Applicable Industries

Installation Requirements

1. Mandatory vertical DIN rail cabinet mounting orientation; horizontal installation reduces heat dissipation efficiency by 38%
2. Minimum unobstructed airflow clearance: 60 mm vertical space above drive top edge, 40 mm lateral side clearance
3. DIN rail mounting metal backplane connected to facility star protective earth grid via ≥4 mm² shielded copper earth conductor
4. Motor power wiring specification: ≤15 m length use four-core 1.5 mm² fully shielded copper motor cable
5. BiSS absolute encoder feedback wiring: Double twisted-pair shielded 0.25 mm² cable, maximum transmission distance limited to 60 m
6. EtherCAT bus communication wiring: Standard CAT5e shielded Ethernet cable, install 120Ω terminating resistor at both physical bus endpoints
7. Cable separation rule: High-voltage power cables and low-level signal/EtherCAT cables must route inside independent cable ducts; unavoidable cross routing only via strict 90-degree perpendicular crossing

Operation & Maintenance Precautions

1. Cabinet ambient operating temperature range strictly limited to 0°C ~ +40°C; ambient temperature exceeding 40°C requires linear 15% continuous output current derate per 10°C temperature rise
2. Monthly maintenance step: Use clean compressed dry air to blow dust accumulated on chassis aluminum heat dissipation fins
3. Disconnect all mains AC supply and wait minimum 5 minutes for DC bus capacitors full discharge before disassembling any terminal wiring connectors
4. Prohibit connecting servo motors with rated power exceeding 3.2 kW to this drive unit to avoid permanent IGBT power module thermal damage
5. All BiSS feedback and EtherCAT cable shielding layers must implement double-end grounding to eliminate signal noise drift and position jitter
6. Storage environment must maintain non-condensing relative humidity ≤85%; prohibit long-term deployment in environments with conductive metal dust, oil mist or corrosive vapor
7. All firmware upgrade and parameter configuration operations must exclusively execute via official Kollmorgen WorkBench software
