Any ideas what to look for would be nice, since i have no idea what might be wrong with this. Electronics for CNC apparates.
On the base of the bridge is a trimmer and next to it a measure called Vref. Product is in design stage Target: Ed behold the birth of the bridge that I present here. Not Recommended for New Design.

Sapevo to have suitable bridges to drive cnc small size and now it is time to move on to something more powerful and funzionale. Media Subscription Media Contacts.
The schematic is very traditional and efficient.
motir My 10 ohm resistor is always get to smoke because of excess heat. The time now is This ic can provide a higher current upto 5A therefore it is possible the use of bigger motors or, using the same motors, obtain a reduction of the heat generated.

I have fixed the problem now but it still won’t run. Since i can’t find anything wierd on the board, i’m asking if anyone can spot any errors in the schematic or board layout, i have checked the board about 10 times for solder bridges or stuff like that so steppsr don’t think that’s the problem.
The max level of voltage can mohor considered around 40V. Product is in volume production 3. Originally Posted by MagooT.

Because the chopper isn’t lowering the current at all, can anybody explain how to do this?
Selectors Simulators and Models. The trimmer is used to adjust the voltage reference comparator of L and accordingly adjust the current flowing in the phases of the engine. Tags for this Thread askingflickeringlook.

The VRef must be regulated according to this simple formula: I have measured about every pin using my oscilloscope but the only strange thing i found is that the outputs of the L’s pin 1 and pin 3 are high all the time, when i step it slowly using jog in Mach3 i can see some small flickering around volt, but i assume it should switch between high and low.
