Actronic consists of two parts - the actuator and the drive and control electronics. The motion controller and the power amplifier are the electronical connection between the actuator and the higher level machine control system; they are therefore a fundamental part for the coordinated move to be executed. The motion controller needs to be matched both with the actuator and the higher level machine controller, which has big effect on the performance and the costs of a motion control solution.
Today's modern digital motor controllers offer sufficient intelligence to take care of the motion specific tasks like motor commutation, path calculation for positioning or even a indexer for the specific achsis (preprogrammed motion profiles, single move tasks, etc.) which unloads these taks from the higher level machine control. This topology is called decentralised control architecture and uses fieldbus systems like CANopen, Profibus, Profinet, EtherCAT etc. to communicate with the higher level machine controllers. There are still some controllers for centralised control architecture, in which all the path calculation, interpolation etc. is performed by the central controller; as communication to the amplifier they use mainly analog +/-10V or digital PWM signals as commands for current (sometimes including commutation information, so called UV) or velocity.
We offer the following versions of motion controllers:
We also offer according accessories for our drives / controllers like main input filters, regen resistors, cables, motor chokes, maines chokes, capacitor modules etc. For the CAN-connection we supply several CAN-interfaces and CAN data loggers, which can also be used in applications which are not related to motion control (medical, diagnostics, data logging in all sorts of vehicles or in automotive production etc.):
