Material Composition:

• Housing: Die-cast aluminum with powder-coat finish (lighter than AKD1)
• Power Stage: IGBT modules (650V, higher voltage rating than AKD1 for better margin)
• PCB: 4-layer FR-4, conformal coated
• Connectors: Push-in terminal blocks (faster wiring than screw terminals)
• Heat Sink: Integrated into housing (no external heat sink needed at 750W)

Structural Features:

• Ultra-compact DIN rail mount (35mm DIN rail compatible)
• Push-in terminals for all connections — no screwdriver required
• EtherCAT: 1× RJ45 (daisy-chain)
• USB port for commissioning (no PC software required for basic setup)
• LED status ring (multicolor — green/red/blue)
• Optional: IP54 front cover with transparent window for status LEDs

Working Principle:
Same FOC cascade control as AKD1, but the AKD2G uses a newer generation DSP (faster, more memory) enabling higher loop bandwidths in a smaller package. The integrated safety functions use a hardware safety monitor (independent of the main DSP) for SIL 3 / PL e compliance. The push-in terminal design reduces wiring time by 50% vs. AKD1. EtherCAT distributed clock enables <100 μs cycle times for multi-axis synchronization.

Key Advantages:

• 50% smaller than AKD1 — saves cabinet space
• Integrated SIL 3 / PL e safety — no external safety relay needed
• Push-in terminals — faster installation, no tools
• USB commissioning — configure without PC software
• Higher bandwidth — 2.5 kHz current loop (vs. 1.5 kHz in AKD1)
• EnDat 2.2 / BiSS-C — modern absolute encoder protocol, higher noise immunity

Applicable Industries:

• OEM machine builders (space-constrained cabinets)
• Robotics (compact multi-axis systems)
• Packaging machines
• Medical devices
• Semiconductor equipment
• Any application requiring integrated functional safety in a small package

Installation Requirements:

• 35mm DIN rail mount — ensure rail is rated for 1.5 kg per drive
• 200–480 VAC 3-phase input — use line reactor for 480V systems
• EtherCAT: daisy-chain topology, 120 Ω termination at both ends
• Ground: < 0.1 Ω to cabinet ground bar
• Ventilation: 30 mm clearance on top and bottom (passive cooling — no fan needed at 750W)

Usage Notes:

• Use Kollmorgen WorkBench 2 (new software for AKD2G) or USB web interface for commissioning
• EnDat 2.2 encoder: requires EnDat 2.2-compatible motor (AKM2G or S7200 with EnDat option)
• BiSS-C encoder: requires BiSS-C motor encoder
• Safety wiring: use safety-rated cable (orange jacket per IEC 60204-1)
• Firmware updates via USB or EtherCAT (no separate programmer needed)
