A new SERVO AMPLIFIER and SINGLE-AXIS CONTROLLER in a single compact package is the latest product introduced by motion control and robotics specialists YASKAWA.

The SIGMA-7Siec sets new standards for control of single-axis applications and has been developed to enable machine builders and automation end-users to benefit from reduced set-up times and precise, reliable control.

The controller is ideal for applications which require the control of only one servo motor, yet which need an exceptionally fast, precise and reliable servo system performance.

The new Sigma-7Siec builds on the success of YASKAWA’s existing product the MP2600iec which also provides an amplifier/controller combination. The new unit accomplishes both functions while utilising the smaller footprint of an individual amplifier which saves space in restricted control cabinets.

Sigma-7Siec also marks a significant step forward in servo-system performance and benefits from the ongoing development of YASKAWA’s new family of Sigma-7 servo motors and amplifiers.

For example, a bandwidth of 3.1 kHz sets a new standard for servo response and YASKAWA’s advanced set of servo tuning algorithms ensure outstanding vibration suppression, auto-tuning and tuning-less commissioning without the need for installer intervention.

Sigma-7Siec also offers the advantages common to all Sigma-7 SERVOPACK amplifiers, including; Open communication, EtherNet/IP and Modbus/TCP for connectivity to nearly every HMI & PCI on the market.

Also, IEC 61131-3 programming to ensure that programs are developed and executed with predictable behaviour, programmable outputs to reduce panel cost and space requirements when only a few outputs are necessary.

Many third-party remote I/O modules, along with YASKAWA’s own SLIO Vipa I/O, can be interfaced with the Sigma-7Siec system via Ethernet.

Furthermore, a built-in web server function offers standard controller diagnostic information which eliminates the need for special monitoring/maintenance software.
