Technical Introduction
OMRON 3F88M-115 is a legacy one-axis positioning unit for the OMNUC N115 series.
The unit is intended for motion applications where controlled positioning of a single servo axis is required. OMRON’s official product page classifies 3F88M-115 under motion/drive and position-control products and identifies it as an OMNUC N115 Series One-Axis Positioner. OMRON also provides an English Servo Positioner User’s Manual covering the 3F88M-115A/MPG/F configuration. The product is no longer orderable through OMRON, with the official page recording an order-end date of March 2003, making verified replacement inventory relevant for plants maintaining older machinery.

Field Engineer’s Tech Notes
- Do not treat 3F88M-115 as a current-generation servo controller. This is a discontinued OMNUC N115 product. Before replacement, confirm the installed servo motor, drive amplifier, feedback arrangement, and positioning parameters. A newer OMRON motion controller may require a control-system migration rather than a direct plug-in substitution.
- Back up the machine parameters before changing the positioner. For a legacy positioning system, accumulated position data, origin settings, acceleration/deceleration parameters, and axis-specific configuration can be just as important as the hardware itself. Record the existing setup before removing the failed unit.

Adaptive QA & Testing Protocol
Incoming QA for 3F88M-115 includes exact model verification, front-panel and housing inspection, connector inspection, nameplate recording, and comparison with the existing N115 unit.
For functional testing, the appropriate setup should reproduce the one-axis positioning function rather than treating the unit as a generic PLC module. The test sequence should verify power-up behavior, controller status, positioning commands, servo-axis response, and repeat positioning accuracy using a compatible N115/OMNUC test configuration.
Because this is a discontinued product, firmware/configuration compatibility should also be checked before shipment. Inspection photographs, test reports, and available test videos can be provided upon request.
Buyer’s FAQ
Q: Is OMRON 3F88M-115 still manufactured?
A: No. OMRON identifies the 3F88M-115 as a discontinued product and records an order-end date of March 2003.
Q: What type of controller is 3F88M-115?
A: It is an OMNUC N115 Series one-axis positioner used for motion and servo positioning applications.
Q: Can another OMRON position controller directly replace it?
A: Not necessarily. Servo amplifier compatibility, feedback type, machine I/O, positioning method, stored parameters, and mechanical integration must be checked before selecting a replacement.
Q: Can a refurbished or New Surplus unit be supplied?
A: Depending on available stock, replacement inventory may be offered as New Surplus (NSFP), used/tested, or refurbished. The exact condition and warranty should be stated on the quotation.
