S72402-NANANA-NA-225 belongs to Kollmorgen all-digital AC servo drive S700 platform. S72402 denotes base hardware rating; NANANA stands for factory-customized option code for interfaces; NA indicates neutral terminal equipped on power circuit; suffix 225 is OEM hardware modification code. Rated continuous output: 24A RMS with wide three-phase input of 208～480VAC, it is a mid-range general-purpose single-axis servo drive within S700 medium power lineup.
Adopting mature AKD control core from Kollmorgen, this unit integrates power stage, multi-fieldbus communication, multi-channel discrete I/O and dual-channel STO (Safe Torque Off). It is compatible with synchronous AC servomotors, induction motors, linear motors and resolver-feedback servo motors. Parameter setup, auto-tuning and fault diagnostics are implemented via official AKD WorkBench commissioning software. Designed for standardized matching on mid-to-high-end automation machinery, it balances dynamic performance and system integration cost. Certified to UL, CE and TÜV safety standards with OEM industrial-grade quality control and globally available standard inventory.

Detailed Features
1. Control Functions
Triple-loop full-mode control: Native torque / speed / position control modes; embedded IEC61131 compliant macro programming for electronic cam, electronic gearing and point-to-point motion. Basic multi-axis synchronization can run without upper-level controller.Cogging suppression algorithm: Proprietary built-in routine eliminates cogging ripple at low speed; linear motor steady-speed accuracy ≤±0.01% rated speed.Multi-feedback compatibility: X1 port accepts EnDat / Hiperface / incremental encoder; X2 natively supports resolver, enabling servo retrofit without replacing existing encoders for legacy machines.
2. Interface & I/O Configuration
Digital I/O: Standard 2-channel 24V digital outputs plus configurable digital inputs for home, positive/negative limit and emergency stop signals.Analog channels: Four ±10V analog inputs & two ±10V analog outputs for analog speed command and torque signal acquisition from master controller.Communication ports: RJ45(EtherCAT), 9-pin D-SUB(CANopen/RS232 debug), dual 15-pin D-SUB encoder ports; all pluggable terminals for convenient wiring.
3. Hardware & Environmental Features
Removable cooling fan: Snap-in standalone fan for individual replacement without full drive disassembly to cut maintenance cost.Shared DC-bus: Parallel DC-bus connection among multiple S700 drives for regenerative energy exchange, reducing total external braking resistors and power loss.Data storage: Onboard MMC slot for firmware, parameter set and fault log storage, supporting offline backup and field firmware update.
Core Advantages
Full-range motor compatibility
A single drive directly runs AKM synchronous servo, induction motor, linear direct-drive motor and high-frequency spindle motor without hardware modification. Multi-type motor coverage cuts spare parts inventory expense.
Flexible fieldbus expansion for mainstream industrial controlsStandard onboard EtherCAT & CANopen; optional slot for PROFIBUS‑DP / SERCOS II / DeviceNet add-on cards for seamless connection with Siemens, Beckhoff, Omron and other PLC brands. Pulse + analog dual command ports simplify retrofitting legacy custom machinery.
Standard built-in STO cuts safety upgrade expenseDual-channel hardware-based Safe Torque Off comes factory fitted to meet EU & US machinery safety codes. CE machinery approval achievable without extra safety modules, ideal for export automation equipment.
Fast commissioning to shorten mass-production cycleMMC card enables one-click parameter cloning across identical drives after one unit setup. Combined with one-click cogging suppression and auto PID tuning via WorkBench, new machine setup time is reduced by over 60%.
Robust EMI-resistant industrial hardware designSix built-in hardware protections: overcurrent, overvoltage, undervoltage, overtemperature, encoder open-circuit and short-circuit, plus optimized DC-link filtering. Lower failure rate than peer Japanese servo drives under harsh environments such as dusty textile, damp food processing and oily machine tool workshops to improve overall equipment effectiveness.
Single-cable feedback reduces wiring costNative support for Hiperface DSL & SFD3 single-cable encoders, merging power and feedback into one cable to lower cabinet wiring quantity, potential fault points and harness procurement cost.
