6-1-2 Offline Auto-tuning for Motor Parameters
• Use this function to measure and automatically set the motor parameters required for sensorless
vector control.
• To use the sensorless vector control method, perform auto-tuning to measure the motor parameter
values.
• The measured motor parameter values will be set as 50-Hz converted data for one phase in Y-con-
nection.
