Multi-axis servo system

The multi-axis servo systems consists of motion control modules by Promicon Systems and servo power modules by ESR. It is particularly suited for coordinated multi-axis applications, e. g. in handling and assembly systems or pick+place applications.
What is so special about the multi-axis servo system by ESR is: You can use any type of servo motor with it, e. g.:
  • AC servo motors
  • DC servo motors
  • linear motors
  • solenoid motors
  • direct drives
  • torque motors
  • 2- and 3-phase motors
  • 1 to 50 pole pairs

This page provides you with an overview of the multi-axis servo system. Detailed information on a specific module can be found in the data sheet (coming soon).

Motion control modules

Characterisitics of the motion control modules:

  • for coordinated motions of multiple axes
  • with integrated digital position and velocitiy control for highest accuracy
  • integrated in the SYSTEM-90E controller system by Promicon Systems
  • highest flexibility and dynamics due to multi-tasking operation and minimum reaction times
  • suitable for various position feedback systems (resolvers, incremental encoders, etc.)
  • connection to the servo power modules via uniform pLINK interface
  • integral system diagnostics with alarms and log file recording
  • digital parameterization, programming, and monitoring of the system with just one software
  • integration in higher-level controller systems via Profibus, Interbus, OPC, or pNET (RS 232)

Servo power modules

Characteristics of the servo power modules:

  • for flexibly driving various motor types
  • compact design for direct mains connection
  • easy connection to the motion control module with standard RJ45 cable
  • several devices can be mounted directly next to each other (without lateral gap)
  • suitable for servo motors by ESR Pollmeier or other manufacturers
  • for motor powers from 100 W to 10 kW
  • frequent switching off and on without waiting time possible
