Epsilon EP-I Indexing Drive and FM-2 Indexing Module Reference Manual

Tuning steps

If your Inertia Ratio is greater than 10 times the motor inertia, go directly to the Intermediate Level tuning.

No Tuning

No tuning will be required in most applications where the load inertia is 10 times the motor inertia or less.

Basic Level

Adjust Response to obtain the best performance.

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.Set the Line Voltage to the applied voltage (default is 230 Vac).

5.Leave all other tuning parameters at the initial values.

6.Enable the drive and run the system.

7.Adjust Response to obtain the best performance.

Fully Optimized Level

1.Determine the actual system parameters.

2.Disable the drive.

3.Enter the parameters.

4.Line Voltage set to the applied voltage (default is 230 Vac).

5.Enable the drive and run the system.

6.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.
