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.:

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 6620.250 – TrioDrive C / MidiDrive C.
