Remark
1. If satisfactory performance through auto-tuning cannot be fully obtained,
please adjust the motor constants for the observed symptoms according to the
table below.
2. If the inverter capacity is more than twice the capacity of the motor in use,
the inverter may not achieve its full performance specifications.
3. Running multiple motor under sensorless vector control is not available.
4. When DC braking is enabled, the motor constant will not be accurately set.
Therefore, disable DC braking before starting the auto-tuning procedure.
5. The motor will rotate up to 80% of base frequency : make sure that accele-
ration or deceleration is not operated. If then, decrease the manual torque
boost setting value.
6. Be sure if motor is in standstill before you carry out an auto-tuning.
Auto-tuning data carried out when motor is still running may be not correct.
7. If the auto-tuning procedure is interrupted by the stop command, the auto-
tuning constants may be stored in the inverter. It will be necessary to store
the inverters factory defaults setting.
