Keywords: Servo Motors, Servo Drives, Servo Drive

ORMEC’s ServoWire Motion & Logic Controller (SMLC) is at the center of a complete machine control solution that can meet all of your motion, I/O and networking needs. This platform puts ORMEC's motion engine together with a high performance PLC capability and world class open standard software which allows you to focus on solving your application instead of integrating control components.

Key Features

  • High Performance Pentium processors
  • Motion and PLC functions in one cost effective package
  • Three Models  3, 8 and 16 axis models
  • IEC 61131-3 all 5 standard languages
  • Modbus/TCP communications
  • QNX RTOS - real time operating system
  • RoHS compliant

SMLC Controllers

The ServoWire Motion & Logic Controller (SMLC) features high performance computing capability combined with a true real-time operating system (RTOS). Using the industry standard family of Intel 32-bit processors running the QNX RTOS provides plenty of cost effective, robust computing power for even the most demanding multi-axis motion and I/O control applications. SMLCs are used in a wide range of industrial and aerospace markets including packaging, converting, labeling, web & material handling, medical, pharmaceutical, as well as general assembly and winding.

Machine I/O

The SMLC provides a multi-tiered, flexible approach to meeting machine I/O requirements. It has the ability to interface high-speed drive based I/O for microsecond position capture and single servo update response to sensor signals. It also provides sub-millisecond programmable limit switch outputs that are tightly coupled to the motion control.

The SMLC reduces system complexity and lowers total installed cost. Servos are daisy-chained and interface to the controller using a standard IEEE-1394b network interface and cabling.

ServoWire Drive Network

ORMEC’s AC brushless servo motors and ServoWire digital servo drives offer tested and guaranteed performance with the SMLC. The result is maximum performance from a tightly integrated, pre-engineered package that simplifies everything from system integration to maintenance.

Fully digital control offers compelling benefits—eliminating manual servo drive setup and providing real-time software access to all parameters. In an SMLC system, the position, velocity and torque loops are all closed by the digital signal processors (DSPs) in the ServoWire Drives based on position commands sent from the SMLC. Velocity observer software eliminates the need for analog tachometers, and potentiometers are eliminated since all gain and compensation parameters are set in software. All loop adjustments are automatically computed when a motor and its load inertia are specified in ServoWire Pro—greatly simplifying servo system tuning.
