2. Shared DC bus rack architecture reduces total power rectifier and braking resistor hardware investment for multi-axis systems
3. Unified rack mechanical layout standardizes cabinet design for high-volume OEM machine manufacturing
4. Dual analog/pulse command interface achieves seamless integration with legacy analog CNC controllers
5. Heavy-duty aluminum heat sink and rack forced air cooling system support 24-hour uninterrupted full-load production operation
6. Complete CE, UL, cUL industrial safety certification for global heavy machinery OEM deployment

Applicable Industries & Equipment

Installation Mandatory Requirements

1. Module must be fully inserted and locked into standard BDS3 metal rack frame; loose backplane connection strictly prohibited
2. Rack-mounted forced cooling fan mandatory; airflow direction must pass vertically through module heat sink fins
3. Vertical rack installation only; no horizontal rack placement permitted
4. Operating ambient temperature range: 0°C ~ 38°C; linear output power derate 3.5% per °C above 38°C, absolute temperature limit 50°C
5. Ambient humidity 10%–85% RH, zero condensation allowed inside rack cabinet
6. Installation altitude below 1000m above sea level; derate 2% output power per 100m elevation increase
7. All motor power and feedback cables must adopt double-shielded heavy-duty wiring with full 360° metal shield grounding at both terminals
8. Minimum clearance between adjacent racks ≥120mm for cross-rack heat dissipation

Standard Operation & Maintenance Precautions

1. Original product production permanently discontinued after 2010; no new factory modules, firmware updates or original internal power board spare parts available
2. Cut off entire rack main AC power and wait minimum 15 minutes for shared DC bus capacitors complete discharge before module disassembly or wiring maintenance
3. Monthly inspection of rack cooling fan airflow and heat sink fin dust accumulation; low-pressure dry compressed air cleaning required for blocked fins
4. Backup all axis motor parameters and gain settings to external PC via RS232 port after commissioning to avoid flash memory data loss
5. Avoid rapid repeated rack power cycling; minimum 60-second interval between power-off and power-on operations to protect rectifier and capacitor circuits
6. Quarterly inspection of backplane gold-plated connectors for oxidation; clean oxidized contacts with industrial contact cleaner to eliminate high-resistance power faults
7. If STO safety fault alarm activates, full continuity inspection of all safety interlock wiring and emergency stop switch contacts is required
8. Operating vibration exposure maximum limit ≤0.6g; vibration isolation base mandatory if rack installed near hydraulic presses or forging equipment
