Multi-axis controllers are units designed to generate the motion trajectories of machine axes that need to be interpolated with each other.
Different types of motion controllers depend on the kind of communication to the HMI (Ethernet or PCI bus) rather than communication to the drives (Ethercat or analog) or whether the drives can be integrated.
AMK’s iSA controller is particularly interesting: designed to be installed directly on the machine, it has an IP65 degree of protection and a mechanical closure to withstand external stresses.
