Operating Procedure
(1) Set motor parameter selection H002 to "02" (online auto-tuning enabled).
(Set auto-tuning selection H001 to "00" (disabled).)
(2) Turn on the RUN command. (The Inverter automatically performs online auto-tuning during
stop.)
Secondary Resistance Compensation Function (Temperature
Compensation)
•This function compensates for speed fluctuations resulting from motor temperature changes, when
"sensorless vector control", "0-Hz sensorless vector control", or "sensor vector control" is selected
as the control method.
To use this function, set thermistor selection b098 to "02" (NTC).
(With other thermistors and settings, the motor temperature cannot be detected correctly.)
