Main circuit undervoltage
drive
Meaning: The following conditions apply when no run command is input (the regenerative converter is stopped): The main circuit DC voltage is below the setting of L2-05 (main circuit undervoltage (Uv) detection level). The magnetic contactor for inrush current control inside the regenerative converter is open. The control power is in an undervoltage condition.
Possible causes
- Input power supply phase loss occurs.

Main circuit undervoltage
drive
Meaning: The following conditions occur when no run command is input (regenerative unit stopped): The main circuit DC voltage is below the setting of L2-05 (main circuit undervoltage (Uv) detection threshold); the electromagnetic contactor for inrush current control inside the regenerative unit is open; the control power is in an undervoltage condition.
Possible causes
- Input power supply phase loss occurs.
