CUSTOM SERVO DRIVERS

DR-D-48V-8A

The DR-D-48V-8A is an 18-70Vdc dual-axis 8Arms servo controller for military applications.

 

Its sealed enclosure assures:

  • Protection from humidity, dust, and corrosive substances
  • Minimal radiated electromagnetic emissions

 

Some potential uses are:

  • Vehicle handling and steering
  • Communication and radar antenna steering

 

The control algorithms are designed to meet the challenge

of controlling high speed loads with high bandwidth, as

well as highly resonating mechanical plants that use gear motors

or direct drives.

The DR-D-48V-8A derives its firmware from the DFT-Servo module, enjoying the outstanding DFT servo control tuning and identification tools. It's advanced setup and configuration environment

Facilitate speedy, effective, and documented integration and controller tuning, for:

  • Different motors from various manufacturers
  • Different gearing and sensor schemes
  • Different motion plants, with their inertia distributions and structural resonance frequencies
  • DR-D-48V-8A
