Compact design

KeDrive D3 sets the standard for compactness in automation systems. For a typical configuration of 6 axes incl. auxiliary power supply, KeDrive D3 saves approx. 40% space in the control cabinet compared to commercially available multi-axis systems and 75% compared to the use of automation technology based on single axes.

KeDrive D3 achieves its compactness through the following features:

  • Supply unit with built-in 24 V power supply
  • Three-axis controller

Safety technology is an integral part of KeDrive D3. 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, first because fewer components are needed and second because these components can be connected to each other quickly and easily using a simple connection system.

  • One-cable technology
    KeDrive D3 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

KeDrive D3 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.

Focus on energy efficiency

The majority of energy consumption in factory automation is attributable to drive technology. Here, KeDrive D3 makes an important contribution to cost reduction.

  • Active power regeneration limits peak load consumption and thus connection costs
  • Efficient capacity modules as a dynamic energy storage system
  • Intelligent energy storage systems to protect against grid interruptions increase availability

Automation from a single source

Expand the KeDrive D3 drive system with scalable controllers in the same form factor. Power is supplied directly from the drive system.

The KeDrive D3 controller combines PLC, motion, robotics and CNC applications. With just one platform and just one partner, you can automate even complex systems simply, safely and efficiently.
