AMD5x Multi-Axis Servo System

The EtherCAT®-based AMD5x Series is a multi-axis servo system that delivers high efficiency and performance motion control for rotary and linear motors. The bussed system architecture significantly reduces the complexity of multi-axis control implementation to simplify the installation process. The system simply attaches the required number of drives at various output current ratings to the central Passive Infeed Unit (PIU). The robust AMD5x Passive In-feed Unit generates a shared DC-Link that supplies multiple servo drives and communicates across an EtherCAT® fieldbus. Detailed drive configuration and turning parameters can be customized easily for unique applications designed to optimise system performance.

The AMD5x Series consists of drive models with continuous current ratings of 12A, 20A or 35A, and a 15KW central PIU with direct connection to 380-480VAC 3 phase input. The drive’s large encoder bandwidth and ultra-low current sensing noise enhance its excellent operating characteristics. The build-in high-speed probe inputs, galvanic isolated motor temperature sensor input and brake control simplify the system integration. The PIU provides power to all bussed drives by converting 3 phase mains to a filtered DC supply and also has the ability to diagnose various system faults.

Motion control is performed by the drive controller, which accepts position feedback from motor encoders and/or separate linear scales.  The drive utilizes state-of-the-art current-regulated, pulse-width-modulated voltage-source inverter technology to manage motor performance.  In general, the drive control receives motion control commands via a higher-level controller, which is based on an Ethernet-based field-bus interface. The AMD5x Drive also supports position, velocity and torque control modes, making it the perfect solution for even the most complex application.
