Technical Specifications

Note: Electrical parameters specific to individual drive ratings (voltage class, current capacity) vary by host drive configuration. Confirm compatibility with your drive nameplate data before ordering. DriveKNMS technical staff can assist with cross-referencing.

Solving the Discontinued Hardware Crisis

The Yaskawa G7 and F7 series were workhorses of industrial automation through the 1990s and 2000s. Installed in steel mills, paper lines, water treatment facilities, chemical plants, and automotive body shops worldwide, these drives were specified for their robustness and their deep integration with plant-level SCADA and DCS architectures — including systems built on Honeywell TDC 3000, ABB MasterPiece 200/1, and Siemens S5 platforms. Replacing the drive is not simply a matter of swapping hardware. The control logic, speed references, analog I/O scaling, and fault interlock wiring are all calibrated to the existing drive's parameter set. A new-generation drive requires full re-engineering of that interface layer.

The YPHT11017-1A is the central processing board of the G7/F7 control architecture. It handles speed reference processing, PID regulation, fault detection logic, and communication with operator keypads and external control systems. When this board fails — typically due to electrolytic capacitor degradation, power surge damage, or firmware corruption — the drive becomes non-functional. There is no workaround. The board must be replaced.

For plant managers facing pressure to retire aging automation assets, the calculus is straightforward: a verified replacement board extends the operational life of the entire drive system by 5 to 10 years at a fraction of the cost of a forced upgrade. That window is sufficient to plan a controlled, budgeted migration on your schedule — not the schedule imposed by an unplanned failure.

Practical asset protection strategy for facilities running legacy Yaskawa G7/F7 drives:

Condition & Reliability Assurance

Every YPHT11017-1A unit processed by DriveKNMS passes a structured 5-stage quality protocol before it is offered for sale. This process is designed specifically for the failure modes common to boards of this age and design generation:

• Stage 1 – Visual and Physical Inspection: Full board examination under magnification. Pin corrosion, solder joint cracking, burnt components, and PCB delamination are grounds for rejection at this stage.
• Stage 2 – Electrolytic Capacitor Assessment: Capacitance and ESR (equivalent series resistance) measurement on all electrolytic capacitors. Capacitors showing degradation beyond 20% of rated capacitance or elevated ESR are replaced with equivalent-specification components.
• Stage 3 – Firmware Version Verification: Firmware version is confirmed and documented. Boards with corrupted or mismatched firmware versions are flagged and either re-flashed to the correct version or quarantined.
• Stage 4 – Functional Bench Test: Board is tested in a compatible drive chassis under controlled load conditions. Key functions — speed reference response, fault relay operation, keypad communication — are verified against factory behavior.
• Stage 5 – Final Documentation: Each board ships with a condition report noting inspection findings, capacitor replacement records (if any), firmware version, and test results.

Key Features for System Maintenance

How do I know the board is genuine Yaskawa and not a counterfeit?
All boards are inspected for authentic Yaskawa markings, PCB layer construction, and component sourcing consistent with factory production. Boards that show signs of remarking or non-OEM PCB fabrication are rejected. We do not sell boards we cannot authenticate.

Should I buy more than one unit?
For any facility running more than two G7/F7 drives, holding at least one spare YPHT11017-1A in inventory is a defensible maintenance decision. The part is no longer manufactured. Each unit sold from the secondary market reduces the global available pool. Prices for verified units will increase as supply contracts. Purchasing a spare now is a lower-cost option than sourcing one under emergency conditions.
