1S Series AC servo system


Omron Electronics has released its state-of-the-art servo technology, the 1S AC Servo System.

Developed to allow machine developers complete control and management from a single environment, this servo series is available worldwide and complies with global safety standards.

With the increasing demands for high quality production this servo is designed to meet machine requirements, offering optimized setup and installation, enhancing machine design and productivity.

It offers both networked and hardwired safe torque off (STO) built-in to deliver efficient operation. As safety plays a significant factor in many industries, safety design and installation has been simplified through Functional Safety over EtherCat (FSoE).  Machine speed and accuracy is improved through 125 μs system cycle and 23-bit high resolution absolute encoder for accurate position input and retention of position during power loss.

This servo has an advanced tuning function which reduces settling time and in return allows the servo to run smoother. Various ranges are available with ratings ranging from 230 VAC single-phase (100W to 1.5kW) and 400 VAC three-phase (600 W to 3 kW).

Furthermore, the 1S AC Servo System eliminates up to 20% of labour and hardware costs as it doesn’t require external parts such as cables for safety and controller, terminal block for I/O, brake relay and battery.

It features push-in plus terminals to replace the external I/O terminal that contributes to efficient operation by reducing wiring and maintenance work. The compact size of the servo drive reduces the setup time by 50% as the height of the drive is uniform and compact throughout the range, improving air circulation inside the cabinet.
