Kollmorgen AKD-P01206-NBPN-D000
Product Introduction: Part of the Kollmorgen AKD® series of Ethernet-based digital servo drives. Provides field-oriented control of Kollmorgen AKM™ motors on 240–480 VAC three-phase supply. NBPN = 480 V power stage (00307), internal regeneration resistor (P), PROFINET RT plus secondary RJ45 Ethernet (N), D000 = standard position indexer firmware.

Functional Features: Highest-bandwidth torque loop in AKD class, wizard-based full-frequency autotune, Kollmorgen WorkBench commissioning, TCP/IP service channel, plug-and-play motor recognition, onboard motion indexing (position, velocity, torque modes).
-
Application Scenarios: Single-axis packaging machines, lab automation, semiconductor handling, light CNC axes, any 480 V machine using PROFINET with a 3 A motor such as Kollmorgen AKM42G or small AKM51 windings.
-
Material & Structure: Aluminum heatsink housing, steel mounting rails, PCB with DSP + FPGA, detachable screw-terminal blocks, D-sub feedback connectors, RJ45 bus connector.
-
Working Principle: Rectifies AC supply to DC bus, inverts to 3-phase sinusoidal PWM output; rotor position from feedback closes FOC loop; motion setpoint received via PROFINET CoE or internal indexer.
-
Mounting Requirements: Vertical mount in enclosed panel, ≥50 mm top/bottom clearance, IP20 requires cabinet; PE conductor sized for 480 V 3φ input; separate motor power and feedback cables by ≥100 mm or use grounded separator.
-
Usage Notes: Internal resistor covers light regen only; for vertical-axis high-decel loads verify resistor energy rating. STO must be dual-channel wired through safety relay. Autotune with real load inertia before production. Derating 1.5 %/°C above 40 °C ambient to 50 °C max.
