Kollmorgen AKD-P01206-NBP
Model Series: AKD-P Series
Product Overview:
The AKD-P01206-NBP is a high-power servo drive from Kollmorgen’s AKD-P product line. The “P” designation indicates this is a power-stage-only module (no control board included), designed to be paired with an AKD servo control module. It delivers 12 A continuous current and is optimized for larger motors requiring higher torque and power.

- Connector: M23 24-pin (main) + M12 8-pin (encoder)
Working Principle:
The AKD-P01206-NBP is a power amplifier only. An external AKD control module sends PWM gate signals to the IGBT power stage, which then amplifies the DC bus voltage into three-phase sinusoidal currents for the motor. The control module handles all motion algorithms (position/velocity/torque loops), while the P-module handles high-current switching. Feedback from the motor encoder returns to the control module to close the servo loop.
Advantages:
- Scalable architecture — mix and match P-modules with control modules for exact power requirements
- High continuous current (12 A) without derating up to 40°C ambient
- Extensive I/O (8 DI / 4 DO / 2 AI / 2 AO) reduces need for external I/O modules
- Forced-air cooling ensures reliable operation in high-ambient-temperature environments
- EtherCAT-ready for synchronized multi-axis motion systems
Applicable Industries:
- Injection Molding Machines
- Metal Stamping Presses
- Heavy-Duty CNC Machines
- Printing Presses (Large Format)
- Conveyor and Material Handling Systems
Installation Requirements:
- Mount on DIN rail (35 mm) or panel-mount with 4 x M5 screws
- Ensure minimum 100 mm clearance above and below for fan airflow
- Connect DC bus with 16 mm² minimum cable cross-section
- Connect to AKD control module via dedicated backplane or ribbon cable
- Ground chassis to PE with < 0.1 Ω resistance
Usage Notes:
- This unit is a power stage only; it requires an AKD control module to operate
- Do not connect motor directly to P-module without control module — no motion will occur
- Replace internal fan at 20,000 hours or when noise increases
- Do not block air intake or exhaust vents
