Does the error happen at power-up or only during movement ? Have there been any recent mechanical changes or crashes? FS100 ALARM CODE 0910 CPU ERROR (CPU-201R)
A common cause of the A.910 code is a physical issue in the mechanical system. This can include worn-out bearings, a seized gearbox, or foreign material lodged in the mechanical transmission path. When the motor cannot freely drive the load due to a mechanical problem, it works harder, leading to excessive load and tripping the overload warning. A helpful field test is to manually rotate the ballscrew assembly through a few revolutions to feel for any binding or roughness that would indicate mechanical failure.

Yaskawa AC drives (inverters) are industry standards for precise motor control and reliability. However, like any complex industrial automation component, they utilize a sophisticated diagnostic system to protect both the drive and the connected machinery. One specific code that operators and maintenance technicians encounter is .
: Access the parameters via the digital operator or SigmaWin+ setup software. Check parameter Pn52B . If the machinery design can handle the duty cycle safely, increment this value closer to 100% to match your true production requirements. 2. Mechanical Bindings and Excessive Load If you share with third parties, their policies apply
(Overload Warning Level) dictates exact trigger points.
Intermittent contact within the motor main power phases (U, V, W) or the encoder feedback cable causes immediate current spikes. High electrical noise due to faulty shielding can also corrupt encoder signal pulses, leading to rapid, uncoordinated micro-corrections by the drive. 4. Excessive Profile Demands (Starting Torque)
: Ensure that the cooling fans on the drive are functional and that there is adequate ventilation in the control cabinet. Inspect Mechanics
