YASKAWA YPHT11017-1A – Drive Main Control Board | Varispeed / G7 / F7 Series Platform
Engineering Background: The YPHT11017-1A is the central intelligence board of YASKAWA’s high-performance AC drive family. Designed to manage PWM signal generation, speed reference processing, and real-time fault diagnostics, this board is the operational core that determines drive reliability in demanding industrial environments. Engineers specifying replacement or spare boards for YASKAWA Varispeed, G7, or F7 series drives rely on this exact part number to restore OEM-level performance without drive replacement.
Product Positioning: This is a direct OEM-equivalent main control PCB sourced through verified industrial channels. It is not a third-party clone or remanufactured substitute. Konmask.com supplies this board to maintenance engineers, system integrators, and MRO procurement teams requiring traceable, spec-accurate components with short lead times.

System Architecture & Signal Flow
The YPHT11017-1A sits at the top of the drive’s internal hierarchy. It receives analog and digital reference signals from the terminal board, processes speed/torque commands via its onboard DSP, and outputs PWM gate signals to the gate driver board. Simultaneously, it monitors DC bus voltage, output current, heatsink temperature, and encoder feedback (where applicable). Fault events are logged to non-volatile memory and communicated to the operator panel via the internal serial bus.
Signal Flow Summary: Terminal Board → YPHT11017-1A (Main Control) → Gate Driver Board → IGBT Power Module → Motor Output

Technical FAQ
Q: Is YPHT11017-1A compatible with all YASKAWA G7 drive ratings?
A: Compatibility depends on the specific drive kW rating and firmware revision. Please provide your full drive model number (e.g., CIMR-G7A4037) for confirmation before ordering.
Q: Can I replace just the control board without replacing the entire drive?
A: Yes. The main control board is a field-replaceable unit (FRU) in YASKAWA drives. Board swap typically requires only basic ESD precautions and a screwdriver. Parameter backup via the operator panel is recommended before replacement.
Q: Will my existing drive parameters be retained after board replacement?
A: Parameters are stored on the operator panel (keypad) in most G7/F7 configurations. If you have a parameter backup, they can be restored after board swap. Konmask recommends backing up parameters before any board-level service.
Q: What is the lead time if the board is not in stock?
A: Typical lead time for sourced units is 3–7 business days. Contact support@konmask.com for real-time availability.
Q: Do you provide a warranty?
A: Yes. All boards carry a 90-day functional warranty covering manufacturing defects. Warranty claims require return of the defective unit with fault description.
