AMCS® - Advanced Motion Control Server

AMCS® [pronounced. a-maks] (Advanced Motion Control Server) is an advanced server designated to controlling brush and brushless DC servo motors as well as stepper and microstepping motors actuating any mechanism. It features much more than a typical stand-alone motion controller with network connectivity.

AMCS is a full-featured web server with embedded multi-axis motion controller in a very compact enclosure. It provides tremendous capabilities in network communication, including the Internet, and at the same time functioning independently through its own system software. The server can be accessed either through a HTML graphical interface or client applications. Devices incorporating the AMCS can be controlled and monitored from any place on the globe through the worldwide computer network. The controller is ideal for many automation applications, such as robotic, machine tools, semiconductor, scientific, medical, packaging, textile and industrial.

AMCS works in the Client-Server network architecture with the additional possibility of creating local sub-networks, in case of a bigger number of control devices. In the latter case, the controllers work in a hierarchical Server-Agent configuration. The server, unlike the agent, has the system software with more features and supervises a group of agents. Both, the server and the agent are capable of directly controlling motor drives.

The motion controller harnesses the power of DSP and ASIC chips to implement the motion control algorithms. It incorporates the advanced PID filter with velocity and acceleration feedforward, bias offset and 32-bit position error. The trajectory generator can create S-curve, trapezoidal, velocity contouring or electronic gearing motion profiles. The axes can be programmed independently or synchronously and can operate in open or closed servo loop modes. Motion functions support among others coordinated linear and circular interpolation, point-to-point positioning and contouring, backlash compensation, jogging and homing procedures.

AMCS is supported by the e-NetMotionä and EasyMotionä programs written in Java. The e-NetMotion client application is a graphical interface allowing the server and agents structure management, user account administration and facilitating access to the control devices depending on the user privilege level. Additionally, it provides a secure access to the system, secure transfer of data, programs and commands, and also remote monitoring of the current status of all controllers in the network. The EasyMotion graphical user interface assists in a quick and easy way to set up and tune even complex electro-mechanical systems.

The controller is programmed by commonly used languages. Thanks to that, it does not require an advance level of programming knowledge. Embedded interpreters make possible writing control programs in G-code and HPGL standards, C language and a language used in controllers from the Galil company. They permit programming of advanced motion trajectories realized by various kinematical configurations.

New PC/104 Motion Controller Board for Embedded Systems

Sunnyvale, CA - Cito Systems, Inc. announces a new product line of high performance feature-rich PC/104-bus multi-axis motion controllers, ideal for embedded system applications. These controllers harness the power of the advanced high-speed DSP chip featuring an advanced PID filter and incorporate ASIC and surface mount technologies. The Millennium controllers are available in configurations of 1, 2 or 4 axes for brush or brushless, mixed brush and brushless as well as stepper or microstepper motors.

The DSP unit provides S-curve, trapezoidal, velocity contouring and electronic gearing motion profile modes for various motor outputs. 64 kByte Dual-Port RAM allows very fast data exchange and to capture on-the-fly motion data for analyzing system performance, tuning servo filter gains and diagnostic purposes. Motion trajectory segments can be blended into the continuous motion path. The fast synchronization signal allows multiple boards to perform coordinated motion.

The boards interface to external components via a 100-pin high density connector. It provides +/-10V differential analog or PWM motor outputs and reads single-ended and differential incremental or absolute encoder signals. The connector also supplies opto-isolated dedicated input signals for limit switches, home and fault functions. They can run from +5, +12V, +24V or +48V level supplies. 8 uncommitted discrete output lines can operate at TTL level or up to 50V. These are high current opto-isolated signals capable of sinking or sourcing maximum 350 mA at 50V and can serve as servo amp enable or drive relays, solenoids, lamps or LEDs. The TTL level signals can be expanded to 128 discrete outputs. In addition the board has 8 discrete input lines and 8 analog input channels working in range of 0 to +5V.

The cards are supported by MotionStation™, an Integrated Motion Environment (IME) that includes drivers, software libraries and GUI applications for all Windows and Linux operating systems. It allows development of any motion control application.

The card is supported by C-MotionPlus™ and CyberMotion™ - extensive C-language software libraries and Windows 95/98/NT/2000/XP and Linux drivers which allow development of any motion control application. EasyMotion, a Windows application package with the industry's first ever MotionWizard, assists in a quick and easy way to set up and tune even complex electro-mechanical systems.

The boards can be used in a variety of industries, such as robotic, machine tool, semiconductor, medical, food processing and textile.
