Yaskawa GA800 A.132 Fault — What It Means
The code A.132 does not appear in verified Yaskawa GA800 documentation. GA800 drives typically display faults in formats like oC (overcurrent), ov (overvoltage), CPF32 (control circuit error), or oFA32 (option card SUM check error), not decimal-style codes such as A.132. The display you see may be a keypad status message, an option-card diagnostic code, a parameter address, or a transcription issue. It is also possible the code belongs to a different Yaskawa drive family or a third-party HMI connected to the GA800.
Before troubleshooting, confirm the exact characters shown on the drive keypad or operator, including any prefix, suffix, or punctuation. Check whether the message appears on the main drive display or on an add-on keypad or communications card. Consult the GA800 technical manual alarm table for your firmware revision to match the code precisely. If the code persists and is not documented, contact Yaskawa technical support with the drive model number, serial number, and a photo of the display.
Before You Replace Anything
Technicians sometimes replace the entire drive when the actual fault is a loose or corrupted option card. Before ordering a new drive, power down, reseat all option cards and ribbon cables, and clear the fault history to see if the code recurs.
Common Causes
- Incorrect code transcription (~35%) The display may show a parameter address (e.g., A1-32) or a different alphanumeric fault that was misread as A.132.
- Option card communication fault (~25%) An add-on communications or I/O card may report a checksum or connection error in a format not listed in the main drive manual.
- Keypad or HMI status message (~20%) A third-party operator or programming keypad may display its own internal status codes that differ from the drive’s native alarm list.
- Firmware or parameter mismatch (~15%) An older or custom firmware build may use a fault-code format not documented in the current GA800 manual.
- Control board hardware fault (~5%) A corrupted EEPROM or damaged microprocessor may display garbled or undocumented codes.
Quick Diagnosis
Answer these to narrow it down fast.
Does the drive keypad show a hyphen or space in the code (for example A1-32 or A 132)?
No: Proceed to check whether an option card or external operator is installed.
Is a communications card, encoder card, or external keypad installed in the drive?
No: The code may be a main-board fault or a firmware issue. Note the exact drive model, serial number, and firmware version, then contact Yaskawa technical support.
Can you clear the fault by pressing the RESET button or cycling power?
No: A persistent undocumented code usually indicates a control-board hardware failure or corrupted memory. Replace the control board or drive after confirming with the manufacturer.
Step-by-Step Fix
- Power down and lock out the drive at the main disconnect to safely inspect the keypad and option slots.
- Photograph the display exactly as shown, capturing all characters, decimal points, hyphens, and any annunciators or LED indicators.
- Check the drive nameplate for the complete model number (for example CIMR-G7U…) and note the firmware revision shown in the keypad setup menu (typically parameter A1-00 or similar).
- Remove any option cards by sliding them out of the control-board slots, then inspect the card edge connectors and drive backplane for corrosion or bent pins.
- Restore power without the option cards and observe whether the code clears or changes. If it disappears, reinstall cards one at a time to isolate the faulty module.
- Consult the GA800 technical manual alarm table for your firmware version, searching for codes that resemble A.132 in format or meaning.
- Contact Yaskawa technical support with the drive serial number, firmware revision, a photo of the display, and any recent parameter changes or option-card installations to obtain an official interpretation of the code.
Parts Often Needed
| Part | Notes |
|---|---|
| Yaskawa GA800 control board | Amazon | Factory replacement PCB if the main board is confirmed faulty. Match the drive horsepower and voltage rating. |
| Yaskawa option card (communications or I/O) | Amazon | Replace only if the fault isolates to a specific add-on module. Verify card part number and firmware compatibility. |
When to Call a Pro
Call a qualified industrial-controls technician or Yaskawa-authorized service center whenever an undocumented fault code appears on a VFD. Variable-frequency drives operate at lethal voltages (up to 690 V AC and high DC bus voltages) and contain large capacitors that remain charged after power-off. Incorrect troubleshooting can destroy the drive, damage connected equipment, or cause serious injury. A professional will use the manufacturer’s service software to read internal diagnostics, verify firmware integrity, and replace control boards under proper ESD precautions. If your process cannot tolerate downtime, keep a spare drive or critical option cards on hand and establish a support agreement with a local distributor.
Rough cost: A pro service call runs about $150–400 depending on whether the fix is a card reseat, option-card replacement, or full drive swap.
