To achieve proper installation and correct operation of the encoder a software is expressly developed and released by Lika Electronic. It allows the operator to set up and calibrate the AMM8A modular encoder during installation. The program is supplied for free and can be installed in any PC fitted with a Windows operating system (Windows XP or later).
