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.

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 :

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”,
