Set L7-01 (Soft Stall Level) to 80–100% of motor rated current. This allows the drive to reduce speed gracefully instead of tripping on latch errors. Set L7-01 (Soft Stall Level) to 80–100% of
Yaskawa, a renowned Japanese manufacturer of industrial automation products, uses a sophisticated system of error codes to diagnose and troubleshoot issues with their drives and motors. One such error code is H66, which can be a source of frustration for technicians and engineers working with Yaskawa equipment. In this essay, we'll delve into the meaning of H66, its causes, consequences, and possible solutions.
In Yaskawa AC drives, (often appearing alongside Hbb on the display) indicates a Hardwire Baseblock Signal Input fault . This is a safety-related error where the drive's output is shut off, typically because the hardware-wired safety inputs (S1–S8) have been triggered or are improperly wired.
