Can the ATV66 be run without a motor connected or with a motor whose power rating is less than 45% of the controller`s output rating?

Yes, go to menu 7.4, Fault Mangement, and turn Output Phase Fault (Out. Phase Flt) to NO. This will not disable the drive`s overloads.

If a motor whose power rating is less than 45% of the controller`s output rating is going to be run like this under normal operating conditions, then an external overload must be supplied as it it below the controller`s minimum overload setting.
