Kollmorgen S71262-NANANA System-Ready Servo Drive for S700 Series Architecture

Kollmorgen S71262-NANANA System-Ready Servo Drive for S700 Series Architecture: Control System Coordination and Upstream-Downstream Synchronization

The Kollmorgen S71262-NANANA is a high-performance servo drive engineered for seamless integration within the S700 Series control architecture. Rather than functioning as a standalone motion component, this drive is designed from the ground up to operate as a coordinated node within a layered industrial automation system — spanning the control layer, I/O layer, network layer, power layer, human-machine interface layer, and execution layer. Its role in the system is to translate digital command signals from the upper control layer into precise, real-time mechanical motion at the execution layer, while maintaining full bidirectional communication with supervisory controllers and diagnostic platforms.

In modern industrial automation environments — whether applied to manufacturing assembly lines, power generation facilities, petrochemical processing plants, water treatment infrastructure, mining operations, metallurgical production, packaging lines, or continuous process control systems — the servo drive is not merely a power conversion device. It is a critical architectural element that determines system responsiveness, positional accuracy, fault tolerance, and long-term maintainability. The S71262-NANANA fulfills this role within the Kollmorgen S700 ecosystem with a level of integration depth that reduces commissioning time, simplifies diagnostics, and supports scalable system expansion.

Coordinated Control System Design

The S71262-NANANA achieves its full performance potential when deployed as part of a coordinated S700-based control system. At the control layer, it receives motion commands from a Kollmorgen AKD-series master controller or a third-party PLC such as a Siemens S7-300/S7-400 or Allen-Bradley ControlLogix platform via a standardized fieldbus interface. The drive interprets these commands in real time and executes them at the motor shaft with sub-millisecond latency, ensuring that the mechanical execution layer remains tightly synchronized with the supervisory control logic.

At the I/O layer, the S71262-NANANA interfaces with digital and analog I/O modules — such as Kollmorgen S700 expansion I/O cards or third-party I/O terminals — to receive limit switch signals, home position inputs, and external enable/disable commands. This bidirectional I/O integration allows the drive to participate in safety interlocks and sequence logic without requiring additional relay logic or intermediate signal converters.

At the network layer, the drive supports multi-node fieldbus topologies. In a typical S700 architecture, multiple S71262-NANANA drives may be daisy-chained on a single CANopen or EtherCAT segment, with each node addressed independently by the master controller. This topology reduces wiring complexity, supports real-time synchronization across multiple axes, and enables centralized fault monitoring from a single SCADA or HMI terminal.

At the power layer, the S71262-NANANA is designed to operate in conjunction with Kollmorgen S700 series regenerative power supplies and DC bus sharing modules. In multi-axis cabinet designs, shared DC bus architecture allows braking energy from decelerating axes to be redistributed to accelerating axes, reducing net energy consumption and minimizing heat dissipation within the control cabinet. This is particularly relevant in high-cycle applications such as packaging machinery, press lines, and robotic welding cells.

At the human-machine interface layer, the drive integrates with Kollmorgen WorkBench software for parameter configuration, auto-tuning, oscilloscope diagnostics, and firmware management. In larger system architectures, WorkBench can be networked to monitor multiple S700 drives simultaneously, providing maintenance engineers with a unified view of drive health, fault history, and performance trends. This capability significantly reduces mean time to repair (MTTR) in production environments where downtime is costly.

At the execution layer, the S71262-NANANA drives Kollmorgen AKM-series or TBM-series servo motors, providing closed-loop torque, velocity, and position control with high dynamic response. The drive’s Smart Feedback Device (SFD) interface eliminates the need for separate encoder cables on compatible motors, simplifying installation and reducing potential failure points in the feedback signal chain. For legacy motor installations, the drive also supports standard incremental and absolute encoders, as well as resolver feedback, ensuring backward compatibility within mixed-generation system architectures.

In redundant system designs, the S71262-NANANA can be deployed in hot-standby or cold-standby configurations alongside a backup drive unit. The system controller monitors drive health via the fieldbus interface and can initiate automatic failover in the event of a drive fault, maintaining production continuity in critical applications such as power plant auxiliary systems, water treatment pump stations, and continuous chemical process lines.
