Applicable Industries

Installation Requirements

1. Vertical mounting orientation mandatory; horizontal installation restricts heat sink airflow and requires severe current derating
2. Minimum 25mm vertical clearance gap above and below drive unit inside electrical cabinet
3. Cabinet forced air cooling fan mandatory if internal cabinet ambient temperature exceeds +40°C
4. CANopen bus wiring uses shielded twisted pair cable with 120Ω termination resistor fitted at bus physical endpoints only
5. Equipment protective earth ground connected to dedicated chassis ground terminal with minimum 2.5mm² copper conductor
6. Separate routing channels for shielded motor power cables and unshielded CANopen/signal wiring to avoid electromagnetic interference

Operation Precautions

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