YASKAWA FSDrive-MV1S - Control Method Settings; Turning on the Medium Voltage Power Supply

Trial Operation Procedures
4-5
* The factory settings depend on the Inverter capacity.
 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.
