The version of the digital operator attached to the drive might not be compatible with the drive's firmware version, specifically for newer features like Permanent Magnet (PM) motor control. Troubleshooting Steps
Check the "Drive Duty Mode Selection." Mismatched duty cycles (Normal vs. Heavy Duty) can sometimes cause operational errors if the hardware cannot support the setting.
In the ecosystem of Yaskawa AC drives (like the H1000, A1000, or V1000), error codes are categorized by their severity and origin:
Once the root cause (conflicting signals) is removed, you can clear the error by pressing on the keypad or by cycling the power.
: A parameter related to the analog input gain or bias is set outside the drive's allowable limits.
: One or both of the hardwired safety inputs (typically terminals ) have been opened. Signal Timing Mismatch
Yaskawa’s engineering team can provide a or identify a hardware defect (e.g., failed current sensor).
