Application Precautions
The drive may fault on a control power supply fault (Uv2) if the UPS can’t provide enough voltage, or if the Light Load
Direction Search is not set properly. If this problem occurs, take the following corrective actions:
Corrective Action:
• Use a separate battery for the controller power supply.
• Use a battery with a voltage higher than 250 Vdc for 200 V class drives, 500 Vdc for 400 V class drives, or 720 Vdc for
600 V class drives and connect it to the control power supply input (CN19). Alternatively use a 24 Vdc battery and an
optional 24 V Backup Power Supply Unit.
• Enable Light Load Direction Search (S4-01 = 1).
