  5. Dedicated dual-channel STO safety wiring terminal block isolated from all low-voltage control circuits to eliminate safety signal interference
  6. Plug-and-play EtherCAT daughter card pre-installed at factory, no field hardware modification required

Working Principle

Single/three-phase AC mains input passes built-in EMC filter, then full-wave diode rectifier to generate stable DC bus voltage supplying IGBT power inverter stage. High-speed DSP motion controller processes EtherCAT real-time motion commands, pulse/direction signals or analog ±10VDC torque/velocity setpoints, simultaneously sampling high-resolution encoder rotor position feedback at 16kHz PWM cycle. Triple closed-loop PI-PDFF control algorithms dynamically adjust three-phase sinusoidal output current to eliminate position tracking deviation. During load deceleration, regenerative motor energy is consumed by internal dynamic braking resistor to stabilize DC bus voltage. Dual STO safety channels cut off all power gate drive signals instantly upon safety trigger input, removing motor torque output without mains power disconnection. Continuous multi-channel fault monitoring circuit samples all electrical and thermal operating parameters, triggering hardware interlock shutdown once threshold violation occurs to protect drive and connected servo motor hardware.

Applicable Industries

Laboratory precision positioning stages, desktop CNC engraving machinery, medical diagnostic automation equipment, miniature packaging labeling lines, semiconductor micro-assembly workcells, small robotic pick-and-place mechanisms, optical inspection motion platforms

Installation Requirements

  1. Mandatory vertical DIN rail cabinet mounting orientation; horizontal installation reduces natural convection heat dissipation efficiency by 38%
  2. Minimum unobstructed airflow clearance: 60 mm vertical space above drive top edge, 40 mm clearance on left/right lateral sides
  3. Mounting metal backplane must connect to facility star protective earth grid via ≥4 mm² shielded copper earth conductor
  4. Motor power wiring specification: For cable length ≤15 m, use four-core 1.5 mm² fully shielded copper motor cable
  5. Encoder feedback wiring: Double twisted-pair shielded 0.25 mm² cable, maximum transmission distance limited to 60 m
  6. EtherCAT bus communication wiring: Standard CAT5e shielded Ethernet cable, install 120Ω terminating resistor at both physical endpoints of bus network
  7. Cable separation rule: High-voltage power cables and low-level signal/communication cables must route inside 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 step: Use clean compressed dry air to blow dust accumulated on chassis aluminum heat dissipation fins to prevent heat blockage
  3. Disconnect all mains AC supply and wait minimum 5 minutes for DC bus capacitors full discharge before disassembling any terminal wiring connectors
  4. Prohibit connecting servo motors with rated power exceeding 2.2 kW to this drive unit, permanent power module overheating damage will occur
  5. All feedback and communication cable shielding layers must implement double-end grounding to eliminate signal noise drift and position jitter
  6. Storage environment must maintain non-condensing relative humidity ≤85%; prohibit long-term storage or deployment in environments with conductive metal dust, oil mist or acidic corrosive vapor
  7. Firmware upgrade and full parameter configuration must exclusively execute via official Kollmorgen WorkBench software; third-party configuration tools void factory warranty coverage
