autotune

[RuslanK]

Hello everyone.

I have ATV630D37N4. And I have motor 7.5 kW. And I want to autotune my frequency converter. But when I start to select engine power i am offered a range 11-55kW. How do I do autotuning in this case?

Every VSD has a range in which he works in a proper way. For a 37kW drive it is between 11 and 55kW. You want to use the VSD for a 7,5kW motor. This is out of the scope of this drive. Regarding to this point you are out of the scope of this drive. Neverless if you use U/F the motor should work. If you want to drive the motor in a most efficient way use the matching drive.
