Hello! I faced problem I can not find on Internet.

Fadal VMC40 Model 904-1
Seller told it is build on 1986. Software says 1993.

Worked fine before move.
Now wont ask for belt position on start.
Asks to jog axes to home position, but Jog screen returns back almost immediately. Jog wheel does nothing.
Responds with "Reset the emergency stop switch" to CS command.
Emergency switch is off. No breakers with popped up buttons. Motor breaker with big white "button" also is on.
I can not reset emergency switch by pressing Jog button, because it works improperly.

Connected to 220V 3 phase. Pressure connected too.

Here is the videos:

...if, the control is asking for Backlash numbers at startup after power loss from the move...you have a dead CMOS Battery mostly likely.

Watched the videos that pendant is the original and it does not have all of the Switches on the pendant that the Newer ones has. So try going to SETP on page 1 the under PENDANT you must select KeyBoard Beside the Monitor option should be 1. Try that

It looks like your CPU battery died and you lost your parameters. You'll need to pull the CPU card out of the electrical cabinet, and check the 3.6V lithium (AA sized battery) for voltage. If you don't have 3.6V you'll need to replace it. Batteries Plus sells the battery with leads for around $11 around me, de-solder the old battery, and solder on a new, then you'll need to do a zero memory procedure and re-set all your machine parameters.
