MICROSTEPPING STEPPER MOTOR DRIVE USING PEAK DETECTING …
Drives implemented using the fast decay mode will have, for the same off time or chopping frequency, a higher ripple current than drives implemented using a slow decay mode. This difference in itself is not significant for most stepper motor drives. Issues with the stability of the current control loop … Retrieve Full Source
