Positioning controllers

The perfect solution for any task.

The EPOS4 product line offers versatile and powerful positioning systems for maxon DC and BLDC motors that are easy to integrate.

maxon EPOS4: A full range of positioning controllers.

EPOS is short for Easy to use POsitioning System. The CiA® 402 positioning controllers from maxon can easily be integrated into an extensive range of master environments, from single axis systems to highly complex multi-axis applications. 

EPOS4 performance features

  • Very high level of power density
  • Convincing control performance even with highly dynamic motors
  • Networkable & IoT ready
  • Extensive feedback options
  • Protective functions for controller and drive
  • Configuration, integration, and communication via a variety of interfaces
  • Easy commissioning with EPOS Studio GUI

Positioning controllers from maxon: Key information at a glance.

Robotic, analysis, and handling systems require compact integration of a large number of energy-efficient drives, combined with highly dynamic controllers and a linked bus system. With EPOS4 Modules from maxon, individual multi-axis systems can be implemented using CANopen or EtherCAT without major development costs.
