Is it one of the red emergency buttons that you have to turn and pull out to activate it.

Also make sure chuck guard is closed.

Turn off all the QF switches 1-6 and turn them back on

sometimes these trip without showing

after then we need a diagram

Those diagrams dont seem to be of your machine

theres no VFD for a start

Is yours single phase or 3 phase?

First check that you have 24 volts AC on the secondary of of the 24 volt control transformer. I think it is the one at the top right of the control box. I can't see the labels clearly so can you take a properly focused picture (Or pictures.) of the control box with your camera pointing straight at it. (Not looking down at an angle as in your picture in your first post.) If you have 24 volts on the output of the transformer then check if you have 24 volts AC across the coil of KM1. (This contactor should be closed except when the emergency stop button is pressed.)

If the circuit diagram is for your machine you have a problem as there should not be any switches between the vdf and the motor. The diagram indicated the vdf could be on the far left off the diagram.

i see two transformers in your photos what voltage are they, and what do they power? Trace the wires.

I suspect the vvdf is blown at its output. When converting my Bridgeport to vdf and 240 v a significant amount of fuses and other 3 phase junk had to be deleted. The vdf has adequate overload protection built in..

the main motor is now worked by a contractor which now sends the digital run signal to the vdf inputs and thus running the motor triggered by the normal push button latched with the same contractor

perhaps a separate mans lead direct to the vdf will test it, it should light up If it dies Its then up to you about risking starting the main motor .. do take care with this! It won’t start direct from the vdf itself as the parameters on it wil be set or remote operations

good luck

You will have to trace back the connections from the DRO and lamp I’m not sure on this, but they probably conn coed directly to the mains input. In the diagram they are driven from a transformer. What voltage is the lamp? Looks like 24 v

Did you get 24 volts AC on the secondary of the 24 volt control transformer and the coil of KM1 ?
I still cannot read the terminal labels on the contactors and circuit breakers or the markers on the ends of the cables.
If your camera has a macro mode you could photograph the individual contactors and circuit breakers. You could also use manual focus instead of auto focus.
