ZF-D200 Series Bus Servo Drive Systems

A Bus Servo System refers to a servo control system that utilizes a communication bus (such as CAN, EtherCAT, SERCOS, or other industrial fieldbuses) to transmit control signals, feedback data, and configuration parameters between a servo drive, servo motor, and a higher-level controller (e.g., PLC, motion controller, or industrial PC). This architecture enables centralized or distributed control of multiple servo axes, offering advantages such as simplified wiring, improved synchronization, enhanced system flexibility, and easier integration with automation systems

Key Components and Features:

1. Communication Bus:
   • Serves as the backbone for real-time data exchange between the servo drive, motor, and controller.
   • Common bus types include CANopen, EtherCAT, Profinet, SERCOS III, and Powerlink, each offering different performance characteristics (e.g., speed, determinism, and network topology).
2. Servo Drive:
   • Receives motion commands and configuration data from the controller via the bus.
   • Converts electrical power to control the servo motor’s position, velocity, or torque.
   • Provides feedback (e.g., encoder signals) to the controller for closed-loop control.
3. Servo Motor:
   • Executes precise movements based on commands from the servo drive.
   • Integrates feedback devices (e.g., encoders, resolvers) to ensure accurate positioning and speed control.
4. Higher-Level Controller:
   • Sends motion profiles, trajectory planning, and system configuration to the servo drives.
   • Monitors system status, diagnoses faults, and coordinates multi-axis synchronization.

Advantages of Bus Servo Systems:

• Reduced Wiring: Eliminates the need for point-to-point wiring, simplifying installation and maintenance.
• Scalability: Easily expands to control additional axes by adding more servo drives and motors to the bus.
• High Synchronization: Enables precise coordination of multiple axes for applications requiring synchronized motion (e.g., robotics, CNC machines).
• Diagnostics and Monitoring: Centralized access to system data facilitates predictive maintenance and troubleshooting.
• Interoperability: Supports integration with various industrial automation platforms and third-party devices.

Applications:

• Robotics: Multi-axis robotic arms and collaborative robots (cobots).
• CNC Machining: High-precision milling, turning, and grinding machines.
• Material Handling: Conveyors, pick-and-place systems, and automated guided vehicles (AGVs).
• Packaging: Filling, sealing, and labeling machines.
• Textile and Printing: Web tension control, winding, and unwinding systems.
