2.10 Tuning the Position Loop

According to your drive type, you will now need to tune either the position loop or the

dual — position/velocity — loop. Tuning of the dual loop is described in section

2.11.

The procedure is very similar for both loops. The Wizard performs the test using point-

to-point (PTP) motions, according to the selected PTP motion and recording parameters.

The Composer records the PTP performance and compares it to the PTP trajectory.

The Composer Wizard enables you to perform position loop tuning in three modes:

 Manual tuning, in which you manually configure the position loop by entering each of

the required parameters.

 Automatic tuning, in which you select the level of fine tuning, and let the Composer

determine the needed parameters automatically.

 Advanced manual tuning, in which you create or modify a gain schedule table that

operates for a range of velocities.

When you select Step 4, Tuning Position Loop in the Establishing Commutation dialog

box or when you finish the Tuning Velocity Loop process, the Tuning Position Loop

dialog box is displayed as follows:

Select the tuning mode from the Step 1: Select Tuning Type drop down list.

2.10.1 Manually Tuning the Position Loop

1. From the Step 1: Select the Tuning Type drop-down list, select Manual Tuning. The

dialog box will remain with its default settings.

2. In the Step 2: Adjust Filter Parameters block, type the filter values required for

optimal step response in the KP (proportional gain), KI (integral gain) and KD

(derivative gain) text boxes.
