Solutions
By setting devices of MR Configurator2 machine failure prediction function to numerical display objects
of GT Works3, you can predict deterioration of the servo amplifier drive parts by checking the GOT.
* The failure prediction function can be used on MR-J4-GF(-RJ) servo amplifier with the software version A3 or later. This
function does not guarantee prediction of all failures.
