Self-commissioning controller for field-oriented elevator motor/drive system

A self-commissioning controller 7 for a field-oriented elevator motor controller 14 includes calculating an integral gain KI, a proportional gain Kp, and an overall gain (Gc) for the motor controller; obtaining initial values of a rotor time constant tau R, magnetizing current Id, and motor torque constant KT for the motor controller 14, and obtaining a value of a motor transient inductance L sigma ; calculating final values for said rotor time constant tau R and magnetizing current Id, using said transient inductance L sigma ; and calculating a system inertia J* parameter for speed loop compensation 16 within the motor controller 14. The controller 7 may also include calculating the initial values for tau R, Id, and KT*, and performing self-commissioning automatically upon receiving a command from a service tool 80.
