Model Definition (Core “W” Meaning)

DDS2.1: DIAX02 drive platform, firmware version 2.x

W: Internal cabinet air cooling (heat dissipated inside the control cabinet via convection/ventilation; compact, no external fan)

###: 2‑digit continuous current rating (e.g., 050=50 A, 100=100 A, 150=150 A, 200=200 A)

‑D/‑DSxx: Feedback/communication options (e.g., D=DSF digital feedback; DS04=SERCOS interface)

Technical Specifications (W‑Series Base)

Electrical

DC bus: 300 V DC ±15% (from TVD/TVM power supplies)

Control supply: 24 V DC (20–28 V DC, ~1.1 A consumption)

Continuous current: 15 / 50 / 100 / 150 / 200 A

Peak current: 2× continuous (short‑term, e.g., 100 A cont. → 200 A peak)

Control loops: Current (125 μs), Speed (500 μs), Position (2 ms)

Compatible motors: MDD/MKD synchronous, LAR/LAF linear, 2AD series

Mechanical & Environmental

Cooling: Internal cabinet airflow (W‑type) (no external blower; relies on cabinet ventilation)

Protection class: IP20 (front), IP10 (overall)

Operating temperature: 0 °C to +45 °C (20% derating @55 °C)

Storage temperature: -30 °C to +85 °C

Max altitude: 1000 m (35% derating above)

Dimensions (W×H×D): 150 mm × 408 mm × 180 mm

Weight: ~7.5 kg (lighter than A‑type external cooling)

Interface and Communication Configuration

Motor feedback: X4 (DSF digital servo feedback standard; optional RSF resolver)

System bus: Shared 300 V DC bus for multi‑axis parallel operation

Communication: Modular slots U1–U5 (SERCOS DS04/DS54, analog, or fieldbus cards)

Digital I/O: 6 isolated inputs / 3 isolated outputs (expandable via modules)

Service port: RS232 (IndraWorks setup/diagnostics)

Core Functions

Three‑loop precision control (current/speed/position)

Compact internal cooling (W‑type) for space‑saving cabinet installation

Modular feedback/communication expansion for flexible system integration

Comprehensive protection: Over/undervoltage, overcurrent, short circuit, overheat, feedback loss

Torque/speed/position control modes

DIAX02 firmware compatible (FW module ordered separately)

Application Scenarios

Medium‑power CNC axes (milling/turning machines)

Multi‑axis textile, printing, and packaging machinery

Assembly lines and material handling robots

Space‑constrained control cabinets (no external blower needed)

DIAX02 system upgrades with internal cooling

W‑Type vs. A‑Type Cooling (Key Difference)

Type Cooling Method Weight Best For

W Internal cabinet air (convection) ~7.5 kg Compact cabinets, medium power (≤150 A)

A External blower (cabinet exhaust) ~11 kg High power (150–200 A), heavy‑duty continuous operation

Usage and Maintenance

Ensure cabinet airflow ≥ 350 m³/h for internal cooling

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/control wiring before power‑on

Configure via IndraWorks (match motor/load parameters)

Clean heatsink/air passages every 6 months; inspect terminals

Calibrate control loops/feedback annually
