Control Method Settings

Autotuning methods depend on the control method set for the Inverter. Make the settings as required by the
control method used.
Control Method Selection
Either of the following two control methods can be selected.

Turning on the Medium-voltage Power Supply
Items to be checked before turning on the medium-voltage power supply:
Confirm that the medium-voltage power supply is the correct voltage.
•
Confirm that the Inverter main circuit terminals (input terminals R, S, and T and output terminals U, V, and
•
W) are correctly connected.
Make sure that the motor is not connected to a mechanical system (No-load status).
•
Items to be checked after turning on the medium voltage power supply:
Measure the input voltage of each power cell.
•
If the input voltage exceeds the power cell rated input voltage of 630 VAC, switch the transformer tap set-
ting for main circuit and recheck the input voltage.
Use the Digital Operator to confirm input power supply voltage U1-90.
•
Confirm that the Digital Operator displays the Inverter as being in normal status.
