2. Tuning Procedure
Stage 1
Quick Tuning
Setting the Inertia ratio and Optimizing Control Gain Set
The inertia ratio value is entered by the user if known or can be estimated as part
of autotuning. The control gain set will be automatically adjusted according to the
auto estimate of inertia ratio�
This method does not generate noise caused by any conflict between the inertia
ratio and the gain set�
