Kollmorgen S70102-NANANA Original Industrial Spare AKD Compatible

Product Overview

Kollmorgen S70102-NANANA Original Industrial Spare AKD Compatible: System Stability & Maintenance Value

The Kollmorgen S70102-NANANA is a genuine AKD Series EtherCAT Servo Drive rated at 3A continuous output current, designed for 120/240VAC single-phase or three-phase input. In modern manufacturing and process automation environments, servo drive availability is a direct determinant of production uptime. When an AKD drive fails on the line, every minute of unplanned downtime translates into measurable production loss. Stocking the S70102-NANANA as a verified original spare eliminates the lead-time risk associated with emergency procurement and ensures your maintenance team can execute a same-shift replacement without waiting on supply chain delays.

The AKD platform from Kollmorgen is widely deployed across CNC machining centers, packaging lines, semiconductor handling equipment, robotic assembly cells, and precision motion stages. The S70102-NANANA variant, with its EtherCAT fieldbus interface, integrates directly into EtherCAT master controllers and distributed motion networks, making it a drop-in replacement for failed units without requiring network reconfiguration or parameter re-mapping when the drive backup file is retained.

Critical Technical Specs

Preventive Maintenance Strategy

A servo drive failure rarely occurs in isolation. In a typical AKD-based motion axis, the drive operates as part of an integrated electrical and mechanical chain. When scheduling a planned replacement of the S70102-NANANA, experienced maintenance engineers use the opportunity to inspect and, where necessary, pre-stock adjacent components that share the same service interval or failure mode.

The AKD servo motor feedback cable (Kollmorgen CFB series or equivalent shielded SFD3 cable) is the most common co-failure item. Connector wear, insulation fatigue, and shield continuity loss at the motor end are frequent root causes of drive fault codes. Replacing the feedback cable at the same time as the drive eliminates a second unplanned outage within weeks of the first repair.

The 24VDC control power supply feeding the AKD logic board should be verified for output ripple and voltage stability. A degraded MEAN WELL or Phoenix Contact PSU can cause intermittent drive enable faults that are misdiagnosed as drive failures. Stocking a spare 24VDC DIN-rail PSU alongside the S70102-NANANA is a low-cost insurance policy for the entire control cabinet.

For multi-axis systems, the AKD EtherCAT daisy-chain patch cables (Cat5e shielded, M12 or RJ45 terminated) connecting drives in the EtherCAT ring should be inspected for connector seating and cable routing stress. A single degraded cable can cause the entire EtherCAT segment to drop, taking multiple axes offline simultaneously.

The Kollmorgen AKD-B or AKD-T bus capacitor module (shared DC bus accessory) used in multi-axis cabinet configurations should be checked for capacitance degradation if the installation is more than five years old. Capacitor aging is a silent contributor to DC bus overvoltage faults during deceleration.

In the same control cabinet, the 24VDC I/O terminal blocks and relay output modules (Phoenix Contact or Weidmüller series) used for drive enable, fault reset, and brake control signals should be inspected for contact oxidation and terminal torque. Loose terminals on the STO (Safe Torque Off) circuit are a common cause of nuisance safety faults.

If the machine uses a Kollmorgen AKD-N distributed servo node or a KAS (Kollmorgen Automation Suite) motion controller as the EtherCAT master, verify the firmware version compatibility between the replacement S70102-NANANA drive and the master controller before installation. Mismatched firmware can prevent the drive from entering operational state on the EtherCAT network.

For facilities running legacy Kollmorgen S300 or S700 series drives alongside AKD units, maintaining a cross-reference spare list that includes both S70102-NANANA (AKD) and equivalent S700 series modules ensures that mixed-generation lines can be serviced without separate procurement cycles. The AKD platform is the designated long-term replacement path for S300/S700 installations.

Finally, the motor brake resistor (external braking resistor, typically 100Ω–200Ω, 100W–200W depending on inertia load) should be inspected for thermal discoloration and resistance drift. A degraded braking resistor causes DC bus overvoltage faults during fast deceleration cycles and is frequently overlooked during routine drive replacement.

Strategic Replacement Solutions

The S70102-NANANA directly replaces failed AKD EtherCAT drives in existing Kollmorgen motion systems without requiring mechanical modifications, wiring changes, or EtherCAT network reconfiguration — provided the replacement drive is loaded with the original drive parameter backup file via WorkBench software. This plug-and-restore capability is the primary reason maintenance teams specify original Kollmorgen AKD spares rather than third-party alternatives: parameter compatibility is guaranteed, and commissioning time is reduced to under 30 minutes in most cases.

For facilities transitioning from older Kollmorgen S700 or Servostar 600 series drives, the AKD S70102-NANANA represents the manufacturer-recommended upgrade path. The AKD platform offers superior EtherCAT cycle time performance (250µs minimum), integrated functional safety (STO, SBC per IEC 62061), and a longer active production lifecycle compared to legacy series, reducing the total cost of ownership over a 10-year maintenance horizon.

Procurement teams should note that original AKD drives sourced through authorized channels include full traceability documentation, factory test records, and are eligible for Kollmorgen’s extended support programs. Each unit shipped from TOPNLMS is inspected and function-tested prior to dispatch, with a 12-month warranty covering manufacturing defects and operational failures under normal industrial use conditions.

Support FAQ

Q1: Is the S70102-NANANA compatible with my existing AKD EtherCAT system without reconfiguration?
Yes. The S70102-NANANA is a direct form-fit-function replacement for any AKD EtherCAT drive of the same current rating. Restore your saved WorkBench parameter file to the replacement drive and the axis will resume operation with identical tuning and motion profiles. No EtherCAT network reconfiguration is required.

Q2: What is the warranty coverage and what does it include?
All units carry a 12-month warranty from the date of shipment. The warranty covers manufacturing defects and functional failures under normal operating conditions. It does not cover damage resulting from incorrect installation, overvoltage events, or operation outside rated specifications. Our technical team provides pre-shipment function testing documentation upon request.

Q3: How should I manage AKD spare inventory for a multi-axis production line?
Industry best practice for critical motion axes is to maintain a minimum of one spare drive per five installed axes, with a floor of one spare per line regardless of axis count. For high-utilization lines running 24/7, a 1:3 ratio is recommended. The S70102-NANANA’s compact form factor and long shelf life (10+ years in proper storage conditions) make it cost-effective to hold as a strategic buffer spare.

Q4: Can I verify compatibility before committing to a purchase?
Yes. Provide your existing drive nameplate data (full part number, firmware version, and motor model) to our technical team at [email protected]. We will confirm compatibility and, where applicable, advise on any firmware alignment steps required before installation. Expedited shipping options are available for emergency breakdown situations.
