Waukegan, Ill. The Drives & Motion Division of Yaskawa America, Inc. announces the release of SigmaLogic, a new Sigma-5 servo option that can be connected to Rockwell PLCs with Add-On Instructions (AOIs). SigmaLogic allows users to control Yaskawa Sigma-5 SERVOPACKS from within a Rockwell RSLogix5000 program.

SigmaLogic can be used in 2 ways:

• Use individual motion function block Add-On Instructions (AOIs) in RSLogix5000 PLC programming environment
• Use AOIs to start a pre-defined motion sequence stored in the SigmaLogic axis

The Yaskawa-written and tested AOIs are compatible with all CompactLogix and ControlLogix
PLCs using RSLogix5000 software v17 and above. Right-click instruction help is available for all AOIs in the PLC programming environment. All AOIs are named are named to be familiar to Rockwell users.

SigmaLogic can be used in conjunction with LogicWorks™, a software utility that allows users to create individual move profiles and sequencing for their application. Sequence table and configuration data can be uploaded or downloaded to or from LogicWorks .

Use as many SigmaLogic(s) as you have unused connections in your PLC. Perform basic point to point moves, blended speed moves, homing, jogging and gearing to an external encoder using either direct commands or a 200 point configurable sequence table. Use the extra 8 inputs and 8 outputs on the SigmaLogic servo system in an indexing sequence table or in your PLC application.

Additionally, SigmaLogic contains all of the key features of Sigma-5:

• Tuningless mode automatically adjusts for up to 20:1 in load to rotor inertia mismatch allowing smaller motor and reduced gearing
• Vibration suppression reduces noise during operation improving tracking and settling time resulting in very smooth edges of machined parts
• 20 bit absolute encoders
• 50 watts to 15kW. 100, 230 or 480 VAC input
• UL/CE/RoHS
• Integrated safety (Safe torque off)
