Core Function Features, Material Composition, Structural Characteristics, Working Principle, Application Scenarios, Installation & Maintenance Rules

1. Three-Phase High-Voltage Heavy-Load Input Design: Optimized for factory three-phase high-power mains power supply, eliminates the need for step-down isolation transformers in heavy-load high-torque motor application scenarios, reducing overall automation cabinet volume and auxiliary power equipment procurement costs. Built-in three-phase input phase loss detection circuit automatically triggers fault alarm and disables power output if any single input phase wire disconnects or breaks.
2. NANANA Full Incremental Cost-Optimized Variant Exclusive Hardware Design: All absolute encoder related hardware circuits, position backup battery sockets and multi-turn memory chips are completely removed from the drive control board. This variant significantly cuts down component procurement and manufacturing costs for heavy machinery equipment that executes automatic homing cycles after each power startup, with no functional requirement to retain mechanical origin position through power outages.
3. Dual-CPU Independent Separate Processing Architecture: One dedicated high-speed microprocessor exclusively executes all triple closed-loop motion control calculations to guarantee consistent high 1200Hz velocity loop bandwidth without being occupied by bus communication data processing tasks. A second fully independent communication CPU handles all fieldbus data transceiver, onboard digital I/O signal scanning and fault data logging tasks, ensuring zero-delay motion command transmission even under full bus high data load operating conditions.
4. Heavy-Load Optimized Reinforced Power Stage Layout: Reinforced high-current IGBT power modules, thickened internal copper power bus bars and enlarged passive aluminum heat sink fins integrated on the drive housing to support sustained high continuous current output for heavy inertial loads such as large gantry machining axes, vertical heavy lifting platforms and high-torque metal forming forging equipment.
5. Expanded Onboard Isolated Digital I/O Channels: 12 input and 6 output isolated digital I/O ports reserve abundant signal access capacity for heavy equipment multiple limit switches, safety interlock sensors, hydraulic valve feedback signals and auxiliary equipment state detection, eliminating the need to purchase additional external I/O expansion modules for most heavy machinery control schemes.
