Without electronics and firmware modern motion control just would not exist. Behind any servo or stepper motor we use there is an amplifier and positioning controller. We differentiate between central and decentral (intelligence at each axis, connected with a communications bus system) topology.
In the central control topology all the intelligence is centralised into one dedicated processor (the brain), which is responsible for all tasks regarding axis coordination (including interpolation), path calculation and generation and the position control. Depending on the exact configuration the controller may also be able to do the speed and current control; the command usually is an analog +/-10V signal or a digital PWM or pulse/direction signal.
Some controllers are able to take over responsibility for the motor commutation also, which has the advantage that the feedback needs to be connected to the controller only. The command is provided by two analog +/-10V signals (UV commutation commands) or by two digital PWM signals (digital UV commutation commands). Some controllers can even provide the switching commands for the power ICs directly, so that the power electronics only consists of the semiconductors and some protective circuit.

In the decentralised topology the motion control intelligence is provided by the single axis controllers, to take away the motion control specific tasks from the central processor; the amplifiers in this case are responsible for the motion tasks like path planning etc. For the communication several bus systems like CANopen, Profibus, EtherCAT etc. are available.
The most digital amplifiers today have already quite some intelligence on board (e.g. to provide a very comfortable setup tool) so that they also provide a fieldbus connection in addition to the classical +/-10V interface and therefore they are ideally suited for decentralised motion control architecture.
Since every application has its own specific requirements we supply a variety of amplifiers and controllers to be able to offer the best solution for your application. Please click on any of the menu items on the right-hand side for detailed information on your area of interest.
Changes at MACCON
To whom it may concern:
For various reasons, we have decided to merge the MACCON group of companies into one company. As of 01.09.2021 (current planning) the new company
MACCON GmbH & Co. KG
will be available to you as a your new business partner, with all rights and obligations of the previous companies. This change has no influence on our existing business relationship. All previous agreements will of course remain valid.
Unfortunately, this change requires some formalities that can only be processed sequentially. The local court (business register court) will formally publish various conversion steps. We ask you to wait until this conversion process is completed. We will inform you promptly about the completion of the conversion and provide you with all relevant company data.
We look forward to a continued mutually beneficial business relationship.
We thank you in advance for your patience.
