Commissioning
The position tracking of the measuring gear can be activated in the drive wizard (STARTER)
during the configuration of the drive. During the configuration there is an item for encoder
parameterization. In the encoder dialog, click on the "Details" button and activate the
checkbox for position tracking in the displayed dialog.
The parameters p412 (Measuring gear, rotary absolute encoder, revolutions, virtual) and
p413 (Measuring gear, position tracking tolerance window) can only be set via the expert list.
Requirements
● Absolute encoder
● Firmware version ≥ V2.4
● CU310 or CU320 with Order No. 6SL3040- ....- 0AA1 and Version C or higher
Function diagrams (see SINAMICS S120/S150 List Manual)
