Running method by autotuning data
When running the inverter using the autotuning data:
1. A 0 : The control method is set at SLV (sensorless vector control).
2. A-98: The motor data is set on the autotuning side by the software switch.
Make the above two settings.
NOTE: When no torque is outputted during the sensorless vector run after the above settings are
made, make the following settings. Increase the setvalue ofRl ofeach remote operator
