ABTech, Inc. offers a programmable digital servo motor control and brushless DC amplifier in one complete package. This modular design gives the end user flexible motion control from simple command signal input to complicated single axis closed loop operations. Options available such as RS 232, D.R.O.'s and operator interfaces.

Available with velocity or position display. Selectable motor/control tuning parameters. Mix and match any combination of steps, tuning parameters, or position/velocity comands for each of 16 presets.

The digital controller was designed specifically to work with ABTech's ultra-precision air bearing rotary tables, spindles and linear slide family of products.

ABTech, Inc. has complete multi-axis motion controllers avialable for O.E.M.'s and turnkey systems. Consult ABTech for product information on these controls.

Multi-Axis Motion Controller

multi_axis_motion_controller.jpg
Often precision motion systems have specific requirements which are not satisfied by standard off the shelf controllers. ABTech, Inc builds motion controllers one at a time, developing system specifications using application requirements and customer preferences.

These multi-axis controllers are developed to work with ABTech's ultra-precision air bearing rotary and linear stages to provide our customers with the ultimate in precision motion options. From complex single axis moves with demanding motion profiles to multi-axis turn-key machine systems. Available with up to 8 axes of motion, 19" rack mount, stand alone enclosures and open frame for assembly into O.E.M. control cabinets.

ABTech controllers can be provided with pre-programmed event driven/button activated motion with or without a touch screen monitor, or the system can be controlled from a host computer (drivers available for DOS, QNX, Windows and Linux). More than 64 digital I/O points and 8 analog inputs are available for process control. Built in solenoids, indicator lights, relay and solid-state outputs are all available for added control.

Features:

  • Customized displays
  • One through eight axis configurations
  • Modes of motion include jogging, point-to-point positioning, contouring, linear & circular interpolation
  • Electronic gearing and ECAM
  • Servo loop update rates as low as     62.5 microseconds/axis - faster rates available as an option
  • Linear and circular interpolation includes ellipse scaling, slow-down around corners, infinite segment
  • Feed & feed rate override
  • High-speed position capture and position compare for each axis
  • On-board, non-volatile memory for storing application programs, variables & arrays
  • Intuitive, English-like command language with over 200 commands directly executable by controller
  • Multi-tasking for simultaneous execution of up to eight application programs
  • ISA, PC104, PCI, Compact PCI, VME formats or stand-alone with USB or Ethernet and RS232/RS422/RS485
  • ModBus protocol over TCP/IP
  • 64 configurable I/O
  • 8 uncommitted analog inputs with 12-bit ADC standard; upgrade for 16-bit
  • Controls step motors & servo motors on any combination of axes
  • On-board sinusoidal commutation for brushless motors
