he Drives & Motion Division of Yaskawa America, Inc. launched the SigmaLogic7 Compact, a servo amplifier that makes it possible to add the performance of a Sigma-7 servo system in machines using Rockwell Automation programmable logic controllers.
SigmaLogic7 Compact builds on the legacy of the SigmaLogic, the first Yaskawa SERVOPACK to include “Add On Instructions” (AOIs) for the Rockwell ControlLogix and CompactLogix family of programmable logic controllers. This capability makes it possible to send instructions programmed using RSLogix5000 (v17 and above) directly from a PLC to SigmaLogic7 Compact. No other programming software is needed.
SigmaLogic7 Compact packs all the features of a Sigma-7 amplifier into a smaller package, conserving space in crowded control cabinets.
Features:
- Direct replacement – Sigma-7 products are readily compatible with Sigma-5 servo systems.
- Performance – industry-leading 3.1 kHz bandwidth delivers significantly improved settling time.
- Easy implementation – a package of tuning functions automatically tunes a servo system without user effort, compensating for machine inertia, vibration, ripples, friction, and other artifacts.
- Reliability – tuning accuracy is maintained despite inertia changes up to 30:1; the system automatically compensates for interruptions from electrical interference.
- These innovations combine to offer machine builders and end users a significant improvement in productivity and a boost in Overall Equipment Effectiveness (OEE) with less effort and fewer concerns about compatibility.
