ZF-D200 Series High - Performance Servo Drive for Precision Control
A high-performance servo drive serves as the cornerstone of
precision control, enabling nanometer-level control over motor
position, speed, and torque through its high precision, rapid
dynamic response, and robust anti-interference capabilities. It
finds widespread applications in high-end fields such as industrial
automation, robotics, and semiconductor manufacturing.
I. Core Performance Characteristics
High Precision and Resolution
- Position/Speed Accuracy: Capable of precisely reaching target
positions or maintaining target speeds within milliseconds or even
microseconds, with errors controlled below the micrometer level and
even reaching nanometer precision in certain scenarios.
- Feedback Resolution: Supports high-precision encoders (e.g.,
absolute encoders, resolvers) or linear scales with resolutions
exceeding one million lines, enabling picometer-level precision
control.
- Control Cycle: Short control cycles for current, speed, and
position loops (e.g., <100μs), ensuring rapid implementation of
commands on the motor.
High Dynamic Response Capability
- Frequency Response Bandwidth: Extremely fast response to step and
sine wave signals, with millisecond-level acceleration/deceleration
capabilities and short settling times for high-speed tracking of
command changes.
- Current Regulation: High current loop bandwidth (e.g., 200kHz PWM
versions) for instantaneous response to torque demand changes,
supporting advanced algorithms such as model-based control and
adaptive control.
High Overload and High Power Density
- Overload Capacity: Capable of providing several times the rated
torque/current for short periods (e.g., seconds) to handle inertia,
rapid starts/stops, or shock loads.
- Power Density: Delivers high power output within a compact volume,
saving space in control cabinets.
Strong Anti-Interference and Vibration Suppression Capabilities
- Anti-Interference: Robust resistance to power grid fluctuations,
load changes, and environmental interference (e.g., electromagnetic
noise) for stable operation.
- Vibration Suppression: Built-in or software-configurable complex
filters (e.g., notch filters, low-pass filters) effectively
suppress mechanical resonances.
Intelligence and Openness
- Adaptive Capability: Adapts to load or environmental changes
through parameter auto-tuning or adaptive algorithms.
- Communication Protocols: Supports high-speed real-time industrial
Ethernet protocols (e.g., EtherCAT, Profinet IRT) for
microsecond-level communication synchronization.
- Interfaces and Compatibility: Supports multiple standard interfaces
(e.g., CANopen, EtherNet/IP) for easy system integration and
upgrades.
