Technical Architecture & Functional Positioning

This drive controller operates at the power amplification layer in the DIAX04 modular system, converting regulated DC bus power into precise variable-frequency outputs for a single motor axis. Its single-axis design complements dual-axis HDD modules, allowing optimized configurations where mixed axis requirements exist—reducing costs and space compared to uniform dual-axis setups. The internal blower ensures effective heat dissipation from IGBT power stages, supporting high continuous currents without external cooling aids.

Core technologies encompass pulse-width modulation with high carrier frequencies, closed-loop control supporting resolver or encoder feedback, and integrated diagnostics for overcurrent, overtemperature, and communication faults. These enable rapid response times essential for contouring accuracy in machine tools or synchronized operations in handling systems. The modular plug-in architecture permits addition of command interface cards (e.g., SERCOS or analog), enhancing flexibility for integration with various controllers.

Engineering advantages include reduced wiring through shared supply modules and robust fault isolation, minimizing downtime in critical processes. In regenerative applications, compatibility with HZB brake resistors prevents bus overvoltage during deceleration, protecting the system during high-inertia stops.

Typical Application Scenarios

Controls main spindles in CNC machining centers, delivering precise speed regulation and high torque at low speeds for threading operations.
Drives feed axes in printing machines, ensuring accurate registration and tension control through fast dynamic response.
Applied in packaging equipment for servo-driven conveyors and fillers, benefiting from internal cooling in compact enclosures.
Used in textile machinery for individual motor control in winding or weaving processes, optimizing energy use with vector control.
Serves as replacement in legacy DIAX04 installations for robotics arms, maintaining compatibility with existing motor and feedback cabling.

Quality Standards & Testing Procedures

Drive controllers in motion systems demand rigorous verification to prevent process interruptions from subtle faults like capacitor aging or contact degradation. Our protocol aligns with Bosch Rexroth guidelines and exceeds typical refurbishment standards.

Each unit undergoes layered testing to replicate operational stresses and confirm factory-equivalent performance.

Visual Inspection & Cleaning

Assess power stages, capacitors, and connectors for wear, thermal marks, or contamination. Clean heatsinks and blower to restore airflow, verifying impeller freedom.
