Kollmorgen S72402-NANANA-NA-225 Digital AC Servo Drive – High-capacity control for fast, precise motion

The Kollmorgen S700 family is built for applications where cycle times keep getting shorter and positioning has to be exact. The S72402-NANANA-NA-225 sits in that sweet spot—high continuous current, robust control loops, and the flexibility to run modern feedbacks and motors. From my experience, it’s a solid pick for multi-axis packaging machines, high-speed assembly, and indexers where you can’t afford drift or hunting. You might notice that the “NANANA” option string indicates no fieldbus card fitted, which typically suits standalone or analog-command architectures and keeps the BOM lean.

Order Process and Guarantees

• Express options: FedEx, UPS, DHL

Key Features

• High-performance control loops – Fast current/velocity/position control for tight tolerance moves and smooth low-speed creep.
• Wide motor compatibility – Drives synchronous servo, linear, and torque motors; works well with Kollmorgen AKM/AKM2G series and equivalents.
• Multi-feedback support – Typically supports resolver, TTL/HTL incremental, and single-cable smart encoders (e.g., Hiperface/EnDat/BiSS) depending on installed interface.
• Flexible command interfaces – Analog ±10 V, pulse/direction, and digital I/O make it easy to drop into legacy or hybrid controls. RS‑232 for commissioning is standard.
• Integrated safety (STO) – Safe Torque Off functionality to help meet machine safety requirements; in many cases certified up to SIL 2 / PL d on S700 platforms.
• Energy handling – DC bus sharing and internal brake chopper support; connect an external brake resistor for rapid decel without nuisance trips.
• Tuning tools – Auto-tuning and trace tools typically reduce setup time; helpful when swapping motors or increasing throughput.
• Global mains compatibility – Works on common industrial 3‑phase 50/60 Hz supplies (208–480 VAC class) with a separate 24 VDC control supply.
• EMC-ready design – Book-style chassis, shield clamp points, and filter/reactor options to meet cabinet EMC targets.

Application Fields

This model fits high-throughput machines where precision and uptime matter. Typical uses include:

• Packaging and labeling lines – fast indexing, electronic cams, and coordinated multi-axis motion.
• Electronics assembly – pick-and-place axes, gantries, and feeders requiring smooth micro-moves.
• Machine tools and grinding – accurate contouring and spindle/axis synchronization.
• Printing and web handling – tension control, register correction, dancer/diameter applications.
• Materials processing – cutting, bending, winding with tight speed and torque regulation.

A packaging OEM told us they cut tuning time by roughly 30% moving to the S700 tools and kept the same mechanicals—no need to redesign the cabinet.

Advantages & Value

• Reliability – Proven S700 platform with robust protection and thermal design; downtime is typically low when installed correctly.
• Compatibility – Works with common industrial encoders and Kollmorgen motors; simple to retrofit using ±10 V or step/direction control.
• Cost control – “NANANA” (no bus option) keeps cost down when a fieldbus isn’t necessary; option cards can be added later on compatible units.
• Commissioning speed – Auto-tune, oscilloscope traces, and parameter sets shorten setup, especially when cloning across axes.
• Support and lifecycle – Strong documentation and tooling; firmware updates and parameter backups help extend service life.

Installation & Maintenance

• Cabinet and ventilation – Mount vertically on a grounded backplate with unobstructed top/bottom airflow. Provide adequate clearance and keep ambient within spec.
• Power and wiring – Use correctly sized 3‑phase mains, separate 24 VDC control supply, and an external brake resistor where high regenerative energy is expected.
• EMC and grounding – Bond shields 360° at entry points, keep motor and encoder runs separate from mains, and use line filters/line reactors as needed to meet EMC.
• Safety – Wire STO per the manual and validate the safety function. Lock out/tag out before servicing. Verify contactor logic if used for Category 0 stops.
• Routine maintenance – Periodically clean filters and fans, check terminal torque, review fault logs, and update firmware when released by Kollmorgen.
• Tuning and calibration – Run auto-tune after mechanical changes; for dual-loop systems, ensure load encoder alignment and stiffness checks.

Quality & Certifications

• CE marking for relevant EMC and Low Voltage directives (typical for S700 series)
• UL/cUL recognition for industrial control equipment (model-dependent)
• RoHS compliant build on current production
• Manufacturer warranty: 12 months (365 days)

Recommended Supporting Components

• Kollmorgen AKM / AKM2G servo motors – Matched inertia and feedback options for S700; cable sets available.
• Kollmorgen brake resistor (BRC series) – Sized to the S72402’s chopper for aggressive deceleration profiles.
• Fieldbus option card (e.g., S7-ECAT, S7-CAN) – Add EtherCAT or CANopen on compatible S700 units when PLC integration is required.
• Mains input filter (KDF series) and 3‑phase line reactor – Helps meet EMC and reduce harmonics in sensitive installations.
• Shielded feedback and motor power cables – Reduce noise and improve encoder signal integrity over long runs.

If you’re migrating from a legacy analog drive, this variant keeps the wiring strategy straightforward. And if later you need networked control, it seems to be an easy path to add a fieldbus version on the S700 platform without reworking the whole machine concept.
