Product Overview

YASKAWA YPHT31033-1-1 73600-A0101 Drive Control PCB: Seamless Replacement & Upgrade Solution for YPHT Series

When a YASKAWA YPHT Series AC drive trips offline on a production line, every minute of unplanned downtime translates directly into lost output and escalating maintenance costs. The YASKAWA YPHT31033-1-1 73600-A0101 Drive Control PCB is the factory-matched control board engineered for direct, drop-in replacement inside YPHT Series variable-frequency drives. Whether you are executing a planned preventive-maintenance swap, recovering from a catastrophic board failure, or modernizing an aging drive system without replacing the entire drive cabinet, this PCB delivers the electrical compatibility, firmware alignment, and mechanical fit your retrofit demands.

TOPNLMS maintains verified stock of the YPHT31033-1-1 73600-A0101 sourced from authorized supply channels. Every unit undergoes incoming inspection and functional verification before dispatch. Orders placed before the daily cut-off ship the same business day from our Xiamen warehouse, with DHL Express, FedEx International Priority, and sea-freight consolidation available to match your project timeline and budget.

Seamless Upgrade Solutions

A drive control board replacement rarely occurs in isolation. In practice, field engineers performing a YPHT Series retrofit often find that adjacent components have accumulated equal wear hours and benefit from simultaneous renewal. During the same maintenance window, it is common to inspect and replace the YASKAWA YPHT Series gate driver board that sits downstream of the control PCB, since gate-drive faults frequently originate from degraded IGBT trigger signals rather than the control logic itself. The YASKAWA YPHT Series power supply board (internal SMPS) is another high-priority item: a marginal SMPS rail voltage causes intermittent control resets that mimic control-board failure, so replacing both boards together eliminates the diagnostic ambiguity.

On the communication side, many YPHT Series installations interface with a Siemens S7-300 or S7-400 PLC via PROFIBUS-DP or Modbus RTU. If the site is migrating from a legacy S7-300 CPU 315-2 DP to a newer S7-1500 platform, the drive’s YASKAWA SI-P3/V PROFIBUS option card may need to be re-addressed and re-parameterized to match the new GSD file. Similarly, plants running Allen-Bradley ControlLogix or CompactLogix controllers over DeviceNet should verify that the YASKAWA SI-N3 DeviceNet option card firmware is current after the control board swap, as the option card communicates through the control PCB backplane.

For installations where the YPHT drive feeds a motor through a YASKAWA output reactor (ACR) or a dV/dt filter, these passive components are unaffected by the PCB swap and require no reconfiguration. However, if the site is also upgrading the upstream YASKAWA CIMR-series input reactor or replacing the EMC line filter to meet updated CE or UL emission standards, the control board replacement is the ideal time to perform that work concurrently, minimizing the number of drive power-down events.

Panel builders and system integrators modernizing a complete motor control center (MCC) will often pair the YPHT31033-1-1 73600-A0101 with a new YASKAWA DriveWizard Industrial programming cable (USB-to-RS422 or USB-to-RS232 adapter) to back up and restore drive parameters without relying on the keypad. A YASKAWA JVOP-182 USB Copy Unit or equivalent parameter copy keypad is equally effective for multi-drive sites where dozens of drives share identical parameter sets. Finally, if the control cabinet also houses a YASKAWA MP2300 or MP3300 machine controller coordinating multi-axis motion, verify that the motion program’s drive fault-handling logic is updated to reflect the new board revision before returning the system to automatic mode.

Retrofit Guidance FAQ

Q: Do I need to rewire any terminals after replacing the YPHT31033-1-1 73600-A0101?
No. The replacement PCB uses the identical OEM connector layout. All ribbon cables, discrete signal connectors, and control terminal wiring reconnect to the same positions without modification. Verify connector seating and locking tab engagement before powering up.

Q: Will my existing drive parameters be preserved?
The control PCB does not retain parameters internally in all revisions — parameters are stored in the keypad or an external copy unit. Before removing the failed board, use the YASKAWA JVOP keypad or DriveWizard software to upload and save the full parameter set. After installing the replacement board, download the saved parameters and perform a no-load test run to confirm correct operation.

Q: Is the Modbus RTU / MEMOBUS communication address retained after the swap?
The drive node address and baud rate are stored as drive parameters (typically H5-01 through H5-09 in YASKAWA parameter nomenclature). These are restored along with the full parameter upload. No changes to the PLC communication configuration or HMI tag mapping are required.

Q: Will the replacement board fit in the same physical space inside the drive enclosure?
Yes. The YPHT31033-1-1 73600-A0101 is manufactured to the same PCB footprint and uses the same mounting hole pattern as the original board. No mechanical modification to the drive chassis or cabinet is required.

Q: What fault codes typically indicate control board failure in YPHT Series drives?
Common indicators include persistent OC (overcurrent) faults with no load-side cause, CPF (control circuit fault) alarms, erratic keypad communication loss, and unexplained drive trips that clear only after a full power cycle. If these symptoms persist after checking the gate driver board and SMPS rail voltages, the control PCB is the primary suspect.

Q: Can this board be used as a cross-replacement for other YASKAWA drive series?
The YPHT31033-1-1 73600-A0101 is specifically designed for the YPHT Series. Cross-application to CIMR-G7, CIMR-F7, or other YASKAWA drive families is not recommended without factory confirmation, as connector pinouts and firmware compatibility differ between series.

Warranty Assurance

Every YASKAWA YPHT31033-1-1 73600-A0101 Drive Control PCB shipped by TOPNLMS is covered by a 12-month warranty from the date of shipment. Our warranty process is straightforward: if the board exhibits a verified manufacturing defect or functional failure within the warranty period under normal operating conditions, we will arrange a replacement unit or issue a credit — whichever resolves your production situation fastest.

Pre-shipment testing: Each board is visually inspected for component integrity, solder joint quality, and connector condition before packaging. High-value boards undergo additional electrical continuity checks.

Packaging: Boards are shipped in anti-static ESD bags, placed in foam-lined cartons, and double-boxed for international freight. Fragile and ESD-sensitive labels are applied to all outer packaging.

Shipping options: DHL Express (3–5 business days globally), FedEx International Priority, TNT Economy Express, and sea-freight consolidation for large orders. Tracking numbers are provided within 24 hours of dispatch.

After-sales support: Our technical team is available via email and phone to assist with installation questions, parameter restoration guidance, and fault diagnosis. We aim to respond to all technical inquiries within one business day.

Returns: Unused boards in original packaging may be returned within 30 days of receipt for a full refund. Boards that have been installed and exhibit a warranty-covered defect are handled on a case-by-case basis with priority given to minimizing your downtime.
