Product Overview:
The AKD-B02407-NBS is a single-phase input servo drive optimized for applications where three-phase power is unavailable. It provides the same advanced motion control and EtherCAT capability as the three-phase AKD variants in a smaller power envelope.

Technical Specifications:

Parameter Value
Input Voltage 200–240V AC Single-Phase
Continuous Current 7A RMS
Peak Current 24A RMS
Continuous Power Rating ~1.5 kW (at 240V)
Peak Power Rating ~5 kW (at 240V, short duration)
Control Modes Position, Velocity, Torque, CSP, CSV, CST
Feedback Interface Sin/Cos Encoder, Hiperface DSL, EnDat 2.2, BiSS-C, Resolver
Communication Protocol EtherCAT, CANopen
Safety Functions STO, SS1, SLS, SLP, SOS — SIL 3 / PL e, Cat. 3
Operating Temperature 0°C to +55°C
Enclosure Rating IP20
Dimensions (Approx.) 140mm × 115mm × 72mm
Weight ~1.2 kg

Functional Features:

  • Single-phase input with active PFC (Power Factor Correction) >0.95
  • NBS configuration includes EtherCAT bridge mode for daisy-chain topology
  • Integrated web server for remote diagnostics via standard browser
  • Kollmorgen Auto-Tune with one-push commissioning

Advantages:

  • Full AKD feature set on single-phase power — no performance compromise vs. three-phase models
  • Eliminates need for external transformer in 240V-only facilities
  • NBS variant supports network daisy-chaining without external switches

Applicable Industries:
Light Industrial Automation, Conveyor Systems, Medical Devices, Food & Beverage Processing, Laboratory Automation, Small CNC Routers

Installation Requirements:

  • Single-phase 240V ±10% supply required
  • Neutral conductor must be connected
  • Minimum 100mm clearance on all sides for natural convection cooling

Usage Notes:

  • Peak current (24A) limited to 3-second bursts; sustained operation above 7A triggers thermal protection
  • NBS configuration requires EtherCAT network planning — confirm slave device count <16 per master
  • Use Kollmorgen-approved motor cables only (part numbers listed in Workbench)
