6.5.3 Intermediate Level
1. Calculate or estimate the load inertia. It is always better to estimate low.
2. Disable the drive.
3. Enter the inertia value calculated into the Inertia Ratio parameter.
4. Leave all other tuning parameters at the initial values.
5. Enable the drive and run the system.
6. Adjust Response to obtain the best performance.
6.5.4 Fully Optimized Level
1. Determine the actual system parameters.
2. Disable the drive.
3. Enter the parameters.
4. Enable the drive and run the system.
5. Adjust Response to obtain the best performance.
General Tuning Hints
General Tuning Procedure:
1. Calculate inertia of the system
The inertia of the system up to the motor shaft should be calculated using CT-Size software or some other inertia calculating software. Under
perfect mechanical conditions, entering this number into the “Inertia” parameter will produce a well-matched system tuning. Because most
systems include mechanics that are less than ideal, a number less than the inertia parameter will need to be used to avoid bandwidth issues or
“buzzing” of the motor. See Figures 144 and 145.
