Kollmorgen S72402-NA
Product Classification: Multi-Axis Servo Drive — AKD2G Series
Product Overview:
The S72402-NA is a 2-axis servo drive from the AKD2G Series, pre-configured for dual-axis motion control in a single chassis. The “NA” suffix indicates No Analog I/O (digital I/O only variant).

Functional Features:
- Synchronized dual-axis control (electronic gearing, camming, fly cutting)
- Coordinated motion via EtherCAT distributed clock
- Built-in PLC with 128 KB program memory
- Full safety suite: SLS, SOS, SS1, SS2, SLP (Safe Limited Position)
- No analog I/O — all I/O is digital (24 VDC)
Applicable Industries:
- Gantry systems (X-Y axes)
- Plotters and cutters
- Dual-spindle machines
- Pick-and-place robots
Installation Requirements:
- Same as AKD2G single-axis drives
- Ensure adequate airflow for 2-axis heat dissipation
- EtherCAT network termination required at last node
Usage Notes:
- “NA” = No Analog — if analog inputs/outputs are required, select “A” variant instead
- Each axis requires separate motor and encoder cabling
