It can be used for stall detection as well as other uses at loads below those which stall the motor. The stallGuard2 measurement value changes linearly over a wide range of load, velocity, and current settings. Load stallGuard2 Nm Initial stallGuard2 (SG) value: 100% Max. load stallGuard2 (SG) value: 0 Maximum load reached. Motor close to stall. Motor stalls coolStep coolStep is an automatic current scaling based on the load measurement via stallGuard2 adapting the required current to the load. Energy consumption can be reduced by as much as 75%. coolStep allows substantial energy savings, especially for motors which see varying loads or operate at a high duty cycle. Even a constant-load application allows significant energy savings because coolStep automatically enables torque reserve when required. 0,9 Efficiency with coolStep 0,8 Efficiency with 50% torque reserve 0,7 0,6 0,5 Efficiency 0,4 0,3 0,2 0,1 0 0 50 100 150 200 250 300 350 Velocity RPM d cSt e p dcStep is an automatic commutation mode for the stepper motor. It allows the stepper to run with its nominal velocity taken from 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. torque microstep dcStep operation - no step loss can occur operation additional flywheel mass torque reserve M MAX M NOM2 dcStep extended application area M NOM1 Classic operation area with safety margin 0 velocity RPM M : Nominal torque required by application NOM M : Motor pull-out torque at v=0 MAX Safety margin: Classical application operation area is limited by a certain percentage of motor pull-out torque www.trinamic.com
