Use non-linear compensation to overcome friction at motion start
Used In:
- All applications
Motion system performance often suffers from problems of motor inertia and friction. Elmo enables the use of several non-linear compensation methods to overcome friction at the beginning of a motion, and so consistently improve performance.
The following diagrams show motion system performance before and after applying a friction compensation algorithm:

Design Features
- Compensation is available for both velocity and position.
- Compensation offsets are defined separately for positive and negative motions. Offsets are given in current units (Amperes).
- When using GS table, the velocity command is used as the index to the scheduled velocity table entry gains.
- Easily configured using the Elmo Application Studio (EAS).
