Need Help!- mitsubishi loses positon after jog

[mrperfect]

mitsubishi meldas; if jogging machine using jog button or in handle mode for whatever reason and then running prog in auto or tape mode the control will lose itsprevious known position and it must then be homed again and reset this is very annoying and time consuming as sometimes it may take a number of times before it remembers where it is again.
when you home the machine after power up even tho all xyz axis home lights come on it can also likely not know its position and the start up procedure must be repeated sometimes numerous times
Note, the machine once set up having run a prog in the right place once is then 100% reliable and will not lose its position unless manually moved

It sounds like you have the Manual Absolute switch turned on. It may be a switch on your operation panel or a PLC switch on the screen somewhere.
