate
motor parameters in the Basic (bA) group. If a specific motor capacity does not exist in the setting
options, select the next higher motor capacity.
Code Input Values (Motor’s Rating Plate Information)
dr.18 Base Freq Base frequency
dr.20 Max Freq Maximum frequency
bA.11 Pole Number Motor pole number
bA.13 Rated Curr Rated current
bA.15 Motor Volt Motor rated voltage
bA.16 Efficiency Efficiency
bA.19 AC Input Volt Input power voltage
After entering the codes, set bA.20 (Auto tuning) to 7 [All(PM)] and perform a static auto tuning
operation. When auto tuning is complete, the bA.21 (Rs), bA.28 Ld (PM), bA. 29 Lq (PM), and bA. 30
(PM Flux Ref) parameters are automatically measured and saved. Note: when you select one of the
