Part Number: DRV8462 Other Parts Discussed in Thread: DRV8426 Hi,
I am having trouble with SPI communication with the DRV8426 - MODE and nSLEEP is HIGH.
SPI read command for FAULT register returns 1 for FAULT & SPI_ERROR - however the data packet seems…
Part Number: DRV8462 Hi,
Can someone please inform me what the response packets would look like for two devices (when daisy chained)? As possibly help me fix up why the received packets are different at the start as thought the status reply should start…
Part Number: DRV8462 Tool/software: Hello Ti,
Greetings of the day!
I designed a PCB to run Stepper Motor with DRV8462 Driver. Design Snap attached below.
I'm facing few major issues with it mentioned below:
With Manual Hardware Interface :
Even…
Part Number: DRV8462 Tool/software: Hi experts,
Good day!
My customer is using DRV8462 and encounter some issue regarding with 0x00 register. Every time to read 0x00, always read back 0xC0 value, which means are 1. I attached SPI logic as below. From…
Part Number: DRV8462 Hi there,
I'm developing a stepper driver with DRV8462DDWR Driver IC. In this regard I want isolation between motor supply and control signals including SPI Interface of Driver IC.
I have concern regarding the isolation between…
Part Number: DRV8462 The other parameters are:
ATQ_LRN_CONST1 = 75
ATQ_LRN_CONST2 = 52
ATQ_TRQ_MAX = 73
ATQ_TRQ_MIN = 66
ATQ_UL = 50
ATQ_LL = 10
With these parameters the motor always stalls, If I try to load KP, KD and ATQ_D_THR to…
Part Number: DRV8462 hi,
could you please give me a workflow for doing the auto torque learning routine?
Which registers have to be set with which parameters?
Could you give me a programm sequence about that?
Part Number: DRV8462 I am using the driver in spi mode. All pins are set accordingly to datasheet for working in SPI mode. SPI writes and reads normally the registers. I provide the step either by hardare pin or the software bit. In any case the problem…
Part Number: DRV8462EVM Other Parts Discussed in Thread: DRV8462 , Good day. I have two questions regarding the DRV8462 device. I have been testing the DRV8462EVM with a NEMA23 2A stepper motor.
The DRV8462 works very well with the motor, I am really impressed…
