Part Number: DRV8462 Other Parts Discussed in Thread: TIDA-00210 , DRV8962 , DRV8262 We're developing a stepper motor driver using the Texas Instruments DRV8462 (DDV package). We encountered some issues during testing. When driving the motor in Smart…
Part Number: DRV8462 Tool/software: Hii,
We are facing a problem using to DRV8462 DDWR.
When we connect VM pins to +24v immediately ic burnt out hardware is designed accordingly to provided circuit in ic pdf.
Please help us to come out this…
Part Number: DRV8462 Tool/software: Hi,
we are facing a problem using DRV8462
when we connect VM pins to +24v, immediately IC burnt out.
hardware design is according to provided circuit in IC PDF.
Part Number: DRV8462 I am using the driver to drive a stepper motor sanyo denki 4 A .
I am able to reach the 1500 rpm in 2 seconds. I am doing a s curve ramp and i have configured the driver with spi. Do you think i am reach 2200 rpm in less of 1…
Part Number: DRV8462 Tool/software: The chip is attached to the bottom surface of the PCB , with its heat dissipation surface fitting snugly against the surface of the heat sink's boss for heat dissipation. The heat sink is connected to the bottom surface…
Part Number: DRV8462 Tool/software: I've been reading the manual of RV8426 again these two days. Regarding the automatic torque section, the red box is my personal understanding of the value of ATQ_LRN_MIN_CURRENT. Could you please check if it's like…
Part Number: DRV8462 he DRV8462 motor driver chip reported an error after power-on. After reading the register, it was found that the charge pump was under-voltage. The actual measurement confirmed that the voltage of the charge pump was indeed low. What…
Part Number: DRV8462EVM Other Parts Discussed in Thread: DRV8462 , , DRV8462VEVM Hi,
currently tryn to setup the auto torque learning routine on my custom board for the DRV8462 and i encountered massive different parameters for both constants after…
Part Number: DRV8462 Tool/software: We first measured the peak to peak value of the A+phase output current through HW mode to be 10.0A; Using SPI mode, enable the automatic torque function, configure the ATQ_CTRL12 register to 0xFF, and measure the peak…
Part Number: DRV8462 Tool/software: Hi team,
We are considering using it for motors with various current values.
Will the accuracy of 1A change if the full scale is set to 10A or 3A?
Considering full scale, 1A when set to 3A is 33%, and 1A at 10A…
