Compact design

SystemOne CM sets the standard for compactness in automation systems. For a typical configuration of 6 axes including auxiliary voltage supply, SystemOne CM saves approx. 40 % of space in the cabinet compared to conventional multi-axis systems, and another 60 % compared to the use of automation systems with single axes.

SystemOne CM achieves its compactness through the following features:

  • Supply unit with built-in 24 V power supply
  • Three-axis controller
Illustration of integral safety components built into ServoOne CM


Safety technology is an integral part of ServoOne CM. By high level of safety, extensive functionality and response times of 2 ms all applications solvable:

  • Standard
    STO acc. to SIL3, PL e, KAT 4, SBC acc. to SIL2, PL d, KAT 3
  • Option
    Safe motion functions such as SS1, SS2, SOS, SLS, SLI, SDI and SLP acc. to SIL3, PL e, KAT 4
  • Safety PLC
    The safety PLC built into the drive controller can respond to events quickly and with great flexibility.

  • Easy installation
    Installation costs are greatly reduced compared to other conventional drive engineering solutions, firstly because fewer components are needed and secondly because these components can be connected to each other quickly and easily using a simple connection system.

  • One-cable technology
    SystemOne CM supports one-cable technology as well as conventional encoder systems This makes it possible to omit the encoder cable entirely and further simplify installation. The encoder information and the motor temperature are transmitted using just 2 wires of the motor cable.

Dynamic and precision

ServoOne CM has a range of functions whose goal is to increase the dynamic and precision of machines.

  • Computing power
    Powerful drive ASIC with 32-bit micro-controller and floating-point unit for each axis controller, triple-axis controller without loss of computing power.

  • Control functions
    Compensation of encoder errors, errors in the mechanical transmission path, friction and torque-ripple, hiding resonance frequencies, predictive feed-forward control structure with pico-interpolation.

  • Auto-tuning
    Identification of the mechanical systems of the machine and automatic parameter configuration of control structures and parameters.
