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 any…
Part Number: DRV8462 Hi support team.
Is auto torque control affected by Decay mode setting? When I changed the initial value from Smarttune (Ripple control) to Mixed decay 60%, the current reduction effect of Autotorque became less noticeable. Do you…
Part Number: DRV8462 Hi team,
Could you please help estimate the expected power losses on the DRV8462? Could you please provide some data on this?
Besides thermal and switching losses, what other losses should I expect?
BR, Stefan
Part Number: DRV8462 Other Parts Discussed in Thread: , DRV8848 Hi Team,
1. Use the DRV8462 driver chip, set it to HW mode, subdivide it into 32, and send PWM waves with a frequency above 20khz. The motor has a sound but cannot rotate. When the same…
Part Number: DRV8462 Champs,
I noticed we added a silent step mode in DRV8462. In this mode we are using a PI controller to achieve a current close loop. This is well aligned with the trend we see in customer side, where they are try to achieve 'servo…
Part Number: DRV8462 The Datasheet recommends to apply less than 45 Newton. What is the recommended Force (for example 10 Newton)?

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?

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…
Part Number: DRV8462 Hi Team,
The customer uses the stepper motor driver built by DRV8462. After enabling, there is a slight jitter problem when there is no pulse (or no rotation). May I know how to resolve it?
In addition, the stepper motor remains…
Part Number: DRV8462 Hello,
I have an application where I need to drive two stepper motors. Both are 24V, 2.6A each. Is the DRV8462 a good solution for this? I assume that I will need one part per stepper motor correct?
Also, when is the DRV8462DDV…
