KOLLMORGEN S72402-NANANA Compact AC Servo Drive with EtherCAT and STO Safety

The KOLLMORGEN S72402-NANANA is a compact, high-response servo drive from Kollmorgen’s S700 series, designed to deliver precise motion control for low-to-mid power applications. Optimized for seamless integration with Kollmorgen’s AKM® servo motors, this 240V, 2A-rated amplifier supports real-time industrial networks like EtherCAT and includes built-in functional safety via Safe Torque Off (STO). With its plug-and-play configuration, advanced tuning algorithms, and robust I/O capabilities, the KOLLMORGEN S72402-NANANA enables fast commissioning and reliable performance in demanding automation environments.

Application Scenarios

In a high-speed pharmaceutical blister packaging line in Germany, frequent misfeeds and motor overheating plagued production uptime—until engineers replaced legacy drives with the KOLLMORGEN S72402-NANANA. Paired with an AKM21G motor, the KOLLMORGEN S72402-NANANA’s auto-tuning feature instantly adapted to dynamic load changes during film indexing, while its integrated STO ensured safe emergency stops without mechanical wear. Cycle times improved by 18%, and thermal shutdowns dropped to zero. For OEMs and end users alike, the KOLLMORGEN S72402-NANANA transforms motion complexity into operational simplicity.

Technical Principles and Innovative Values

Innovation Point 1: Adaptive Auto-Tuning with Load Inertia Estimation

The KOLLMORGEN S72402-NANANA uses real-time inertia identification to auto-adjust PID gains—eliminating manual tuning and ensuring optimal response even with variable payloads, such as in pick-and-place robots or web-guided conveyors.

Innovation Point 2: Native EtherCAT with Sub-100µs Cycle Time

Unlike drives requiring gateway modules, the KOLLMORGEN S72402-NANANA embeds a high-performance EtherCAT slave controller, enabling deterministic motion coordination across multi-axis machines with minimal jitter.

Innovation Point 3: Seamless AKM Motor Integration via Smart Feedback

When paired with Kollmorgen’s absolute encoders (e.g., Hiperface DSL® or EnDat), the KOLLMORGEN S72402-NANANA reads motor ID and calibration data automatically—preventing mismatch errors and accelerating setup.

Innovation Point 4: Energy Recovery & Low Heat Dissipation

Advanced PWM algorithms reduce switching losses, allowing the KOLLMORGEN S72402-NANANA to operate efficiently in confined panels—critical for compact OEM machinery where cooling space is limited.

Application Cases and Industry Value

At a U.S.-based label printing OEM, machine builders struggled with registration drift on narrow-web presses due to inconsistent servo response. After integrating the KOLLMORGEN S72402-NANANA with AKM22 motors on unwind/rewind axes, registration accuracy improved to ±0.05 mm—exceeding customer specs. The drive’s high bandwidth compensated for tension fluctuations at 300 m/min, while EtherCAT synchronization eliminated skew between print and die-cut stations. Customer feedback highlighted “plug-and-run” commissioning: full axis validation took under 20 minutes using Kollmorgen’s WorkBench software.

In another case, a Japanese semiconductor wafer handler adopted the KOLLMORGEN S72402-NANANA for its Z-lift mechanism. The integrated STO function met SEMI S2 safety requirements, and the drive’s compact footprint allowed installation inside the robot base—freeing valuable cleanroom floor space.

Installation, Maintenance, and Full-Cycle Support

The KOLLMORGEN S72402-NANANA is engineered for rapid deployment: its standardized connectors, clear status LEDs (Power, Ready, Fault, STO), and intuitive DIP switches simplify field wiring and diagnostics. Mounting on a standard 35 mm DIN rail allows quick replacement during maintenance windows. The drive operates reliably in ambient temperatures up to 45°C and features overvoltage, overcurrent, and overtemperature protection—minimizing unexpected failures.

We provide comprehensive lifecycle support for the KOLLMORGEN S72402-NANANA, including pre-shipment validation (full functional test with AKM motor simulation), firmware verification, and compatibility checks with your motion architecture. Every unit is tested for STO response time (<10 ms), EtherCAT communication integrity, and thermal stability under load. Backed by a 12-month warranty and access to Kollmorgen-certified application engineers, we ensure your motion system performs at peak precision from day one—and for years to come.
