Page 8: Preliminary Information
The parametrization and set up of the HM58 PY-PN programmable encoder is achieved through a software expressly developed and released by Lika Electronic. The program is supplied for free and can be installed in any PC fitted with a Windows operating system (Windows XP or later). It allows the operator to set the working parameters of the device and monitor whether the device is running properly. -
