L6203 STEPPER DRIVER

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. Implementing fast decay mode chopping using the L Product is in volume production. Electronics for CNC apparates. It employs two integrated L that each pilot phase and a L which is responsible for the translation of step and implements the chopper. Because the chopper isn’t lowering the current at all, can anybody explain how to do this? Results 1 to 12 of

Bipolar stepper controller using the couple L/L (Upto 5A) –

Do you have this problem? Nothing more to say, the schematic is very traditional and follows the directives of the application notes of the l62033 involved. General terms and conditions.

Communications Equipment, Computers and Peripherals. Product is in volume production.

I’m sorry, i don’t understand what you mean, i’m not good at reading schematics what does it do? Controlling voltage transients in full-bridge driver applications.

Note that the resistance of sense of this bridge with a total resistance of 0.

On the base of the bridge is a trimmer and next to it a measure called Vref. Thanks, i googled around a bit and read about vref, this is what i came up with: This is necessary because the maximum input tension level is limited to 20V for a 78L05 and V for a 78H05 but usually less and depends by the manifacturer. 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.
