Setting of the elasticity-based pole position identification

The technique described in the following is an example of the setting of the elasticity-based pole

position identification (PolID) for linear motors and rotary motors.

● You can parameterize this technique in the commissioning tool.

● The following example shows the parameterization in STARTER.

Also observe the notes and information on this technique in Section "Supplementary conditions

(Page 151)".

The following requirements must be satisfied in order to be able to perform the elasticity-based

● Motor, encoder and brake control have been correctly parameterized.

Uncontrollable axis motion as a result of incorrect settings

With incorrect settings during the elasticity-based PolID, uncontrollable axis motion can occur

when enabling the axis after the measuring procedure, which can cause death or severe injury.

● Ensure that the settings in the context of this technique are correct.

● Ensure that after completing the technique, the axis cannot move.

Proceed as follows to set the elasticity-based PolID.

1. Open the STARTER commissioning tool.

2. Create a new project and select the components in accordance with your drive configuration.

Call the already saved project in which you want to perform the elasticity-based PolID.

3. Click the
