With this standard application, low-frequency load oscillations can be greatly reduced by modifying the motor setpoint curve. Load oscillations caused by movement commands often have a negative effect on positioning accuracy and dynamics.

ElastiComp modifies the motion profile of the motor based on the mechanical parameters of the system so that the load-side oscillation is compensated by a counter-movement of the motor in the acceleration phases, even without a load encoder. The contour accuracy of the motion profile is maintained on the load side.

ElastiComp, which is compatible with all S7-1500 controllers, can also be used to reduce liquid sloshing during transportation in containers.
