Kollmorgen AKD-B02407-NBA
Overview:
The AKD-B02407-NBA is a compact, high-performance servo drive from the Kollmorgen AKD product family. The model code decodes as: AKD (AKD Series) + B (240 VAC input) + 024 (240 VAC nominal) + 07 (7 A continuous) + N (no line filter) + B (base functionality) + A (standard configuration). This drive is designed for OEM integration into machines requiring precise motion control with a small footprint.

Structural Features:
- Ultra-compact chassis-mount or DIN-rail mount design
- Integrated EtherCAT connector (RJ45)
- Plug-in terminal blocks for power, motor, encoder, and I/O
- Single LED status indicator (multi-color)
- Conformal-coated PCB for humidity resistance
Working Principle:
The AKD-B02407-NBA implements a space-vector modulation (SVM) inverter with field-oriented control (FOC). The drive samples three-phase motor currents at 16 kHz, performs Clarke-Park transformations, and regulates d-q axis currents independently. Velocity and position loops execute at 1 kHz, synchronized to the EtherCAT distributed clock for deterministic motion across multi-axis systems. The STO function uses a dual-channel safety circuit to remove torque-producing current within 5 ms.
Advantages:
- Smallest footprint in the AKD family — ideal for space-constrained OEM designs
- 16 kHz current loop — excellent torque bandwidth for the size class
- No external line filter required (N variant) — reduces BOM cost
- EtherCAT native — plug-and-play with Kollmorgen and third-party EtherCAT masters
- Integrated safety — eliminates need for external safety contactors in many applications
Applicable Industries:
Medical devices, laboratory automation, semiconductor handling, small robotics, 3D printers, textile machinery, food and beverage packaging.
Installation Requirements:
- Mount with at least 30 mm clearance on top and bottom for heat dissipation
- Use shielded twisted-pair cables for encoder (max 25 m for incremental, 50 m for EnDat)
- Connect protective earth (PE) to chassis ground
- For 1-phase input, verify input current does not exceed 16 A at 200 VAC
Usage Precautions:
- Do not block ventilation slots — overheating will trigger thermal shutdown
- Configure brake resistor in drive parameters even if not currently connected (to prevent DC bus overvoltage on deceleration)
- Match feedback device type in drive parameters before first energization
- Maximum ambient temperature: 45°C (derate current 1.5%/°C above 35°C)
