Hi
Thanks for using FixYa. Lr means locked rotor, this issue occurs due to locked rotors, you'll need to check the rotor wiring and windings. If the wiring is good and windings are not burnt then you'll need to replace your motor and motor control board. These are sold as one unit, it is a 3 phase motor and one of the phases is bad. A little power surge can damage the boards. Please rate the solution if the issue is resolved else post a comment for further assistance.
Thanks
