Working Principle
Ultra-wide range single/three-phase AC mains input passes built-in passive EMC filtering circuit, then full-wave diode rectifier to generate stable DC bus voltage supplying three-phase IGBT power inverter stage. External analog ±10VDC torque/velocity/position reference command signals transmitted from host PLC motion controller are digitized via high-precision internal ADC converter before processing by dedicated motion DSP chip. DSP hardware executes full triple closed-loop regulation algorithms utilizing real-time resolver or serial absolute encoder rotor position feedback signals, continuously adjusting three-phase output current magnitude and phase angle to maintain target motion setpoint values without tracking deviation. Passive cast aluminum fin heat sink dissipates power semiconductor switching loss heat without forced air ventilation cooling hardware; dedicated hardware fault monitoring circuit continuously samples all critical electrical and thermal operating parameters, triggering immediate safe power stage cut-off operation once fault threshold violation is detected to protect drive and paired servo motor hardware.

Applicable Industries
Metal stamping press auxiliary feed axes, continuous textile fiber production machinery, heavy-duty food processing automated conveyor equipment, paper slitting and winding converting machinery, light-duty metal cutting small CNC machine tools
Installation Requirements
- Mandatory vertical cabinet mounting orientation; horizontal flat mounting reduces passive heat dissipation efficiency by 40% and causes gradual power module thermal degradation
- Minimum surrounding cabinet unobstructed airflow clearance: 70 mm vertical clearance above top surface of aluminum heat sink, 50 mm lateral side clearance on left and right chassis walls
- Drive mounting metal base plate must establish secure connection to facility star protective earth grid via minimum 6 mm² solid copper earth conductor
- Physical separation rule for wiring: High-voltage power wiring and low-level signal/feedback wiring maintain minimum 15 cm separation distance; unavoidable cross routing must adopt strict 90-degree perpendicular crossing only
- Resolver/encoder feedback shielded cable maximum allowable transmission distance limited to 80 meters
Operation & Maintenance Precautions
- Cabinet ambient operating temperature range restricted strictly to 0°C ~ +40°C; ambient temperature exceeding 40°C requires linear 10% continuous output current derate per 10°C temperature rise
- Quarterly maintenance task: Use clean compressed dry air to fully remove accumulated dust buildup from aluminum heat sink fin array to maintain unobstructed passive heat dissipation airflow
- Auxiliary 24VDC control logic power supply must maintain tightly regulated output voltage within 18–36VDC tolerance range; voltage deviation outside this band triggers communication signal dropout and position feedback error
- Disconnect all three-phase mains AC supply and wait minimum 8 minutes for DC bus capacitor full discharge before accessing internal drive wiring terminals for maintenance or modification
- Strictly prohibit drive installation inside control enclosures containing heavy oil mist, conductive carbon metal dust or acidic/alkaline corrosive vapor atmospheres
- All firmware modification, motor parameter tuning and motion profile backup operations must exclusively execute via official Kollmorgen DIGIFAS dedicated configuration software; unapproved third-party configuration software voids all factory product warranty coverage
