Whereever dynamical acceleration, quick traversing, or a high stalled torque are important as well as a high precision of speed and positioning, the SK 1000 E is the best choice. With a mini PLC inside and a field bus connection port, it will ensure control of even the most critical driving jobs.
Rated current: 2 - 20 A, 3 AC 380 V - 460 V
Fully digitized NORDAC SK 1000 E servo controllers with field bus connection are designed to control the torque, speed and position of synchronous motors.
Owning to the flux-current type of control with a sampling time of only 50 µs, this system is extremly dynamic and provides full motor torque even at zero speed. With the rotor position being fed back, a very high speed and position accuracy is obtained which is not load-dependent at all. Even the most sophisticated drive problems can be solved if this servo controller is used. Implemented technological functions such as electronic reduction with any gear ratio desired are among the standard equipment provided.
Other controller functions can be added integrating a integrated PLC unit. The controllers are started up by means of an operating software run by Windows 95, 98, 2000, NT and XP. As a motor/controller database, an oscilloscopic function and numerous test functions are delivered with each new device, starting-up is really easy, with no expert knowledge being required.
