Kollmorgen AKD-P02407-NCP
Product Overview:
The AKD-P02407-NCP is a digital servo drive from Kollmorgen’s AKD-P product family. This is Kollmorgen’s flagship servo drive platform, designed for demanding multi-axis motion control applications. The model number decodes as: AKD = AKD servo drive platform, P = P-series (high-performance, Ethernet-enabled), 024 = 24 A continuous current rating, 07 = 7 kW peak power capability, NCP = option code specifying N = No internal braking chopper, C = CANopen communication, P = Position loop filter option (advanced).

Construction & Materials:
- Power Stage: IGBT modules, 650 VDC rated, liquid-cooled heatsink (internal fan optional)
- Control Board: Multi-layer PCB, 32-bit DSP + FPGA architecture
- Enclosure: Die-cast aluminum, EMI-shielded
- Connectors: Removable terminal blocks for power, motor, encoder, I/O
- Cooling: Internal heatsink + fan (optional external liquid cooling for continuous 24 A)
- Brake Chopper: Not included (N option) — external brake resistor required (e.g., 60WKS series)
Functional Features:
- EtherCAT master/slave — deterministic multi-axis synchronization < 1 μs jitter
- CANopen CiA 402 — full servo profile support, 7 operating modes
- Advanced Position Filter (P option) — notch filter, low-pass filter, and observer-based vibration suppression
- Auto-tuning — on-the-fly inertia identification, friction compensation
- Safety Functions — STO (Safe Torque Off), SS1 (Safe Stop 1), SLS (Safely Limited Speed), SLP (Safely Limited Position) — SIL 2 / PLc per IEC 61508
- Regenerative Energy — requires external brake resistor (no internal chopper per N option)

| Efficiency at Rated Load | > 95% |
| Standby Power Consumption | < 15 W |
Advantages:
- 24 A continuous in compact chassis — high power density for machine builders
- No internal brake chopper (N) — reduces cost and heat when external resistor is already specified
- CANopen standard (C) — immediate compatibility with most European motion controllers
- Advanced position filter (P) — built-in vibration suppression eliminates need for external notch filters
- EtherCAT ready — supports high-speed distributed motion architectures
- Full safety function set — SIL 2 without external safety relay
Applicable Industries:
- CNC Machine Tools — 5-axis milling, turning centers, grinding machines
- Semiconductor Equipment — wafer steppers, die bonders, inspection systems
- Printing & Packaging — multi-color register control, high-speed cutting
- Robotics — multi-axis robotic arms, SCARA, delta robots
- Metal Forming — press drive servo retrofits, roll stand control
Installation Requirements:
- Mount vertically or horizontally with minimum 100 mm clearance above and below for airflow
- Power wiring: 3-phase 380–480 VAC, minimum 6 mm² copper cable per phase
- Motor wiring: shielded cable, maximum 15 m (unshielded: 5 m)
- Encoder cable: use Kollmorgen-recommended cable, max 10 m for EnDat, 5 m for incremental 20 MHz
- Brake resistor: must be external (no internal chopper), connect to BR+/BR- terminals
- Ground: protective earth (PE) connection mandatory, < 0.1 Ω to mains earth
Usage Notes:
- No internal brake chopper (N) — external brake resistor mandatory for any application with regenerative energy (all deceleration events). Use 60WKS-CE240/06-PB or higher-rated resistor for 24 A drive
- CANopen (C) — configure CiA 402 profile, PDO mapping required for motion control
- Advanced position filter (P) — enables built-in notch filter (frequency and depth configurable via drive software)
- Do not exceed 780 VDC bus voltage — IGBT breakdown limit
- 24 A continuous requires adequate cooling — at ambient > 40°C, derate current by 1.5% per °C above 40°C
- First-time commissioning requires Kollmorgen Workbench software — parameter setup, auto-tuning, and safety configuration
