Kollmorgen S70102-NANANA Service-Ready Spare Part for Industrial Maintenance

Kollmorgen S70102-NANANA Service-Ready Spare Part for Industrial Maintenance

The Kollmorgen S70102-NANANA is a service-ready spare component sourced for the S700 series servo drive platform — one of the most widely deployed motion control architectures in precision manufacturing, packaging automation, and process control environments. When a servo drive fault triggers an unplanned shutdown, the ability to source a verified, pre-tested replacement unit directly determines how quickly production can resume. This listing provides maintenance engineers and procurement teams with a reliable, traceable supply path for the S70102-NANANA, backed by a 12-month warranty and pre-shipment functional verification.

Kollmorgen’s S700 servo drive family is engineered for demanding multi-axis motion applications. The S70102-NANANA variant is identified within the S700 naming convention by its power rating, feedback interface, and option configuration. Maintenance teams managing legacy S700 installations — particularly those operating beyond the original OEM support window — depend on third-party spare parts channels to sustain uptime without committing to full drive replacement or system redesign. This unit is supplied as an original-grade spare, suitable for direct board-level or module-level substitution within compatible S700 drive enclosures.

Maintenance Planning for Continuous Operation

Replacing the S70102-NANANA in an S700 servo drive installation is rarely an isolated task. Experienced maintenance engineers treat a servo drive fault as a signal to audit the surrounding electrical and control infrastructure. Before returning the axis to production, the following associated components should be inspected or replaced as part of a structured maintenance event:

DC Bus and Power Supply: The S700 drive’s internal DC bus capacitors degrade over time, particularly in high-cycle applications. When replacing the S70102-NANANA, inspect the 24 VDC logic supply module feeding the drive’s control board. A failing SITOP or equivalent 24 V power supply unit can cause intermittent drive faults that mimic encoder or communication errors. Verify output voltage stability under load before commissioning the replacement drive.

Feedback and Encoder Cabling: The S700 series supports resolver, EnDat 2.1/2.2, and SinCos encoder interfaces. Damaged or aged feedback cables — particularly shielded multi-core cables running through cable chains — are a leading cause of recurring drive faults after a spare part swap. Inspect the feedback connector at both the motor and drive ends, and replace any cable showing shield continuity loss or insulation cracking.

I/O and Digital Signal Modules: The S700 drive’s digital I/O interface connects to the machine’s safety relay chain, enable signals, and fault acknowledgment circuits. When the S70102-NANANA is replaced, verify that the enable input (ENPO), hardware enable, and STO (Safe Torque Off) wiring are intact. A faulty safety relay module or wiring fault on the STO circuit will prevent the replacement drive from enabling, leading to misdiagnosis of the new spare as defective.

Communication and Fieldbus Modules: S700 drives configured for CANopen, EtherCAT, or PROFIBUS DP operation rely on option communication cards. If the original drive failure involved a communication fault, inspect the fieldbus option module, termination resistors, and network topology before reinstalling. In EtherCAT topologies, a failed drive can disrupt the entire ring; confirm that the replacement drive’s node address and PDO mapping match the original configuration in the motion controller or PLC.

Motor Contactor and Braking Resistor: High-inertia applications using the S700 drive typically include an external braking resistor and a motor contactor for safe de-energization. Inspect the braking resistor for thermal damage and verify contactor contact resistance. A degraded braking resistor can cause DC bus overvoltage faults on the replacement drive during deceleration cycles, shortening its service life.

Terminal Blocks and Wiring Integrity: Phoenix Contact or equivalent spring-clamp terminal blocks used in S700 control cabinets should be inspected for loose connections, oxidation, and thermal discoloration. Loose signal wiring on analog reference inputs (±10 V speed/torque reference) or digital I/O terminals can introduce noise that degrades servo performance after the spare is installed.

HMI and Operator Panel: If the machine uses a Kollmorgen WorkBench-compatible HMI or a third-party operator panel for drive parameterization, verify that the parameter backup file matches the S70102-NANANA’s firmware version. Parameter mismatches between the backup and the replacement drive’s firmware can cause tuning errors or axis instability at startup.

Site Replacement Workflow

Step 1 — Isolation and Lockout: De-energize the S700 drive following LOTO procedures. Discharge the DC bus (minimum 5-minute wait after power-off; verify with a calibrated voltmeter before touching internal components).

Step 2 — Parameter Backup: If the original drive is still partially functional, connect via Kollmorgen WorkBench software and export the full parameter set. Save the backup file with the machine ID, axis number, and date. If the drive is non-responsive, retrieve the parameter backup from the machine’s PLC or motion controller memory, or from your maintenance management system.

Step 3 — Hardware Verification: Confirm that the S70102-NANANA replacement matches the original unit’s hardware index and option configuration. Check the label on the original drive for the hardware revision code. Mismatched hardware revisions may require firmware updates before the parameter file can be loaded.

Step 4 — Installation and Wiring: Install the replacement S70102-NANANA in the original mounting position. Reconnect all power, feedback, I/O, and communication cables. Torque all terminal screws to specification. Verify shield grounding at the drive’s PE terminal.

Step 5 — Parameter Restore and Commissioning: Load the saved parameter file via WorkBench. Perform a motor identification run if the firmware requires it. Verify encoder feedback signal quality in the WorkBench oscilloscope view before enabling the axis under load.

Step 6 — Functional Test: Run the axis through its full motion profile at reduced speed. Monitor DC bus voltage, motor current, and position error. Confirm that all safety functions (STO, SS1) operate correctly before returning the machine to production.

This structured replacement workflow minimizes the risk of repeat failures and ensures that the replacement S70102-NANANA is commissioned correctly, reducing unplanned downtime on subsequent shifts.

Spare Parts Support FAQ

Q1: What is the warranty coverage for the S70102-NANANA spare part?
All S70102-NANANA units supplied through this listing carry a 12-month warranty from the date of shipment. The warranty covers functional defects identified under normal operating conditions consistent with the S700 series application environment. Each unit undergoes pre-shipment functional verification before dispatch. Warranty claims are supported by our technical team; contact sale@ninermas.com with the order reference and fault description.

Q2: How do I confirm compatibility between the S70102-NANANA and my existing S700 installation?
Compatibility depends on the hardware revision, firmware version, and option configuration of your existing S700 drive. Before ordering, provide the full nameplate data from your original unit — including the hardware index suffix and any option codes — to our technical team. We will cross-reference against our inventory to confirm a compatible match. Do not rely solely on the base part number; S700 variants with different feedback or communication options are not interchangeable without reconfiguration.

Q3: Can you support long-term or blanket purchase orders for S700 series spare parts?
Yes. We support scheduled delivery agreements and blanket purchase orders for maintenance teams managing multiple S700 installations or planning annual shutdown stock. Long-term supply arrangements can be structured around your planned maintenance calendar, with agreed lead times and pricing. Contact sale@ninermas.com to discuss volume requirements and delivery scheduling.

Q4: What documentation is provided with the S70102-NANANA shipment?
Each shipment includes a packing list with the part number, serial number (where available), and shipment date. A test report confirming pre-shipment functional verification is included on request. For customs and import purposes, a commercial invoice with HS code classification is provided. If your procurement process requires a certificate of conformance or material traceability documentation, please specify this requirement at the time of order.
