FM-3 Programming Module Reference Manual

Tuning Procedure

Once the initial setup has been completed, you can run the system to determine if the level of

tuning is adequate for the application. There are basically four levels of tuning for a drive.

• No Tuning

• Basic Level

• Intermediate Level

• Fully Optimized Level

Each level is slightly more involved than the previous one requiring you to enter more

information. If your system needs optimization, we recommend that you start with the Basic

Level, then determine if further tuning is needed based on axis performance.

The setup procedures explained here assume that you are using EMERSON Motion Control

PowerTools® FM-3 software or an FM-P.

Initial settings

Set the drive tuning parameters as follows:

• Inertia Ratio = 0

• Friction = 0

• Response = 50

• High Performance Gains = Enabled

• Feedforwards = Disabled

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.
