Because the chopper isn’t lowering the current at all, can anybody explain how to do this? Tutti i marchi riportati sono detenuti dai legittimi proprietari. As usual, the maximum level of the voltage as input is limited by the positive regulator 5V therefore, in this case, the voltage is lowered by a zener and a npn transistor tip41c before the input of the regulator. I found one error 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. Another go with the oscilloscope shows that pin 1 on both ‘s now switch between 0 and 15volts, but pin 3 switches between 0 and 5 volts i can hear a small ticking sound from the motor when im jogging but it doesn’t move. The current minimum payable is approximately mA and with this range of current deck covers all the needs of cnc amateur pilot and industrial.

The schematic is very traditional and efficient.

Because the chopper isn’t lowering the current at all, can anybody explain how to do this? Sapevo to have suitable bridges to drive cnc small size and now it is time to move on to something more powerful and funzionale.

Problems with stepper driver (L and L)

On the base of the bridge is a trimmer and next to it a measure called Vref.

Follow us on All times are GMT It employs two integrated L that each pilot phase and a L which is responsible for the translation of step and implements the chopper. Originally Posted by MagooT.

To adjust the tension of course need a multimeter connected between mass and a measure Vref with a screwdriver and adjust the trimmer on the basis that you want to get on the engine.

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 i don’t think that’s the problem.

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. Do you have this problem?

Who Is Online 5. The VRef must be regulated according to this simple formula: Note that the resistance of sense l927 this l62033 with a total resistance of 0.

Hi Magoot, I made similar driver. My 10 ohm resistor is always get to smoke because of excess heat. I even built a whole cnc funzionante.

Any ideas what to look for would be nice, since i have no idea what might be wrong with this. Thanks for your help. The max level of voltage can be considered around 40V.

Results 1 to 12 of When i measure between GND and motor outputs M1-M4 i just see a blinking line at 10 volts on the oscilloscope.
