Standard and safety control optimized with Omron’s 1S Series AC Servo System with PLe/SIL3

Omron AC servo system PLe/SIL3

OMRON Asia Pacific launches its new 1S Series AC Servo System with Safety Functionality, to help achieve safer manufacturing environments and higher productivity.

Industries within the digital, food, pharmaceutical, cosmetics, and various operations will benefit from the improvements, with productivity and safety of manufacturing equipment.

Manufacturers are under pressure to quickly set up manufacturing equipment due to short product life cycles. Setting up safe equipment requires a skilled equipment designer and software packages for safety & motion design.

In addition, robots using AC servo systems are increasingly being used to maintain social distancing between workers as a preventive measure against infections including COVID-19.  Workers now need to work harmoniously and safely with machines.

The new AC Servo System with Safety Functionality provides eight safety functions to safely run machines.

All the functions satisfy PLe/SIL3  providing the highest-level safety, protecting the safety of operators, machinery, and products while improving the productivity of production equipment.

For example, in case of an emergency stop, synchronized motors decelerate to a stop, and the stationary state is monitored to avoid breakdown of products and machinery and smoothly restart the production equipment.

Moreover, combining with the 1S Series AC Servo System with Safety Functionality.

Automation Software Sysmac Studio, which provides an integrated development environment

from design to commissioning, makes programming easier.

This software helps improve equipment performance and optimize commissioning tasks. At the production floor where people and machines work together, the machines keep running in the machine work area at safe speed in response to approaching people, ensuring the safety

of operators and boosting production efficiency at the same time.

OMRON introduced a strategic concept called “Innovative-Automation” consisting of three innovations or “i’s” - “integrated” (control evolution), “intelligent”  (development of intelligence by ICT), and also, “interactive”  which is to do with new harmonization between people and machines.  

Key features include: higher productivity and safer environment through advanced motion safety functions allowing machines to keep running. This improves maintenance and changeover efficiency while protecting the safety of operators, products, and machinery.

Also, the highest-class safety is included through the eight motion safety functions, which meet PLe/SIL3 according to ISO 13849-1, IEC 61508, and IEC 62061.

The Automation Software Sysmac Studio enables standard and safety control to be designed and simulated in a sequential manner. Commissioning time of the servo system and safety system can be reduced by approximately 35%.

One Cable Technology is used for the cable to connect the servo drive and servomotor.

Power, encoder, and brake are integrated into one pre-assembled cable.

The rotating connector of the servomotor allows change of the cable outlet direction.

These features facilitate cable connection and disconnection during equipment layout change and maintenance, which increases design flexibility.
