Part Number: DRV8462 Hi Team,
The customer use SPI to drive two-step motors with up to 1ms sending two pulses.
When three pulses are sent in 1ms, the motor speed is slower than the two pulses (SPI uses a baud rate of 1M or 8M and does not reach the maximum…
Part Number: DRV8462 Hi Team,
How to drive the motor when using the HW interface? How to control the running current and holding current like the spi interface?
Regards,
Annie
Part Number: DRV8462 Hello, I am using DRV8462 to control stepper motors DINGS 17E2115AB4-69SNSN-130.
The supply voltage is 24V. I use physical STEP and DIR pins and control other registers via SPI. The motors run with full step and automatic 1/32 microstep…
Part Number: DRV8462 I use DRV8462 to design our precision motion control system. it is working well. the only issue is Customizable micro-stepping.
I load the customized number into register 0x17-0x1E.
when I set EN_CUSTOM to 0
if write 0xFA into register…
Part Number: DRV8462 Dear experts,
While analyzing the DRV8462-Q1 it is clear that it has a wide array of useful features. However, one of the main constraints in the design we are working on is the IC's ability to withstand the harsh environment in low…
Part Number: DRV8462 Hello,
I would like to use the DRV8462 driver for a stepper motor with a step angle of 7.5 degrees and be able to hold its position using microstepping, for example, keeping the motor at 10 degrees.
Is it possible to achieve this…
Hi Chris,
Thanks for the update and closing this thread. At 2000 RPM back EMF is the major deterrent. Not only to be able run without stalling but also to generate torque to address the work load. Motors with lower back EMF constant fare well. Else you…
Part Number: DRV8462 Hi Team,
When STEP inputs a low-frequency signal, the motor operates normally. When STEP increases to a certain frequency, the motor will not be able to rotate and will make noise. Would you help to check it?
Best regards,
Annie …
Part Number: DRV8462 Hello, I am using DRV8462 to control stepper motors. I use stand still power saving, automatic torque and stall detection. I previously used this controller to control motors with a fixed microstep, but I want to change it to automatic…
Part Number: DRV8462 Hi
I'm not interested in Auto Torque mode of the DRV8462 but would like to use ATQ_CNT to measure the load torque, similar with the current of a brushed motor.I made some measurements of ATQ_CNT with different load torque, supply…
