Technical Specifications at a Glance

The following table provides a comprehensive overview of the key technical parameters for the ACOPOSmicro Stepper Module 80SD100XD.C011-01:

In-Depth Technical Exploration

1. Architecture & Integration:

   • Distributed Intelligence: The module mounts directly onto an ACOPOSmicro base unit (e.g., 8AC106.60-1), which provides power, communication (POWERLINK), and the mounting structure. This distributed approach minimizes cabinet wiring and central processing load.

   • Real-Time POWERLINK: Communication with the central controller (a B&R PLC, like an X20 or Automation PC) occurs over POWERLINK, an open standard for Real-Time Ethernet. This ensures deterministic, jitter-free communication of commands (position, velocity, torque profiles) and feedback (actual position, status, errors) at high speeds, synchronized across all axes in the machine.

   • Centralized Engineering: The entire machine control logic, including motion control for this stepper axis, is programmed within B&R's unified Automation Studio development environment using standard PLC languages (IEC 61131-3) and PLCopen Motion Control function blocks. This eliminates the need for separate drive configuration tools.

2. Advanced Stepper Control Capabilities:

   • High Microstepping & Smoothing: The module generates finely interpolated current waveforms, achieving resolutions up to 256 microsteps per full step. This drastically reduces motor vibration and audible noise, enabling smoother motion at low speeds and higher effective resolution for positioning.

   • Closed-Loop Operation (Optional): While steppers are often run open-loop, this module supports connecting a motor-mounted encoder (differential HTL/RS422). This enables true closed-loop control:

     • Position Verification: Confirms the motor shaft actually reached the commanded position.

     • Stall Detection & Prevention: Detects missed steps due to overload and can react (e.g., stop, fault, retry).

     • Enhanced Accuracy & Torque: Allows for dynamic current adjustment to maintain position under load, improving holding torque and positional accuracy.

   • Sophisticated Motion Profiles: Supports complex motion control modes like Profile Position/Velocity, electronic gearing/camming, and Cyclic Synchronous modes tightly synchronized with other axes (servo or stepper) on the same POWERLINK network.

3. Performance & Dynamics:

   • High Current Capability: Delivering up to 5A peak current per phase allows driving larger, more powerful stepper motors or achieving higher torque/speed performance from smaller motors.

   • Optimized Torque Delivery: Advanced control algorithms ensure optimal torque production across the motor's speed range, maximizing acceleration and usable speed.

   • Fast Response: The tight integration with the real-time controller and high-speed POWERLINK network ensures minimal latency between command generation and execution at the motor.

4. Safety & Diagnostics:

   • Integrated Safe Torque Off (STO): A critical safety feature. The STO input safely disables the power stage, preventing the motor from generating torque. This meets high safety integrity levels (SIL 3 / PL e) for applications requiring safe stopping.

   • Comprehensive Diagnostics: The module provides extensive status and diagnostic information accessible via Automation Studio or the PLC program. This includes:

     • Detailed error messages (overcurrent, overtemperature, short circuit, communication loss, position error, STO state)

     • Real-time monitoring (output current, supply voltage, module temperature, actual position/velocity, DI/DO states)

     • Trace functionality for detailed motion analysis

   • Robust Protection: Features like overcurrent protection, overtemperature shutdown (module and motor temperature monitoring via optional sensor), and undervoltage detection safeguard both the module and the connected motor.

5. Software & Configuration:

   • Automation Studio Integration: Configuration is entirely within Automation Studio. The module is represented as a standard axis object.

   • PLCopen Motion Control: Program motion sequences using standardized PLCopen function blocks (MC_Power, MC_MoveAbsolute, MC_MoveVelocity, MC_Home, etc.), ensuring code portability and readability.

   • Parameterization: Motor-specific parameters (current limits, microstepping settings, thermal constants, encoder parameters) are easily set via intuitive dialogs or wizards. Commissioning tools simplify setup and tuning.

   • Data Access: All parameters and process data are accessible programmatically via the PLC, enabling dynamic control and advanced machine logic based on drive status.

Why Choose the ACOPOSmicro 80SD100XD.C011-01?

• Unmatched Integration: Seamless fusion into the B&R automation ecosystem (single engineering tool, real-time communication, synchronized multi-axis control) drastically reduces engineering effort and complexity compared to standalone stepper drives.

• Elevated Stepper Performance: Delivers smoother operation, higher precision, better dynamics, and closed-loop reliability far exceeding conventional stepper drives.

• Compactness & Density: The modular ACOPOSmicro design allows packing multiple axes (servo, stepper, I/O) into a very small cabinet footprint.

• Future-Proof Technology: Based on open standards (POWERLINK, PLCopen) and integrated into a scalable architecture, protecting your investment.

• Advanced Diagnostics & Safety: Comprehensive monitoring and integrated STO enhance machine uptime, safety, and maintenance efficiency.

• Reduced Total Cost of Ownership (TCO): While the per-module cost might be higher than a basic drive, the savings in engineering time, cabinet space, wiring, commissioning, troubleshooting, and potential downtime often result in a significantly lower TCO.
