Kollmorgen AKD-P04807-NCE
Product Introduction:
The AKD-P04807-NCE is a high-performance servo drive from Kollmorgen’s AKD-P product line. The “P” variant delivers 2× the control loop bandwidth of the AKD-B variant, making it ideal for high-dynamic applications such as high-speed machining, advanced robotics, and precision synchronization. It shares the same 48A current rating but offers superior servo performance.

Key Differences from AKD-B04807:

|---|---|---|
| Control Loop (Pos/Vel) | 2.5 kHz | 5.0 kHz |
| Current Loop | 12.5 kHz | 25 kHz |

Functional Features:
- 5 kHz servo loop — 2× faster response than AKD-B.
- Enhanced motion smoothing — reduced jerk for superior surface finish.
- 64 cam profiles — double the AKD-B capacity.
- Tighter following error — ±0.5 counts at 1 kHz update rate.
- Advanced vibration suppression — built-in notch filters and disturbance observers.
- EtherCAT DC synchronization jitter: ±0.5 µs — best-in-class for multi-axis coordination.
Working Principle:
Identical topology to AKD-B (three-phase PWM servo amplifier with integrated motion controller) but with a faster DSP processor (400 MHz vs. 200 MHz) and higher-speed current sensing (25 kHz vs. 12.5 kHz). The increased loop bandwidth allows the drive to correct position errors twice as fast, resulting in tighter tracking and smoother motion at high speeds.
Structural Features:
- Same form factor as AKD-B — drop-in replacement.
- Enhanced heatsink with larger fin surface area for higher thermal load.
- Higher-capacity internal fan for increased airflow.
- Same terminal layout as AKD-B — fully compatible wiring.
Material Composition:
- Same as AKD-B, with larger heatsink (aluminum extrusion, 6063-T5).
- IGBT modules: Same 600V/75A class, but with improved thermal interface material (TIM).
Advantages:
- 2× bandwidth — essential for high-speed CNC and robotics.
- Tighter synchronization — ±0.5 µs EtherCAT DC jitter.
- Smoother motion — reduced mechanical wear and better surface finish.
- Drop-in compatible with AKD-B — upgrade without redesign.
Applicable Industries:
- High-speed CNC machining (milling, grinding)
- 6-axis and SCARA robotics
- Semiconductor wire bonding
- High-speed pick-and-place
- Print and packaging (high-speed register control)
- Laser cutting and welding
Installation Requirements:
- Identical to AKD-B04807-NCA.
- Ensure adequate cooling — AKD-P generates more heat; maintain minimum 75mm clearance above drive.
- Use shielded motor cable — high bandwidth makes drive more sensitive to EMI.
Usage Precautions:
- Identical to AKD-B, plus:
- Do not use AKD-P with low-resolution encoders (< 17-bit) — bandwidth advantage is wasted.
- Tune carefully — higher bandwidth requires precise tuning; use Kollmorgen Auto-Tune.
- Do not mix AKD-B and AKD-P on the same EtherCAT network without configuring sync properly — jitter mismatch can cause issues.
