DR-D-48V-8A

DR-D-48V-8A

The DR-D-48V-8A is an 18-70Vdc dual-axis 8Arms servo controller for
extreme harsh environments applications.
The control algorithms are designed to meet the challenges of controlling
high speed loads with high bandwidth, as well as highly resonating
mechanical plants that use gear motors or direct drives.

All drives and power systems include and are managed by GFTuner software tools.
Implementation of GFT-Servo allows advanced and complex control schemes, including ‘Gain Scheduling’ for instant handling of changing system dynamics, and Automatic Transfer Function identification, including uncertainty.
The SW tool includes also built in integration and debugging functions.
