•This function calculates online auto-tuning data during offline auto-tuning. Even with a general-
purpose motor, perform offline auto-tuning once.
•After the motor is stopped, online auto-tuning is performed for 5 seconds max. (For tuning R1 and
R2, this function performs DC excitation once. The tuning result is not displayed.) If the RUN
command is input during this period, priority is given to the RUN command, and the online auto-
tuning is aborted. (The tuning result is not reflected.)
•With "DC injection braking during stop" selected, online auto-tuning starts after DC injection
braking is completed.
•If FOC and SON are allocated to terminals, online auto-tuning is not performed.
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.)
