The troubleshooting manual says: The drive internal dc link voltage is too low, or the supply voltage is too low, or the supply has been lost, or a supply phase is missing.
To clear the undervoltage alarm you will need a voltmeter to verify all the required voltages and go from there...
You'll see the undervoltage alarm appear many times when an external 24V power supply or external 120V source is missing due to a tripped breaker or blown fuse.
