How to do identification run or ID run for Siemens G120 drive -
The purpose of the motor ID run is to allow the VFD to create a motor model in its memory that it can consult for % of nameplate torque and motor shaft speed. To determine shaft speed, a good motor model will need to know exactly how much slip occurs for each ft-lb or torque in the shaft, the motor rotor inertia, as well as correct motor nameplate data. Without this model, the VFD sensorless vector performance would be worse than if you had left it in V/hz mode
