Product Overview

KOLLMORGEN S71262-NANANA Ruggedized Servo Drive for Harsh Environments

The KOLLMORGEN S71262-NANANA is a high-performance servo drive from the renowned AKD Series, engineered to deliver precise motion control and unwavering reliability in the most demanding industrial environments. Designed for continuous operation under conditions of elevated temperature, high humidity, airborne particulates, mechanical vibration, and intense electromagnetic interference, this unit is a cornerstone component for engineers and procurement specialists who cannot afford downtime in critical production systems.

Built on KOLLMORGEN’s proven AKD platform, the S71262-NANANA integrates advanced current-loop control, real-time auto-tuning, and multi-protocol communication support, making it a versatile and future-proof choice for both new installations and direct replacement of aging servo drive infrastructure. Its compact, DIN-rail-compatible form factor allows seamless integration into existing control cabinets without structural modification, reducing commissioning time and total cost of ownership.

In high-vibration environments such as mining conveyors, steel rolling mills, and offshore drilling platforms, the S71262-NANANA maintains stable closed-loop performance where lesser drives fail. Its robust internal architecture suppresses conducted and radiated EMI, protecting co-located equipment including Siemens SIMATIC S7-300/S7-400 PLCs, Rockwell Allen-Bradley ControlLogix I/O modules, and Schneider Electric Modicon M340 DCS controllers from signal corruption. This makes it an ideal companion in mixed-vendor control architectures where signal integrity across the backplane is non-negotiable.

The drive’s thermal management system is rated for ambient operating temperatures up to 40 °C (with derating to 55 °C), and its sealed enclosure design resists ingress of fine metallic dust and coolant mist — conditions routinely encountered in CNC machining centers, automotive body-in-white welding lines, and food-grade processing facilities. When paired with KOLLMORGEN AKM Series servo motors and AKD-N distributed node drives, the S71262-NANANA forms a fully integrated motion network capable of synchronizing multiple axes with sub-millisecond latency.

For system architects specifying safety-rated motion control, the S71262-NANANA supports STO (Safe Torque Off) functionality in compliance with IEC 62061 and ISO 13849-1 PLd/SIL 2 requirements. This eliminates the need for external safety contactors in many applications, simplifying cabinet wiring and reducing the component count in safety relay circuits. When integrated with a Pilz PNOZ safety relay or a Siemens SIRIUS 3SK safety module, the STO channel provides a certified, auditable safety path that satisfies machine directive requirements across EU and international markets.

Communication flexibility is a defining strength of the AKD platform. The S71262-NANANA supports EtherCAT, CANopen, and Modbus TCP/IP, enabling direct integration with a broad range of industrial fieldbus architectures. Whether your control system relies on a Beckhoff CX series EtherCAT master, a Yaskawa MP3300 machine controller, or a legacy CANopen network, this drive adapts without gateway hardware. Its onboard I/O — including digital inputs for homing, limit switches, and registration triggers — further reduces external terminal block and wiring complexity.

From a procurement standpoint, TOPNLMS maintains verified stock of the KOLLMORGEN S71262-NANANA, sourced through authorized supply channels and subject to incoming inspection prior to dispatch. Every unit undergoes functional verification including power-on self-test, communication handshake confirmation, and parameter integrity check before shipment. This ensures that replacement units arrive ready for immediate commissioning, minimizing mean time to repair (MTTR) in unplanned outage scenarios. All units are covered by a 12-month warranty against manufacturing defects, with technical support available throughout the warranty period.

Whether you are maintaining a continuous petrochemical process line, upgrading a water treatment SCADA-controlled pump station, or replacing a failed axis drive in a glass tempering furnace, the S71262-NANANA delivers the performance, safety compliance, and supply chain reliability that industrial operations demand. TOPNLMS ships globally from Xiamen, China, with DHL Express, FedEx International Priority, and sea freight options available to suit your logistics requirements and budget.

Comprehensive Protection Solutions

The S71262-NANANA is rarely deployed in isolation. In a fully specified control cabinet, it operates alongside complementary components that together form a resilient, safety-rated automation system. KOLLMORGEN AKD-N distributed servo nodes extend the motion network across the machine frame without additional drive enclosures, reducing cabinet footprint. KOLLMORGEN AKM Series servo motors, matched to the S71262-NANANA’s current and voltage ratings, deliver the torque density and encoder resolution required for precision positioning in packaging and semiconductor handling applications.

On the power conditioning side, a Phoenix Contact QUINT POWER 24 VDC industrial power supply provides stable logic-rail voltage to the drive’s control board, while a Murr Elektronik MICO+ electronic circuit breaker protects individual load branches from overcurrent faults without nuisance tripping. For surge and transient protection at the cabinet entry point, a Dehn DEHNguard surge protective device clamps voltage spikes induced by nearby variable frequency drives — such as the ABB ACS880 or Danfoss FC302 — that share the same distribution panel.

Communication integrity is maintained through a Moxa EDS-308 managed industrial Ethernet switch, which segments the EtherCAT motion network from the plant-level SCADA Modbus TCP/IP backbone, preventing broadcast storms from disrupting real-time axis synchronization. Safety circuit integrity is enforced by a Pilz PNOZmulti 2 configurable safety controller, which monitors the STO input of the S71262-NANANA alongside E-stop buttons, light curtains, and door interlock switches across the machine cell. Terminal connectivity within the cabinet is handled by Phoenix Contact CLIPLINE complete spring-cage terminal blocks, which maintain reliable contact under the vibration loads typical of press and stamping applications.

Application in Critical Infrastructure

In oil and gas upstream and midstream facilities, the KOLLMORGEN S71262-NANANA drives wellhead pump jacks, pipeline compressor auxiliary systems, and valve actuators in classified hazardous areas (Zone 2 / Division 2) when installed within appropriately rated enclosures. Its STO function satisfies the emergency shutdown (ESD) requirements mandated by IEC 61511 functional safety standards for process industries.

In mining and mineral processing, the drive controls conveyor belt tensioning systems, ore crusher feed regulators, and flotation cell agitators — all applications characterized by high inertia loads, frequent starts, and exposure to silica dust and acidic moisture. The drive’s robust EMI filtering prevents interference from high-power variable speed drives operating on the same MCC bus.

In power generation and utilities, including coal-fired, gas turbine, and hydroelectric plants, the S71262-NANANA is deployed in turbine governor auxiliary actuators, cooling tower fan drives, and boiler feed pump speed control systems. Its wide input voltage tolerance accommodates the voltage fluctuations inherent in plant auxiliary power systems.

In water and wastewater treatment, the drive manages submersible pump motor control, sludge dewatering press drives, and UV disinfection system conveyor feeds — environments where continuous 24/7 operation, corrosion resistance, and remote SCADA diagnostics via Modbus TCP/IP are essential operational requirements.

In metallurgy and heavy industry, including steel rolling mills and aluminum smelters, the S71262-NANANA withstands radiated heat from furnace proximity, high-frequency electrical noise from arc furnaces, and mechanical shock from rolling mill stands — conditions that validate its selection as a long-term, low-maintenance motion control solution.
