Aiming and Stabilization Software
Tightly integrated, proprietary service software enables commissioning, performance measurements, parameter handling, analysis and maintenance operation via a graphical user interface connected to...
The Electrical Rotary Gear (ERG) line of drives provide a critical component in the traverse and elevation of a turret by accurately transferring the motor's motion, both while aiming at constant low speeds as well as in stabilize mode, controlling highly dynamic movements.
All linear drives are modular where the servo drive and hand crank can be repositioned if there are location and space restraints. Dual redundant brakes and a manual backup drive (for use when power is off) are also included for system security.
