AMIS-30623 LIN Microstepping Motordriver  
Data Sheet  
Motion detection is disabled when the RAM registers AbsThr[3:0] and DelThr[3:0] are empty or zero. Both levels can be programmed  
using the LIN command SetStallParam in the registers AbsThr[3:0] and DelThr[3:0]. Also in the OTP register AbsThr[3:0] and  
DelThr[3:0] can be set using the LIN command SetOTPParam. These values are copied in the RAM registers during power on reset.

MinSamples  
MinSamples[2:0] is a Bemf sampling delay time expressed in number of PWM cycles, for more information please refer to the white

FS2StallEn  
If AbsThr or DelThr <>0 (i.e. motion detection is enabled), then stall detection will be activated AFTER the acceleration ramp + an  
additional number of full-steps, according to the following table :

For more information please refer to the white paper “Robust Motion Control with AMIS-3062x Stepper Motor Drivers”,  
DC100SDis  
When a motor with large bemf is operated at high speed and low supply voltage, then the PWM duty cycle can be as high as 100%.  
This indicates that the supply is too low to generate the required torque and might also result in erroneously triggering the stall  
detection. The bit “DC100SDis” disables stall detection when duty cycle is 100%. For more information please refer to the white paper  
“Robust Motion Control with AMIS-3062x Stepper Motor Drivers”,
