Applicable Industries

Installation Requirements

1. Vertical mounting orientation strictly required; horizontal installation severely restricts heat sink airflow and mandates significant output current derating
2. Maintain minimum 25mm vertical clearance gap above and below drive unit inside electrical control cabinet
3. Cabinet forced convection cooling fan mandatory if internal cabinet ambient operating temperature exceeds +40°C
4. CANopen bus wiring utilizes shielded twisted pair cable with 120Ω terminating resistor installed exclusively at physical bus endpoints
5. Equipment protective earth ground conductor connected to dedicated chassis ground terminal with minimum 2.5mm² copper cross-sectional area
6. Strict separation routing channels for shielded motor power cables and unshielded CANopen bus / low-voltage signal wiring to mitigate electromagnetic interference

Operation Precautions

• Continuous full-load operation at ambient temperature exceeding +45°C requires 30% reduction of rated output current capacity
• AC mains supply must be fully disconnected prior to connecting or disconnecting motor power and feedback cable assemblies
• STO safety channel wiring must maintain complete galvanic isolation from all 24VDC digital I/O signal circuits
• External regenerative braking resistor power rating must be sized to absorb peak deceleration kinetic energy of machine maximum rated load
• Total CANopen bus cable length across all connected drive nodes cannot exceed 1000 meters maximum
• Transparent front terminal safety cover must remain fully closed during all powered operational states to preserve IP20 enclosure protection rating
