17 dcStep  
dcStep is an automatic commutation mode for the stepper motor. It allows the stepper to run with  
its target velocity as commanded by the ramp generator as long as it can cope with the load. In case  
the motor becomes overloaded, it slows down to a velocity, where the motor can still drive the load.  
This way, the stepper motor never stalls and can drive heavy loads as fast as possible. Its higher  
torque available at lower velocity, plus dynamic torque from its flywheel mass allow compensating  
for mechanical torque peaks. In case the motor becomes completely blocked, the stall flag becomes  
set.

17.2 Designing-In dcStep  
In a classical application, the operation area is limited by the maximum torque required at maximum  
application velocity. A safety margin of up to 50% torque is required, in order to compensate for  
unforeseen load peaks, torque loss due to resonance and aging of mechanical components. dcStep  
allows using up to the full available motor torque. Even higher short time dynamic loads can be  
overcome using motor and application flywheel mass without the danger of a motor stall. With  
dcStep the nominal application load can be extended to a higher torque only limited by the safety  
margin near the holding torque area (which is the highest torque the motor can provide).  
Additionally, maximum application velocity can be increased up to the actually reachable motor  
velocity.
