Description

Product Overview

The Yaskawa SMC-2000-4MW is a high-density, multi-axis servo controller engineered for ultra-precision motion control in heavy industrial automation and advanced manufacturing systems. As the flagship model in Yaskawa’s Sigma-7 series, this 4-megawatt powerhouse integrates four independent servo axes within a single ruggedized chassis, enabling synchronized control of gantry systems, rotary tables, and high-inertia loads with nanometer-level positioning accuracy. The Yaskawa SMC-2000-4MW leverages parallel processing architecture to achieve <1μs axis-to-axis synchronization – critical for semiconductor lithography stages, composite material layup machines, and large-scale additive manufacturing. Its liquid-cooled design dissipates 98% of heat loss without external airflow, making it ideal for cleanroom environments. With EtherCAT connectivity and built-in safety PLC functionality (SIL 3/PLe), this controller redefines performance ceilings for high-throughput production systems.

Major Features and Advantages

Parallel Processing Architecture: Quad-core RISC processors with hardware-based motion engines achieve 31.25 μs servo update rates per axis, eliminating phase lag in high-acceleration profiles (≥10G).

Active Vibration Control: Real-time FFT analysis suppresses mechanical resonance up to 2 kHz, enabling precision machining at 0.1 μm surface finishes even with 50-ton payloads.

SMC-2000-4MW

Energy Optimization: Silicon carbide (SiC) power devices reduce switching losses by 70%, while regenerative energy recycling cuts net power consumption by 40% versus conventional drives.

Cyber-Physical Integration: Embedded OPC UA server enables bidirectional data exchange with MES/SCADA systems, including predictive maintenance analytics for ball screw wear and bearing degradation.

Safety Integration: Dual-channel STO (Safe Torque Off) with cross-monitoring meets Category 4 requirements without external safety relays.

Retrofit Flexibility: Auto-tuning wizard adapts to legacy mechanics, compensating for backlash and compliance in aging equipment.
