Multi-Axis Motion Controller

Multi-Axis Motion Controller operates in conjunction with Elmo Servo Drives

CAN Bus Interface - Ethernet TCP/IP , RS-232, CANopen Communicates

Elmo's Maestro is a network-based, multi-axis motion controller-CAN Bus Interface that operates in conjunction with SimplIQ intelligent servo drives to provide a comprehensive system-based solution.

The Maestro is based on efficient and cost effective distributed motion control architecture to share the motion processing workload. It contains a rich feature set which combines sophisticated motion control, advanced communication and full programming capabilities.

Network-Based Motion Control
Distributed Motion Control Architecture
The Maestro's distributed motion control architecture enables allocation of the workload between the controller and the SimplIQ intelligent servo drives. Within this architectural framework, the Maestro's role is primarily a managerial one with responsibilities that include network management and access, motion control synchronization and trajectory manipulation. The servo drives are responsible for the servo loops (current, velocity, position) with single or dual feedbacks, deployment of local filters, local programming and execution as well as the other functions.
Maestro Advantages
  • Load balancing on the system by distributing the intelligence between the controller and the intelligent drives
  • Flexibility to add up to 48 drives on a single bus with only a simple Maestro re-configuration
  • Reliability by using digital command signals on a real-time deterministic networking
  • Comprehensive diagnostics of the network and individual drives
  • Cost effectiveness by reducing expenses on wiring and space requirements, and offering a simple and dependable solution
  • Reduced cost of ownership by eliminating the need for dedicated motor, drive and controller
Maestro Functionality
