Technical Architecture & Functional Positioning

This dual-axis drive controller operates at the power conversion layer within the DIAX04 ecosystem, transforming regulated DC bus voltage from HVE or HVR supply units into variable-frequency AC outputs for two independent motor axes. Its architecture integrates two inverter sections on a single module, sharing power electronics while maintaining isolated control loops—reducing overall system footprint and cost compared to separate single-axis units. The built-in SERCOS interface enables fiber-optic ring topology for low-latency, noise-immune command exchange with higher-level controls like CNC or PLC systems.

Core technologies include pulse-width modulated inverters with high switching frequencies, closed-loop vector control for precise torque regulation even at low speeds, and integrated incremental encoder evaluation per axis for position feedback. Diagnostic features monitor overcurrent, overtemperature, and bus undervoltage, triggering safe shutdowns to protect connected motors. These elements resolve engineering challenges in synchronized multi-axis motion, such as phase alignment in gantry systems or torque sharing in dual-motor drives, while minimizing electromagnetic interference through optical communication.

From a systems view, the fixed HD32 configuration incorporates SERCOS command modules and supports additional incremental measurement inputs, allowing direct connection to 1 Vpp sinusoidal encoders without external adapters. Firmware, loaded via separate software modules, permits application-specific parameterization for optimal dynamic response. This design excels in high-cycle applications, delivering acceleration without overshoot and maintaining stability under varying loads.

Typical Application Scenarios

Deployed in CNC machining centers for simultaneous control of spindle and auxiliary axes, ensuring precise synchronization and reduced wiring complexity.
