Online auto tuning (Pr. 95)
(2) Pr. 95 = "2" (normal tuning)/adaptive magnetic flux observer
This function is effective for torque accuracy improvement when using the motor with encoder.
The current flowing in the motor and the inverter output voltage are used to estimate/observe the magnetic flux in
the motor.
The magnetic flux of the motor is always detected with high accuracy so that excellent characteristics are provided
regardless of the change in the temperature of the secondary resistance.
Set "2" when exercising vector control wtih encoder.
CAUTION
1. Adaptive magnetic flux observer (Pr. 95 = "2") is invalid under vector control without encoder. Select
start time tuning.
REMARKS
1. Online auto tuning of the start time tuning is not enabled when the starting conditions of the inverter are not satisfied, e.g.
the MRS is input, the preset speed is less than the starting speed (Pr. 13), during inverter error, etc.
2. Online auto tuning of the start time tuning does not operate during deceleration or at a restart during DC brake operation.
3. Invalid for jog operation.
4. The RUN signal is not output during online auto tuning of the start time tuning. The RUN signal turns on at a start.
5. If the period from an inverter stop to a restart is within 4s, online auto tuning of the start time tuning is performed but the
tuning results are not reflected.
6. Automatic restart after instantaneous power failure overrides when automatic restart after instantaneous power failure is
selected.
7. Zero current detection and output current detection are valid during online auto tuning.
