Working Principle

Three-phase industrial mains AC input passes integrated EMC filter to suppress grid conducted electromagnetic interference, then full-wave diode rectifier converts AC to stable DC bus voltage supplying three-phase IGBT power inverter stage. Main DSP controller executes space vector modulation (SVM) algorithm to generate high-frequency PWM gate drive signals, converting fixed DC bus voltage to variable frequency three-phase sinusoidal AC excitation current for connected servo motor stator windings. Real-time sine/cosine encoder feedback signals are sampled at 16kHz current loop cycle to close torque, velocity and position triple control loops; PDFF control algorithms dynamically adjust output current magnitude and phase angle to eliminate motor position tracking deviation. PROFIBUS-DP bus receives synchronized multi-axis motion commands from host PLC master controller, executing pre-stored electronic gearing, electronic cam and segmented motion trajectory tasks saved in on-board flash memory. Built-in axial fan continuously exhausts heat generated by power semiconductor switching loss through aluminum fin heat sink; internal fault monitoring circuit continuously samples all critical electrical and thermal operating parameters, triggering hardware interlock power stage shutdown upon threshold violation to prevent permanent hardware damage.

Installation Requirements

  1. Mandatory vertical cabinet mounting orientation only; horizontal installation blocks fan forced airflow path and causes irreversible thermal damage to power modules
  2. Vertical stacking installation minimum clearance: 100 mm unobstructed vertical space above drive top surface, 50 mm clearance below drive bottom edge for fan exhaust airflow
  3. Cabinet ambient operating temperature limited to 0°C ~ +45°C; ambient temperature range 45°C ~ 55°C requires linear 20% continuous output current derate per 10°C temperature rise
  4. Mains three-phase power wiring specification: ≥2.5 mm² fully shielded copper cable with braided shielding layer
  5. Motor power wiring specification: For cable length ≤25 m, use 2.5 mm² four-core shielded motor cable; cable length exceeding 25 m requires matching external output choke accessory
  6. PROFIBUS-DP communication wiring: Standard twisted-pair shielded PROFIBUS bus cable, install 120Ω terminating resistor at both physical endpoints of the bus network
  7. Grounding rule: Cabinet mounting metal plate must connect to factory star earth grid via minimum 10 mm² solid copper protective earth conductor
  8. Cable separation regulation: High-voltage power cables and low-level signal/communication cables must route in physically independent cable ducts; unavoidable cross routing must adopt strict 90-degree perpendicular crossing only

Operation & Maintenance Precautions

  1. Control cabinet must maintain minimum IP54 protection rating to prevent conductive dust and metal particle ingress onto drive internal PCB circuits
  2. Strictly prohibit drive operation with damaged or removed cooling fan unit; fan failure leads to permanent power module thermal burnout within 15 continuous operating minutes
  3. Disconnect all three-phase mains AC supply and wait minimum 10 minutes for DC bus capacitor full discharge before disassembling any terminal wiring connectors
  4. Monthly maintenance task: Remove fan intake filter screen and fully clean accumulated dust with compressed dry air to maintain unobstructed cooling airflow
  5. All encoder and PROFIBUS communication cable shielding layers must implement double-end grounding to eliminate signal noise distortion and position jitter
  6. Regular firmware upgrade and parameter backup operations must exclusively execute via official Kollmorgen WorkBench configuration software; unapproved third-party firmware voids all factory warranty coverage
  7. Prohibit deployment of this drive inside control enclosures containing heavy oil mist, conductive carbon dust or acidic/alkaline corrosive vapor atmospheres
