CFG5: SELECTION OF CHOPPER MODE
CFG5
Chopper Setting
GND
spreadCycle operation. (TOFF=3)
VCC_IO
stealthChop operation. (GCONF.en_PWM_mode=1)
CFG6: CONFIGURATION OF HOLD CURRENT REDUCTION
CFG6
Chopper Setting
GND
No hold current reduction. IHOLD=IRUN
VCC_IO
Reduction to 50%. IHOLD=1/2 IRUN
Hint
Be sure to allow the motor to rest for at least 100ms (assuming a minimum of 10MHz f
CLK
) before
starting a motion using stealthChop. This will allow the current regulation to set the initial motor
current.
