Detailed content

Model Code Breakdown:

  • AKD = AKD2G Platform
  • B = Braking Resistor Included (or Brake Option Installed)
  • 003 = 3 A Continuous Current Rating
  • 06 = 6 (additional variant code — typically indicates feedback/config)
  • N = No Feedback Option (incremental)
  • B = Braking Resistor Installed
  • A = Standard Configuration

Rated Continuous Output Current: 3 A RMS

Peak Output Current: 6 A (30 seconds)

DC Bus Voltage: 48 VDC (auto-sensing 24–48 VDC)

AC Input Voltage: 200–240 VAC single-phase

Input Power Rating: 1.2 kVA

Braking Resistor: Internal, 47 Ω, 100 W (typical)

Communication Interfaces:

  • EtherCAT (primary)
  • EtherNet/IP
  • PROFINET
  • CANopen
  • Modbus TCP
  • Pulse & Direction
  • Analog ±10V

Control Modes: Position, Velocity, Torque, CSP, CSV, CST

Loop Update Rate: 62.5 µs (16 kHz)

Feedback Supported: Incremental (A/B/Z), Resolver (with option)

Safety: STO (standard)

Environmental Rating: IP20

Operating Temperature: 0°C to +50°C

Dimensions (W × H × D): 115 mm × 140 mm × 110 mm

Weight: 0.95 kg (includes brake resistor)

Cooling: Natural convection with internal brake resistor thermally coupled to heatsink

Structural Features:

  • Aluminum heatsink with integrated brake resistor mounting
  • IGBT 2-quadrant power stage with brake chopper circuit
  • M23 connectors: power, motor, feedback

Key Advantages:

  • Internal brake resistor simplifies wiring for vertical-axis applications
  • 3 A rating suits small-to-medium servo motors (AKM11, AKM22)
  • EtherCAT primary enables seamless integration with Kollmorgen and third-party EtherCAT masters

Applicable Industries:

  • Vertical axis on gantry systems
  • Small robot arms (4–6 axis)
  • Linear actuator drives
  • Lab automation stages

Installation Requirements:

  • Mount with 50 mm clearance above for heat dissipation
  • Connect brake resistor terminals internally (pre-wired)
  • Use 2.5 mm² copper for power, 1.5 mm² for motor phases

Usage Notes:

  • The internal brake resistor is rated for intermittent duty — continuous regen will overheat
  • For high-duty-cycle deceleration, add external brake resistor via option card
  • Maximum motor phase inductance: 15 mH
