Motion Controller MC2

The drive system MC2 – including motion controller MC2 and drive amplifiers of the series SD2S – is the solution for machine manufacturers who develop a PC-based application software and look for a well-proven system for the motion tasks. The communication between the motion controller MC2 and the client‘s PC is established via Ethernet based on the DNC-361 protocol.

Using the provided documentation the client can easily implement the protocol into his application software. Then, the various motion functions of the drive system MC2 are available in the application software.

The Motion Controller for Your Machine

MC2 runs a real-time operating system that permits synchronous data transmission to the drive amplifiers. This makes controlled spatial movement of the axes possible. The used optical fiber connection ensures an extremely fail-safe data line. As an option, MC2 also offers an EtherCAT master interface which enables direct data exchange between the MC2 and the application unit, e.g. an exposure unit. 

The drive amplifiers SD2S can evaluate all common measuring systems and reach an exceptional positioning accuracy with very constant speed of the X/Y main axes. In addition, SD2B plus is available for Z-axis positioning, e.g. for focus adjustment of exposure units.  These features ensure a high quality of the manufactured products. As an option, SD2S provides the opportunity to output trigger signals for the synchronization of the application unit, e.g. print head.

This function also allows scaling the motion axes to the resolution of the application unit. MC2 provides up to eight inputs or outputs for your machine.

With an optional, external I/O module the inputs and outputs can be expanded to a maximum of 96 inputs and 96 outputs. The transmission protocol IO-Link 3 ensures reliable data transmission to the I/O system 50.06 via optical fiber cables.

Software for initial operation and parameterization: drivemaster2/drivemaster3

drivemaster2/drivemaster3 is a powerful tool for easy and goal-oriented parameterization and optimization of drive axes. The parameters are used to adapt the drive axes to the mechanical and electrical characteristics of the machine.

OSCAR is an auxiliary program for optimizing machine movements. By means of the graphic visualization speeds, accelerations, and moving characteristics can be set individually for each axis. With this online optimization the machine manufacturer can determine the best possible values for a machine and thus achieve considerable improvements in the machine´s productivity.
