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
