ServoOne product range

Single-axis and multi-axis systems

High-performance servo controllers for sophisticated solutions

The modular design of the ServoOne product family guarantees its optimal integration into your machine process at all times. A fine-tuned single-axis system and an energy-efficient multi-axis system cover all applications in a broad performance spectrum. Whether using high-speed field bus communication with the central multi-axis machine controller or distributed Motion Control intelligence in the drive controller, ServoOne excels at both.

Function packages

The controllers of the ServoOne product range can be ordered with specially customized function packages. They are then equipped with extended software and, if applicable, hardware. The iPLC function package can be combined with other function packages.

Hydraulic function package

The servo hydraulic system (‘servo pump’) combines the advantages of an electric servo system with the power density of a hydraulic drive. The servocontroller of the pump motor provides the closed-loop control of the hydraulic state variables (pressure, flow rate, cylinder position if applicable).

iPLC function package - IEC 61131 programming

The IEC 61131 programmable iPLC shares the ServoOne micro controller platform with the drive controller. This allows optimal access to all system and control parameters as well as interfaces.

HF function package (high frequency)

The HF function package is perfectly suited to spindles and turbo machines. Its main characteristics include the maximum rotating field frequency of 1600 Hz with selectable switching frequencies up to 16 kHz and adapted control structures.

Field bus diversity

This product range provides a flexible integration into control and automation engineering.

ServoOne offers a wide range of different field bus systems.

  • RealtimeEthernet-based communication interfaces such as:
    EtherCAT, Sercos III, PROFINET IRT or PowerLink

  • Sercos II + III as established communication interfaces in the machine tool

  • Tried-and-tested field bus interfaces such as CANopen based on the DS301/DSP402 profiles and PROFIBUS DPV1 round out the ServoOne field bus portfolio.

ServoOne Junior

High-performance servo controller for the lower end of the performance range

Optimized for the lower end of the performance range, the ServoOne Junior servo controller comes with all the technology features of the ServoOne product family. The full functional compatibility and handling of the servo controllers within the ServoOne family is always guaranteed.

ServoOne Junior easily bridges the gap between cost-optimization, minimal size and maximum functionality. The integration of high-speed field bus systems and latest encoder interfaces guarantees future-proof flexibility. Extensive motion control functions provide a wide range of possible solutions.

  • 3 - 8 A rated current at 1/3 x 230 V AC
  • 2 - 16 A rated current at 3 x 400 - 480 V AC
  • Overload capacity up to 300 %

Maximum applicability

Built-in iPlc

Integrated programmable single-axis positioning and sequence control

  • Customer-specific adaptation of the controller to the required motion
  • Quick on-site adjustment if requirements change
  • Programming in IEC 61131-3 languages
  • Programming system CODESYS 3.x
