6-2-3 Auto-tuning of Motor Parameters
• Use this function to measure and automatically set the motor parameters required for the sensorless
vector control, 0-Hz sensorless vector control, or sensor vector control.
• To use the sensorless vector control, 0-Hz sensorless vector control, or sensor vector control
method, perform offline auto-tuning to measure the motor parameter values.
• The offline auto-tuning function is applicable to the 1st and 2nd control methods only. It cannot be
used for the 3rd control method.
• The measured motor parameter values will be set as 50-Hz data for one phase in 3-phase
Y-connection.
