Working Principle

Single/three-phase AC mains input passes built-in passive EMC filter then full-wave diode rectifier to generate stable DC bus voltage supplying three-phase IGBT power inverter stage. High-speed DSP motion controller processes real-time EtherCAT CoE synchronized motion commands, sampling SFD single-cable integrated rotor position feedback signals at 16kHz PWM cycle. High-bandwidth triple closed-loop PI-PDFF control algorithms dynamically adjust three-phase sinusoidal output current to eliminate motor position tracking deviation and velocity fluctuation. During load deceleration regenerative energy generated by servo motor is consumed by internal dynamic braking resistor to stabilize DC bus voltage fluctuation. Continuous multi-channel hardware fault monitoring circuit samples all critical electrical and thermal operating parameters, triggering instant power stage hardware interlock shutdown upon fault threshold violation to protect drive and matched servo motor hardware.

  3. Native EtherCAT CoE real-time bus supports multi-axis synchronized electronic gearing and electronic cam motion trajectories with synchronization jitter <100 ns
  4. Dedicated SFD single-cable feedback interface reduces total wiring quantity between drive and servo motor by 50% compared to separate power and feedback cables
  5. Integrated internal dynamic braking resistor eliminates external brake resistor accessory requirement for low/medium inertia mechanical loads
  6. Built-in adaptive digital anti-resonance filter suppresses mechanical axis low-frequency oscillation and audible vibration noise
  7. RS232 multi-drop diagnostic port supports batch parameter backup, restore and firmware upgrade via official Kollmorgen WorkBench configuration software

Applicable Industries

Mid-speed automated electronic component assembly equipment, desktop CNC engraving and cutting machinery, optical inspection precision positioning stages, light-duty packaging labeling and dispensing automation lines, laboratory precision fluid handling robotic axes, small robotic pick-and-place mechanisms

Installation Requirements

  1. Mandatory vertical DIN rail cabinet mounting orientation only; horizontal flat mounting reduces passive heat dissipation efficiency by 38% and leads to power module thermal degradation
  2. Minimum unobstructed airflow clearance: 60 mm vertical space above drive top edge, 40 mm clearance on left and right lateral chassis sides
  3. DIN rail mounting metal backplate must connect to facility star protective earth grid via minimum 4 mm² shielded copper protective earth conductor
  4. Motor power wiring specification: For cable length ≤15 m, use four-core 1.5 mm² fully shielded copper SFD single cable
  5. SFD single-cable maximum transmission distance limited to 60 meters
  6. EtherCAT bus communication wiring: Standard CAT5e shielded Ethernet cable, install 120Ω terminating resistor at both physical endpoints of bus network
  7. Cable separation regulation: High-voltage mains power cables and low-level signal/EtherCAT communication cables must route inside physically independent cable ducts; unavoidable cross routing must adopt strict 90-degree perpendicular crossing only

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 task: Use clean compressed dry air to fully remove dust accumulated on chassis aluminum heat dissipation fin array to maintain unobstructed passive heat dissipation airflow
  3. Disconnect all mains AC supply and wait minimum 5 minutes for DC bus capacitor full discharge before disassembling any terminal wiring connectors
  4. Prohibit connecting servo motors with rated power exceeding 3.0 kW to this drive unit; permanent IGBT power module thermal burnout damage will occur
  5. All SFD single-cable and EtherCAT communication cable shielding layers must implement double-end grounding to eliminate signal noise distortion and position jitter
  6. Storage environment must maintain non-condensing relative humidity ≤85%; prohibit deployment within control enclosures containing heavy oil mist, conductive metal dust or acidic/alkaline corrosive vapor atmospheres
  7. All firmware upgrade and motor parameter tuning operations must exclusively execute via official Kollmorgen WorkBench configuration software; unapproved third-party configuration tools void factory product warranty coverage
