Product Overview

The Kollmorgen S72402-NANANA is a high-response servo drive from the AKD Series,engineered for demanding industrial automation applications requiring high dynamics,precision,and reliability.Designed to power Kollmorgen’s AKM(frameless or housed),KBM(direct-drive torque),and TBM(torque motor)servo motors,this drive delivers 7 A continuous/15 A peak current at 3-phase 200–480 VAC,making it suitable for mid-to-high inertia loads in robotics,CNC,printing,and semiconductor handling systems.

The model code S72402-NANANA decodes as follows:

S7:AKD Series,Size 7(frame size)

2:200–480 VAC input

402:Firmware/software variant(often indicates standard feature set)

NANANA:All optional communication and feedback interfaces are not selected(i.e.,base configuration)

Despite the“NANANA”suffix suggesting minimal options,the S72402 still includes EtherCAT as standard(per AKD Series design),along with STO(Safe Torque Off),analog±10 V,pulse/direction,and resolver/EnDat/Hiperface feedback support—making it highly versatile out of the box.

Key strengths include real-time auto-tuning,notch filters,vibration suppression,and dual-loop control(when using external encoders),all configurable via Kollmorgen WorkBench—a free,intuitive PC-based commissioning tool.The drive also supports regenerative energy management,either through a built-in shunt resistor or connection to a common DC bus for multi-axis systems.

Main Features and Advantages

Plug-and-Play EtherCAT Integration:Fully compliant with CiA 402 device profile,enabling seamless use in Beckhoff,Siemens,B&R,and other EtherCAT master systems.

Advanced Motion Tuning:WorkBench software provides FFT-based vibration analysis,auto-gain tuning,and mechanical resonance compensation—reducing setup time by up to 70%.

Motor Agnostic(Within Kollmorgen):Supports a wide range of Kollmorgen motors without hardware changes—just select motor type in software.

Energy Efficient:Regenerative capability reduces heat and energy costs in vertical or high-cycling applications.

Robust Diagnostics:Real-time monitoring of torque,speed,position error,temperature,and bus voltage via web server or WorkBench.

Application Field

The S72402-NANANA excels in:

Industrial Robotics:Articulated arms,SCARA,delta robots

Semiconductor Handling:Wafer transfer,aligners,inspection stages

Packaging Machinery:Form-fill-seal,cartoning,labeling with high-speed registration

Printing&Converting:Web tension control,register correction

Machine Tools:Tool changers,rotary tables,feed axes

It is particularly valued where sub-millisecond response,low jitter,and smooth low-speed operation are critical.

Installation and Maintenance

Installation Best Practices:

Use shielded motor and encoder cables;ground shields at drive end only.

Install line reactor or EMI filter if on shared transformer with VFDs.

Ensure adequate airflow—do not block ventilation slots.

Wire STO inputs to a certified safety relay(e.g.,Pilz,Sick).

Maintenance Tips:

Monitor drive temperature via WorkBench—sustained>70°C indicates cooling issues.

Check capacitor health every 5 years in high-temperature environments.

Keep firmware updated to benefit from tuning algorithm improvements.

Store spare units in dry,static-safe packaging—capacitors degrade if unused for>2 years.
