The DRV8825 also features a FAULT output that drives LOW whenever the H-bridge FETs are disabled as the result of over-current protection or thermal shutdown. Actually the Fault pin is shorted to SLEEP pin so, whenever the Fault pin is driven LOW, the whole chip is disabled. And it remains disabled until either RESET, or Motor Voltage VMOT is removed and reapplied. Output. FLT = Fault. Das ist ein Ausgang! Der einzige Grund weshalb man da High anschließen kann ist dass der Pin einen 1,5k Schutzwiderstand hat und über 10k mit Sleep verbunden ist. Das geht also, aber mach die 5V besser an Sleep. Dann ist klar was gemeint ist The DRV8825 also features a FAULT output that drives low whenever the H-bridge FETs are disabled as the result of over-current protection or thermal shutdown. Otherwise, the pin is floating, so you will need to use a pull-up resistor to give it a default high state if you want to use this pin. Note that there is a 1.5k protection resistor in series with the pin that you should take into.

So why is the FAULT low? According to the DRV8825 datasheed this scenario means that there is something wrong with the controller chip. It's not overvoltage, and it can't be overheating (board chip was cool to the touch). From the looks of the board schematics I understand the FAULT pin has a 10K resistor connected to the SLEEP pin. So. FAULT LOW when the stepper driver is in fault condition. You can provide 5V on this pin for compatibility with stepstick A4988 * this is the default state when the pin is not connected Stepstick DRV8825 Datasheet - Reprapworld.com 5.

The configuration pins (M0-M2 for microstepping selection, Enable, Reset and Sleep) are shared between the two DRV8825 boards - so both have to be active at the same time and both have to use the same microstepping settings. Step and Direction are of course not shared as well as the Fault outputs that signal overcurrent or thermal shutdown of the drivers I've used a 4K7 resistor from /Fault pin to /Sleep pin (which is connected to /Reset in my board). According to the specs the /Fault output is connected through a resistor to the pin, so that output is not damaged when connected to +5v.

Free Next Day Delivery The trouble comes from the RESET-SLEEP wiring to the 5v nano pin i think If i understood correctly this will bring logical supply to the driver from the arduino. I tried two ways, RESET-SLEEP shorted and connected directly to 5v And, reading Pololu page about the driver, i also tried to short SLEEP-RESET but connect FAULT to 5v on nano. I've also tried with ENABLE disconnected as Pololu says. In summary, the DRV8825 carrier is similar enough to our A4988 carriers that the minimum connection diagram for the A4988 is a valid alternate way to connect the DRV8825 to a microcontroller as well:The SLEEP pin on the DRV8825 is not pulled up by default like it is on the A4988, but the carrier board does connect it to the FAULT pin through a 10k resistor. Therefore, systems intended for the. El pin para alimentar la parte digital del A4988, se usa como salida FAULT en el DRV8825. Sí, el DRV8825 sabe cuando ha ocurrido un fallo, pero el Marlin no está preparado para hacer nada al respecto (al menos, que yo sepa)

Specification: Engraver CNC Shield Board Version: 3.0 Voltage: DC 12~36V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board) Size: approx. 68 x 53 x 18mm (L*W*H) Color: Red A4988 Stepper Motor Driver Thermal shutdown circuitry: Yes Crossover-current protection: Yes Ground fault protection: Yes Load short-circuit. Il pin ENABLE serve ad abilitare o disabilitare le uscite dei FET che pilotano il motore. Se impostato ad un valore alto, le uscite saranno disabilitate, ovvero il motore verrà rilasciato. Se impostato ad un valore logico basso, le uscite saranno attivate. Questo pin gestisce soltanto le uscite relative al motore. Indipendentemente dal suo stato, il resto dell'elettronica rimarrà attivo.
