How can you get the ATV11 unit to run as soon as power it up with no voltage or current speed reference present?

You need to confirm in the application function menu FUn that code tCC  then sub code ACt is set to 2C which is 2-wire control.

Then need to confirm in sub menu tCt that type of two wire control is set for LEL which allows the unit to start the motor when forward or reverse input is high when the drive controller is powered up and a speed reference is present.

You can then jumper 15v to LI and the unit will run at LSP (under 1st level parameters) low speed when power is applied to it.
