OrmecSMLC System Overview

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.

indicating system status.

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.
