Integrated Control Hardware

The ServoWire® Motion and Logic Controller

The SMLC is a cost-effective control platform offering 

rugged, industrial hardware, a proven RTOS and industry 

standard networking, programmed using standard IEC 

61131-3 languages. An SMLC system offers low cost, 

compact, proven and reliable components.

Featuring Pentium-class processors.

Two built-in Ethernet ports, two or three FireWire 

ports* (with or without screw downs), three or four 

serial ports*. 

Compact Flash program storage (eliminates hard 

disk) and 32k battery-backed SRAM data storage.

Reliable, QNX real-time operating system. 

*Model Dependent

CoDeSys Development Software

Using industrystandard IEC 

61131-3, you can 

develop a motion 

and I/O program 

using standard 

tools that 

streamline 

development and 

create application 

solutions that are 

both more effective and easier to support in the field. 

There are no software costs when using the ORMEC 

SMLC in your application. 

FireWire motion networking reduces cost & 

complexity

Control one to 16 servos directly from one controller 

without specialized motion control hardware. 

ServoWire® S2D drives are available in 200V and 

400V series. Fourteen models provide continuous 

output power from 600 watts to 24 kilowatts,

Conveniently interface a variety of Servo Motors

Mix and match servo technologies (DC brushless rotary, linear, 

DC brush-type or voice coil motors) in the same drive hardware. 

Continuous stall torques from 3 to 665 lb-in (0.32-75 N-m).

Standalone touchscreen HMIs utilize Modbus RTU 

(Serial) or Modbus/TCP (Ethernet) communications. Or 

you can utilize Windows-based HMIs such as 

Wonderware InTouch, Rockwell Automation RS View, 

Intellution iFIX, CiTect or GE Cimplicity that communicate 

with the SMLC using an OPC Server.

Select among text-based and graphical languages 

to pick the right one for the job -- Relay Ladder

ServoWire® Motion & Logic Controller

Models 30, 80 & 160

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. By combining 

Pentium processors, IEEE 1394b 

FireWire drive networking and Ethernet 

connectivity, the SMLC is a system that 

can control your entire machine. This 

allows you to focus on your application 

instead of integrating control 

components.

The SMLC, ServoWire Drive Network, 

Modbus/TCP and Ethernet IP provide 

state-of-the-art I/O and motion control 

(for up to 16 axes), all programmed 

using any of the five IEC 61131-3 

standard languages including relay 

ladder logic.

SMLC Family of Controllers

The ServoWire Motion & Logic 

Controller (SMLC) family 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 control 

and machine control applications.

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 submillisecond programmable limit switch 

outputs that are tightly coupled to the 

motion control.

General purpose I/O options are fully 

supported using WAGO 750 Series 

Ethernet I/O as well as optional 

Profibus DP Master support. For both 

options, a wide variety of analog and 

digital I/O modules can be cost 

effectively connected to and controlled 

by the SMLC.

ServoWire Drive Network

ORMEC’s AC brushless servomotors 

and ServoWire digital ServoDrives

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 

ServoDrive setup and providing realtime 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. Position update commands

are 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.
